Geographic information systems has evolved useful and important tool in the field of hydrology for studying and managing Earth's water resources. Climate changes have greater demands on water resources. Occurrence of Water changes its spatially and temporally throughout the hydrologic cycle, Previously GIS systems were mostly static in their geospatial representation of hydrologic features, GIS platforms are becoming dynamic, between historical data and current hydrologic reality. Water resource management is consideration for development sustained in area. Computer aided analysis for resource management remote sensing technique with GIS has been developed. Utility of integration of satellite image data with that of geo referenced overlays produced from map and tabular data bases Remote Sensing, coupled with Geographic Information System is a powerful tool for monitoring the water quality and water pollution. Satellite imageries are used successfully in determination of various water quality parameters like Total Suspended Solids, turbidity, chlorophyll content, color, temperature etc. Using Visible, Reflected Infrared and Thermal Infrared bands of the Electro Magnetic Spectrum. Sustainable management of water resources uses Remote Sensing techniques.
