Environmental Issues - Essay Example The current interest in environmental education is actually spurred by two factors. First is the realization of business firms that complying to environmental standards and implementing programs advocating environmental awareness could increase the preference of customers because they know that the company is very concerned with the whole of society. In other words, it has become a point of competitiveness of the companies. The second factor is the realization that the problem has become so serious to the point that it threatens all sectors of society that it needs immediate attention. The way we are made to perceive environmental issues are distorted by the way the information is relayed to us. Environmental catastrophes are relayed to the audience but its root causes are never fully explained or in some instances, not even analyzed. The ideology that pervades among corporate media practitioners is to simply relay the information but they do not go as far as promoting advocacy. There exists a problem in the way environmental awareness is understood by educators and mass media practitioners and many people in general. They tend to mention events that have harmed the environment but they seldom do point out the root cause. We can only speculate that they are constrained to do so because most of the pollution such as oil spills came from big corporations who may have interests in the establishment where they are employed or who can sue them of all their belongings for tarnishing the name of the company. Those who had the courage to speak out have been branded as agents of doom for the dark predilections that they make. Some of them are actually lampooned and criticized for their messages which bears the truth regarding the state of the environment and the role we humans are playing in its destruction. Saving the environment requires a shift in ideology, an extension of democracy where the institutions are oriented towards environmental protection rather than living in denial and abstraction. The Currents of Ecological Democracy In the contemporary setting, environmentalists have begun to take on a new perspective regarding the pursuit of environmental awareness and environmental protection. What they advocate is direct political action which refers to mass mobilization and extensive forums pressuring the government to take action rather than waiting in vain for environmentally conscious individual to get elected in office. Capitalism which is basically a general term for the desire to acquire profits is seen as totally detrimental to the environment. It is impossible to arrive to a compromise between the desire for profits and the desire to save the environment for business firms will always need to expand and exploit resources to acquire more money. If the resources such as oil are depleted in an area, they move towards another area to keep the business going. As such, the cycle of environmental degradation continues. With this line of thinking, the attempts of corporations to project themselves as environmentally conscious are but a mere propaganda that is full of deceit and lies. Private firms are not the only one to blame. Much of the toxic materials comes from weapons used by

The Percentage by Mass of Calcium Carbonate in Eggshells Essay Example for Free

The Percentage by Mass of Calcium Carbonate in Eggshells Essay The purpose of this experiment is to determine the percentage by mass of calcium carbonate in eggshells. Introduction To avoid the breakage of eggs before reaching market, the eggshells needs to be as strong as possible. The strength of eggshells is mainly determined by the percentage of calcium carbonate in it. In order to monitor the quality of eggshells, the following experiment has to be done to determine the percentage of calcium carbonate in eggshells. In this experiment, back titration is used. First, excess acid is reacted with the calcium carbonate in eggshells: 2HCl(aq) + CaCO3(s) CaCl2(aq) + H2O(l)+ CO2(g) Later, if we can find out the number of mole of unreacted acid, number of mole of calcium carbonate can then be found out. The number of mole of unreacted acid can be found by titration with the following reaction: HCl(aq) + NaOH(aq) H2O(l) + NaCl(aq) Percentage by mass of calcium carbonate in eggshell can then be calculated by the following formula: % by mass of CaCO3 = Requirements eggshell burette, 50 cm3, and stand pipette, 25 cm3 pipette filler methyl orange indicator M NaOH solution, standardized 1 M hydrochloric acid, standardized ethanol wash-bottle with de-ionized water mortar and pestle forceps safety spectacles 2 beakers, 100 cm3 volumetric flask, 250 cm3 filter funnel, small magnetic stirrer pH meter electronic balance Procedures 1.

