The surface water includes lakes, ponds, rivers, streams and other exposed inland water bodies. There will be variation in spatial extent of these features as a function of rainfall amounts, the intensity of rainfall, etc. after season / year. Remote sensing, providing lot of data and extracting a lot of information over the changes from time to time. Nowadays the role of satellite image process is widely used in extraction of water bodies. Different researchers are using various methods to delineate water bodies from different satellite imagery varying in characteristics like spatial, spectral, and temporal. Our present study, includes an automatic approach to capture the water body, from a Resourcesat-2 AWiFS (Advanced Wide-Field Sensor) imagery, using an Automated Algorithm, for extraction of surface water body’s model. The dynamics of surface water bodies in West Godavari district are studied through geospatial analysis for the extraction of water body layers for the month of December month 2016. Geospatial database on water body’s information has been created from the Resourcesat-2 AWiFS image. The model was used for the estimation of the water spread area where bands 0.52-0.59 μm (Green), 0.62- 0.68 μm (Red), 0.77-0.86 μm (NIR) and 1.55- 1.70 μm (SWIR). Quantitative estimates of water spread area (WSA) of water bodies are obtained from analyzing inter / intra seasonal / annual analysis. The WSA calculated for each is 3782 ha. The information can be used in deciding the cropping pattern in the study area.

It is an indispensable tool for all the activities of the human being; it may be a groundwater, rainwater or recycled water. The day-to-day increase in demand, availability and cost factors are playing a major role in the utilization of the groundwater for water supply needs of townships and rural areas. The availability of good quality groundwater is more important than the quantity. Water Resources of India India experiences an average precipitation of 1,170 millimetres (46 in) per year, or about 4,000 cubic kilometres (960 cu mi) of rains annually or about 1,720 cubic metres (61,000 cu ft) of fresh water per person every year. Some 80 percent of its area experiences rains of 750 millimetres (30 in) or more a year. However, this rain is not uniform in time or geography. Most of the rains occur during its monsoon seasons (June to September), with Original Article International Journal of Civil, Structural, Environmental and Infrastructure Engineering Research and Development (IJCSEIERD) ISSN (P): 2249-6866; ISSN (E): 2249-7978 Vol. 7, Issue 5, Oct 2017, 89-94 © TJPRC Pvt.
