Selection of potential waste disposal sites around Ranchi Urban Complex using Remote Sensing and GIS techniques
Results of Selection of Solid Waste Disposl Site: -
Based on image interpretation of LISS III Ranchi image five possible sites for waste disposal has been identified . On the basis of actual field data, parameters of site sensitivity index are given weightage. The value of sensitivity index is multiplied by the corresponding weightage, results in a score of the parameters. Different classes were ranked on the basis of overall score obtained by them and presented in Table 3. Table 3: - Summary of Site Ranking and Classification:-
The total score for proposed disposal sites are varying from 337 to 494.On the basis of results obtained from the table-3 Site no 3 scored lowest score- 337 i.e.- Areas near to Balsiring, ranked GOOD. Sukurhutu i.e. Site no 1 scored 338. Score of these two areas are near about same. Capacity of these two sites is quite large and waste disposal for these sites may be continued for more than 5 years and therefore these two sites are considered to be the best site for disposal of Municipal solid waste for Ranchi. Site no 5 scored highest 494. MSW disposal might affect population here. Waste disposal is recommended here with proper management practices. Conclusion: - In this study it was tried to find out the potential waste disposal sites using RS and GIS techniques for Ranchi Municipal Corporation.Selection of suitable sites for waste disposal is based on several factors. During analysis it was observed that the best site for disposal of waste is Sukurhutu and Balsiring. The main advantage of this site is the availability of vast stretch of wasteland and fully developed transportation network. Site no 5 scored highest among other sites, found to lie in ward number18 disposal of organic waste for Composting is recommended so that the inhabitants of this area may get benefited by its Manurial output. On the basis of integration of various parameters IRS- IC, PAN and LISS III imagery and GIS as tool have been found to be very useful for the interpretation and identification of waste disposal site. Thus with the use of these technologies management of municipal waste will no longer be a problem for city administrators. References: -