Accurate Drainage Network Extraction From Satellite Imagery

Accurate Drainage Network Extraction From Satellite Imagery Ferdousi Khatun 1, Pratikshya Sharma1 Computer Science and Engineering Department, Sikkim Manipal Institute of Technology Majhitar, Sikkim Abstract. The extraction of the drainage hydrographical network is a key for various types of study such as hydrological analysis, geomorphology, environmental science, terrain analysis and still a research topic in the field of GIS. Drainage network are extracted through satellite image (e.g. Digital Elevation Model (DEM)) processing, contour map processing and raster map processing. Due to the advances in satellite imagery high resolution DEM are captured by many satellite recently. The DEMs is advantageous over toposheet because it provide consistent data with global coverage. Accurate drainage extraction from DEMs is used for hydrological analysis, morphometric analysis, terrain analysis and many other area as DEM provide the fastest path to extract feature. This paper provides the evolution of satellite imagery and accurate drainage network extraction process for various application namely geomorphometric analysis, hydrologic analysis, terrain analysis etc. also describe the ste ps involved to extract drainage stream network from DEM an up-to-date process. Keywords: DEM, ASTER-GDEM, SRTM, Cartosat 1 DEM 1 Introduction Water is the main and most important component on earth surface and drainage pattern is the essential hydrologic, geomorphologic element for analysis. Drainage pattern is a network that is generally formed by the waterbodies, lakes, streams, and rivers in a particular drainage basin which is also known as drainage system or river system. It has many application area like hydrologic modelling of micro watershed, groundwater prospect zone mapping, geomorphometric parameter analysis, water resource planning and management, flood hazard prediction and mitigation, river pattern change detection ,irrigation management etc. field. But drainage pattern extraction on flat surface and less complex terrain is still in research topic. The traditional process of generating the drainage map is from toposheet or contour map that depict the large scale detail of a geographic space. Generally it contains five layer of information, river and waterbody as blue color, road as red, forest as green, conto ur as brown and a black color for text feature. However, channel networks extraction from topo maps require tedious time, and cartography expert needed to provide subjective decision. In brief the steps to extract drainage from contour map is aerial element removal, linear element extraction to produce linear feature map, thinning, dilation, color segmentation and generate segmented layer map [1]. But generation of separate layer map has a limitation it will only work on digital contour map or historical map or high quality toposheet because poor quality toposheet suffer from false color aliasing and mixed color problem. Also available toposheet are old publication 10-20 years back. River pattern also change their position in some places due to landslide, flood or many natural phenomenas thus accurate drainage network is not provided by toposheet [2]. The satellites are capable of producing advanced digital elevation data(e.g., Shuttle Radar Topographic Mission -SRTM-, Interferometr ic Synthetic Aperture Radar for Elevation -IFSARE-) , Advanced Spaceborne Thermal Emission and Reflection Radiometer Global Digital Elevation Model(ASTER GDEM V2), Cartosat -1 (Cartosat DEM 1.0), Synthetic Aperture Radar(SAR) etc. so analysis became easier. Early satellite technology does not able to capture the DEM directly so for hydrologic and geomorphologic analysis DEM was generated from various satellite like QUICK BIRD,IKONOS, Landsat tm etc.[3].The most widely used satellite imagery ASTER-GDEM,SRTM-DEM etc. are freely provided by USGS(http://earthexplorer.usgs.gov/) site with 1,3 arc second spatial resolution and Cartosat-DEM is provided by ISRO(http://bhuvan.nrsc.gov.in/bhuvan_links.php) and used for analyzing the data for various study. The above mention satellite has their specific configuration and suitable for either mountain area, flat surface, medium complex terrain area for accurate river network extraction. The accuracy of ASTER GDEM SRTM -DEM and is almost same [4] . In some cases Cartosat 1 DEM better sound than SRTM DEM for extracting drainage. DEMs with higher resolution provide detailed drainage networks that has greater impact on the drainage map analysis as statistical values become lower when resolution of DEM changes from fine to rude [5]. 