Creation Of Remotesensing And Gis Based Physical Characteristics Information System For Surface Water Management : A Model Study

摘要

The demand for water is increasing day by day due to increasing population , rapid urbanization, industrial growth and agricultural utilization. The levels of Water Resources is decreasing over years due to all the above activities and decreasing of annual rainfall year by year due to climatic changes and increasing runoff due to urbanization and deforestation. Hence, it is necessary to increase water Resources and maintain the quality of water along the riverbeds due to urbanization the changes of physical characteristics is impacting the water Resources to meet for future demands. Keeping this in view, we have done a model study for along the musi riverbed. The Study area is situated at Hyderabad district and very less part coming into the Nalgonda district of Andhra Pradesh between The part of Survey of India toposheet 56 K/11 and is situated between 780301 and 780451 East longitudes and 170201 and 170251North latitudes The present study was carried out to delineate physical characteristics study along the musi riverbed using IRS-ID PAN and LISS-III geocoded data on 1:50000scale.The information on Basemap,Drainagemap,Watershedmap,Slopemap,Landuse/Landcovermap,structures map and were generated. Geographical Information System was used to prepare database on the above layers, analysis of relationship and integrated the above data to study the physical characteristics along the musi riverbed. The result in the form of integrated maps could be properly analyzed using the advantage of technology like GIS as the methodology, which includes analysis of many resources and their interpretation. River beds study and to prepare any action plans along the river beds is useful for to meet future demand
