Abstract


'Wetland' denotes a large body of water surrounded by land, whether natural or artificial,permanent or temporary with water that is lentic or lotic. Wetlands perform some useful functions in the maintenance of overall balance of nature. Due to economic growth,urbanization,population increase and industrialization, more and more waste materials were discharged in to it, make it unfit for any uses. Hence to maintain the ecological balance,it is imperative to preserve these wetlands to make it fit for various purposes. Study is being undertaken in Mudigere taluk of Chikkamagaluru District, to identify the number of wetlands in the taluk and to assess the status of wetlands), Geographic Information System(GIS) is used to develop a system for the functional analysis of wetlands and to estimate the rainfall and runoff pattern using land-use/land-cover on wetlands and associated ecosystems .The study involves a detailed investigation of physical and chemical water quality parameters of 7 lake, carried out for a period of three months from March to May, the result reveals that the water is not polluted only turbidity exceeds the permissible limit due storm water runoff and 2 lakes have attended the Eutrophic condition due to agriculture run-off, sewage pollution and anthropogenic activities. A System for the Functional Analysis of Wetland using GIS,remote sensing data, topographical maps. Rainfall and Runoff pattern is estimated using land-use/land-cover, Soil using GIS and Remote Sensing Technique.