1.1 Evaluation of Satellite Imagery for Drainage Extraction DEM plays a crucial role for generating drainage network. In past years the DEMs were available at a global coverage in a 1 KM resolution like GTOPO-30(Global Topography in 30 arc sec).After that Shuttle SRTM ,version 4,C-band DEM of 90m resolution and the ASTER (version 2, 30 m resolution) was launched that provide better resolution which solves the problem regarding spatial resolution. The hydrology analysis became easier in INDIA after launch of Cartosat DEM (version 1) at 30 m in 2011.These data are openly accessible and easily downloaded from USGS and ISRO website. Various purchased stereo-images from Cartosat 1,landsat 7 ETM+,QuickBird,IKONOS,SPOT,SAR are used for generating the DEM using software and can be applied for hydrologic analysis[6],[7],[8],[9][10].Lot of studies is going on hydrological analysis and geomorphometric analysis from DEMs. In India most research is done best on DEM for river basin analysis, estimation of soil loss, water resource evaluation and topographi c characterization[11],[12],[13],[14].The high resolution DEMs provide finer extraction of land surface component like drainage network, slope facets and higher accuracy than a toposheet.The morphometric parameter are heavily depend upon the scale of the feature extrcated.Research is going on which satellite provided imagery is relevant for accurately extract the stream network in various surface area like mountain, flat surface, less complex terrain area.In some cases SRTM is very good for drainage analysis[15],[16]. For accuracy assessment the complete elevation criterion is more focused and less importance given to how the various morphometric variables that are derived, vary from one dataset to the other, as well as how their prepared maps differ. 1.2 Importance of Drainage Network in GIS Drainage means the deportation of surplus water from a given place. In geomorphology and hydrology a Drainage pattern is a network that is generally formed by the waterbodies, lakes, streams, and rivers in a particular drainage basin. They are depend on topography of the land. The shape, size, number of the drainage basins found in an area vary with the topography. A drainage system are of six different type namely Dendritic Drainage, Parallel Drainage, Trellis Drainage, Radial Drainage, and Rectangular Drainage and Deranged Drainage. In hydrological studies, geomorphological analysis DEMs are primary element for catchment boundary, delineation of watershed boundary, estimation of various catchment parameters such as slope, contours, aspects, etc. and morphometric attribute like no of tributaries, stream order, stream length, bifurcation ratio, relief ratio etc. By examining various hydrological and morphological parameter the irrigation management department supply water in dry weat her for agriculture crop production, water resource management department, flood hazard zone prediction and mitigation department, drainage management department are being very beneficial in recent year. 1.3 Review of Drainage Extraction Methods The mesh network of attached stream pertaining to a land is the river pattern or drainage pattern. These network formation is mainly depend on the morphological aspect of the terrain i.e. slope, varied resistance of rocks and geology and topology of the land. When a DEM is consider for drainage network extraction, the main steps are (1)fill depression,(2)flow direction,(3)flow accumulation and (4)stream network generation. A DEM is the representation of land elevation in digital form that are mainly stored as a rectangular matrix with integer or floating-point values. Among various algorithm the DEM pixels computation is based on D8 method that is first introduced by OCallaghan and Mark (1984)[17].But this algorithm has some derelictions. As per D8 algorithm single flow direction is calculated by comparing the elevation of its 8 neighboring cells where the cells with higher elevations flow towards adjacent cells with lower elevation as the water flow from high elevation to low due to gravity. However parallel flow lines generation in flat areas is the restriction of formation of concentrated channel flow and is a vital limitation of D8 method. The most important problem while delineating stream network using DEM is the presence of sinks, for flat area and depressions it is difficult to set the ends of stream network and the flow direction assignment in individual cells. Thus for accurate extraction the sinks are removed from DEM in the first step. In 1988 an new developed algorithm is introduced by Jensen and Domingue to remove the sinks prior to the flow directions calculation by increasing the elevation value of nodes within each depression pixel to the level of the lowest node on the depression boundary. Next A new method to calculate the upslope areas using rectangular grid DEM and representation of flow directions is introduced known as D-infinity where the direction of flow is not restricted to check its 8 adjacent cells[18].Some research is also done based on multipath flow direction but it is time consuming and more manual effort required for calculation[19][20].To improve the existing method a path based methods to resolve the nondispersive drainage flow direction in grid based DEM is introduced. It improved the D8 a few extent but fails to eliminate local level bias [21]. Over the past 20 years, many improved method based on