The previous few years have witnessed a big curiosity in program of GIS in hydrology and water assets. this is often in part evidenced via association of sev­ eral nationwide and overseas symposia or meetings lower than the sponsorship of varied expert agencies. This elevated curiosity is, in a wide degree, in accordance with starting to be public sensitivity to environmental caliber and administration. The GIS know-how has the power to trap, shop, manage, research, and visualize the various units of geo-referenced facts. nevertheless, hydrology is inherently spatial and disbursed hydrologic types have huge info necessities. the mixing of hydrology and GIS is hence rather common. the mixing comprises 3 significant elements: (1) spatial facts development, (2) integration of spatial version layers, and (3) GIS and version interface. GIS can help in layout, calibration, amendment and comparability of types. This integration is spreading around the globe and is predicted to speed up within the foreseeable destiny. colossal op­ portunities exist in integration of GIS and hydrology. We think there are adequate demanding situations in use of GIS for conceptualizing and modeling advanced hydrologic techniques and for globalization of hydrology. the incentive for this booklet grew out of the will to supply less than one conceal quite a number functions of GIS tech­ nology in hydrology. it's was hoping that the booklet will stimulate others to jot down extra entire texts in this topic of turning out to be importance.

Wilkening (1989) used a Landsat/GIS merger for regional water resources management. Hydrologic sub-basins were manually determined and input into the GIS in vector format and then converted to raster format (60-m square cell size). This enabled the overlaying of the sub-basins with Landsat land cover data. 2. Land use/land cover classification system for use with remote sensor data by the United States Geological Survey.
