MAXIMISATION OF WATER RESOURCE HARVESTING USING GIS IN THE AMBEGAON TAHSIL DIST. PUNE (MAHARASHTRA)

Watershed management programmes aim at conservation of soil water resources so has to achieve improvement in the agriculture so has with the emphasis on development of regional resources. This is useful to minimize the requirement of energy, capital expenditure and heavy dependence on extra regional factors. Construction of anicuts or bunds across the lower order streams can check the outflow of water received by a micro basin. Ideally, lot of bunds are required to tap the rainfall equivalent to actual evaporation (AE) as stated by Saptarshi (1993), Bhagat (2002), Bhagat and Saptarshi (2004). However, it may not be feasible to harvest total amount of rainwater in practice. The critical issue regarding harvesting of water is where to construct the bunds because it poses problems associated with submergence of land, resource displacement and willingness of local population. Therefore, it may be advocated that small bunds may be constructed across the streams with a view of minimizing submerged area and maximizing amount of harvested rainwater. The present study aims at providing solution to this issue using GIS technique. For this, two watersheds from the Ambegaon tahsil of Pune district have been selected. The study Area:-The two watersheds of the 6th order streams viz. Guhery and Bubara have been selected. These are the branches of Ghod river (Map1) draining Ambegaon tahsil of the Pune district, Maharashtra. Both the sub basins of Ghod river lie in the moderate rainfall zone. The annual rainfall ranges from 2400mm to 2800mm. uhery basin lies in the western part receiving rainfall about 2800mm. The other basin receives comparatively less rainfall (2400mm). Topographically both the basins show high degree of slopes, high dissection index and marked by typical features of western ghats. Hypothesis:- The present study hypothesis that the GIS have been given the sites for check dams for rainwater harvesting. Objectives:-The sites for check dams for rainwater harvesting using GIS. This is the main objectives of this paper. The Techniques:-The GIS technique has been used to mark the sites for check dams for rainwater harvesting. GIS using layers representing contours, drainage and village boundaries. Methodology-The layers of contour with spot and triangulated height, 1st and 5th order streams, springs, wells, have been generated. By integrating these layers Gram ++ has given the sites for check dams for rainwater harvesting. This exercise has been carried out for two basins and results are discussed in the following paragraphs. Watershed Management-It may be assumed in any geographical study that human resource development is the reflection of development of physiographic resources. Therefore the regionalization, region wise development strategy, lead villages and clusters of development and priorities of programme have been based on spatio-temporal assessment of human resources development. The study has also attempted to find out feasibility of watershed programme in the western hiily zone of the tahsil in which rainfall is high and Mahadev Koli population is concentrated. For this, two basins viz. Bubara and Guheri have been selected. Both these are fifth order streams. A plan for management of water resource in the basin can be prepared with precision using GIS technique. The method has been explained below. 1. Guhery Basin-The map of basin has been shown in the fig (Fig. No.1). According to the analysis using GIS technique following results have been obtained (Table No.1).The program has been run for three different sizes of check dams. These are 11.20 and 25.22 hectares of area for harvesting rainwater. The results of the three programmes show that the first type of check dams may be more beneficial. It may be suggested here that construction of 56 check * Department of Geography, New Arts Comm. And Sc. College, Parner. Dist.

dams in the area of 8 villages may be suitable. 2. Bubara Basin:-The basin covers about 10 villages having population 4097. This basin is more isolated fig (Fig. 1 and 2) that the previously mentioned basin. The average rainfall is about 1800mm. The GIS program was run to identify of check dams for three different size of areas i.e. 11.20 and 25.22. The results have been complied in the table (Table No 1). It may be suggested here that check dams responsible for harvesting 655.72 MH of rainwater may be constructed. This strategy may be helpful may be decision-making regarding selection of sites. However, it is felt here

that all possible with cost should be communicated to the local people and the final decision should be taken in the gramsabha. Conclusion-The problems associated with negative impact of the Dimbhe dam have also been understood with the help of secondary as well as primary data. This exercise has proved to be useful to have the idea regarding the problems of the community. Thus, it may be stated that the hypothesis formulated in the beginning has been proved. The remedial measure suggested in the study may resolve the problems and help to maintain sustainable living of the poor section of the society.