routing flow through pits and flats have been introduced. The technology developed and the drainage is extracted bas ed on heuristic information. An innovative algorithm is presented by W. Yang and co -authors in 2010 based on heuristic information that accurate extract the drainage network but fails to detect unrealistic parallel drainage lines, unreal drainage lines and spurious terrain features and has a closer match with the existing pattern [22]. More recently in 2012 Mr.Magalhaes have proposed a very simple and innovative approach where the DEM is considered as island and the outside water level raises step by step until the whole DEM is submerged. So gradually it flood the cells of the DEM, next filling the depression and spread it on flat to flow towards a neighbor if that neighbor has a assigned direction of flow that does not point back to the early visited cell. In such manner, the flow direction assignments grow iteratively into flat surfaces from areas. After that flow direction is calculated and accumulation flow is generated that is the final step of stream network generation or dra inage network computation [23].In 2013 a flooding algorithm is proposed by Antonio et.al to extract the drainage on flat surface and able to works on unprocessed DEMs avoiding the problems caused by flats and pits, able to extract watercourses with a width greater than one cell and identify fluvial landforms such as marshes, lakes or river islands that are not directly managed by most of previous solutions[24]. 1.4 Literature Survey Research is going on which satellite imagery provide the accurate result for drainage extraction. DEMs provide us a digital representation of the continuous land surface. Advanced remote sensing technologies (e.g. SRTM, ASTER-GDEM, Cartosat 1.DEM etc.) are capable of generating new elevation data and freely availbale.High resolution DEM provide accurate drainage extraction. During past 20 years many satellite generated imagery is used to extract the drainage pattern and examined on various terrain like mountain area, medium complex terrain and flat surface. But the accurate extraction which is very essential for hydrologic and morphological analysis is still lacking some feature.Gajalakshmi K. and Anantharama V. recently analyses the accuracy between Cartosat 1 DEM and SRTM DEM.As per experiment in gradually undulating terrain, elevation values of Cartosat-DEM are lower than SRTM-DEM. whereas the stream parameter values of Cartosat-DEM are higher than SRTM-DEM[25]. Sarra Ouerghi et.a l. comparers the ASTER-GDEM and SRTM DEM for drainage extraction. The analysis found that ASTER GDEM is more pronounced in flat and less complex terrain [26]. Sample drainage network represented in fig 1.4. Fig 1.4. Stream networks derived from Topo DEM, ASTER GDEM, and SRTM [26] Table 1. Summary of Survey SL No Title Description Remarks 1 Water Body Detection and Delineation with Landsat 5 TM Data. Landsat 5 TM + imagery used to map river line waterbody and compared with Aerial image. Manual classification of Landsat imagery and Aerial imagery. Error in image registration occur. 2 DSM generation and evaluation from QuickBird stereo imagery with 3D physical modeling. QuickBird stereo imagery is used for generating the DEM and 5m contour generation and drainage pattern extraction. Manual process to prepare DEM Automatic extraction missing. Resolution high but time consuming process. 3 Cartosat-1 derived DEM (CartoDEM)towards Parameter Estimation of Microwatershed and Comparison with ALTM DEM. Cartosat-1 and ALTM DEM is compared for drainage pattern extraction and Microwatersheds parameter analysis in MadhyaPrades. Suitable for Mountain area but not suitable for plain area.Saveral steps required to process the DEM and extract the data. 4 Assessment of extraction drainage pattern from topographic maps based on photogrammetry Aerial Image and four toposheet is processed for drainage mapping and compare the both. Satellite imagery accurately extract drainage, some drainage is missing in toposheet. Several image processing steps required to extract pattern from satellite image. 5 A GIS based approach in drainage morphometric analysis of Kanhar River Basin, India. ASTER-DEM,Landsat ETM+,SOI toposheet for morphometric analysis All morphometric parameter has not been introduced. 2. Conclusion The extraction of drainage networks can be done form of contour map, raster map or DEMs.The satellite provided DEMs are very efficient to extract the drainage network in all terrain because the satellite gives the up-to-date changes happen on earth surface like change position of river network, new waterbody etc. feature is capture via highly sensitive sensor present in satellite. Thus less time required to extract the pattern from satellite provided DEM.Survey found that automatic extraction is accurately extract the pattern rather than topographic map with less error. The Cartosat 1 DEM is very useful for mountain area, SRTM and ASTER-GDEM is suitable for medium and flat surface where terrain is less complex.

