Role of Geographical Information System in Water Resources And Management - An Overview

Water is one valuable resource and is a primary necessity for the people, agricultural production and for the industries. Looking in to the history of the numerical modeling in the water resources area it can be seen that the general trend of modeling approach is moving from periods of 'function-centric', 'data-centric' and 'map-centric' where models would be supported by or written in GIS. This paper attemps to aware role of Geographical Information System (GIS) and the contribution of Remote Sensing (RS) in Water Resources Management.Presanted work describes importance of GIS in the flood plain management,hydrologic modeling,spatial information, watershed delination,water quality assessment and planning,Constructing a ground water simulation model and connecting the spatially referenced time series data. Limitations and constraint working with GIS mention in the presented work. Also advantages and dis advantages using GIS are narrated in the paper.