Preserve the Oak Ridges Moraine :: essays research papers

The Oak Ridges Moraine is one of the last natural areas in southern Ontario which we can preserve for future generations. The Moraine has many natural resources that our city will need for the future. It also is has over nine hundred species of animals, many of which are rare or endangered. Lastly, there are numerous of other places to build homes on without harming twelve thousand years of history. Ruining the beautiful Oak Ridges Moraine would be a mistake because it provides many natural resources, it is home to many animals, and there are other places to build besides the Moraine. The Oak Ridges Moraine provides many natural resources, and it is crucial to preserve them, because they play such an important role in our country. Water, is a perfect example of a resource that we definitely cannot afford to waste, and the Oak Ridges Moraine is a direct source of drinking water for more than a quarter of a million people. Another resource we need to keep is trees, even thought there are a lot of trees in northern Canada, transporting them will take a lot of time and money. The moraine also forms headwaters for 4 major rivers, like the Don Rouge Humber, and Credit Rivers. We need to preserve natural resources, like water, trees, and headwaters in the Oak Ridges Moraine because they are vital to our everyday living. Within the moraine there are countless species of animals that will soon be displaces from their habitant. Many of the creatures are endangered or rare, for example the West Virginia White Butterfly, Jefferson Salamander, Red-shouldered Hawk, American Ginseng, and the Hooded warbler. Putting these animals in zoos, or special buildings is not the answer, because they will not have the surroundings that they are used to in the wild. Also, by building roads in the Moraine, there will be a bigger chance that these animals are run over, or hit by the incoming cars. In conclusion, we should preserve the Oak Ridges Moraine and its animals because they are endangered they can?t live in zoos, and may be killed by the urban environment. Even thought the Oak Ridges Moraine is a very tempting place to build, but the city of Toronto has countless of other places to build homes. One area that Toronto can build on is the Major Mackenzie and Keele area, that land will be put to good use, because we are expanding the city, and preserving the Moraine.

BIO refining

Over the last 35 years Presidents have promised to make sure that America would not have a future energy problem. Yet concern for oil and energy has also grown over the decades as the economies for both the united States and other countries have expanded. On April 28, 2010 in Macon, Missouri, President Obama gave a short speech at the POET BIO refining plant where he talked about the subjects of foreign oil dependency. The environmental costs of relying fossil fuels, and clean and alternative energies.Not o mention al the new Jobs that he believes will be created by following his energy security plan. Obama was honest in talking about how moving forward clean energy is a long-term plan that could take decades to come to fruition. In searching the University Library I did not discover any articles that openly opposed investing In alternative energies. Even though I was hoping to find at least one that was strongly opposed to Investing In clean energy to use as an opposing viewpoint. I have become somewhat of a conservationist.I am a strong supporter of recycling, and reducing what ends up in the landfills. I believe that we do need to invest in renewable energy, and that changes do need to be made to protect the environment and reduce global warming. In the end more drilling is only a temporary solution to reducing America's dependency on foreign OLL regardless of what country the OLL comes from. I was Door In ten Mont AT January, wanly makes me a Capricorn. I nouns I ah not put much faith in astrology I do find that I possess many of the Capricorn traits.I have often been labeled as being negative, but I defend myself as being a realist. My biggest peril is locking myself into Just one way of thinking. While writing this essay about drilling for more oil I found it to be a much more complex issue. There are some extremist organizations like Greenback (mm. ‘. Greenback. Org) that would have all the oil exploration immediately halted. While I understand the ir viewpoint, I do not often approve of their methods.
