Delineation of Drainage Pattern and Water Projects - A Geographical Overview

Abstract

In the context of present study the term Delineation means bordering of any kind of area by using scale and reveals in maps. In the context of present study the term Delineation is refer to mapping the drainage and check dams in the study area. The region is drained by the Arunavati River a northern tributary of Tapi, flowing towards the south. River Aner in the east marked an eastern boundary, which flows towards south while in the west Nandurbar district and in the east Jalgaon district. The Northern boundary is marked by Madhya Pradesh. The basaltic lava flows in the hilly tract are not favorable for groundwater development but give rise to perennial and seasonal springs. The contact of the basaltic lava flows with alluvial mountain front deposit is demarcated by a major fault. The alluvial deposits are further subdivided into (a) Talus and Scree deposits bordering in the Satpura foothills and (b) Alluvium consisting of sand clays gravel. Secondly, Evapotranspiration is an important parameter to decide the quality of water is available for plant growth. Evapotranspiration in this tehsil is higher during the plant growth period, thus reducing the availability of water for plant growth. Drought Prone Taluka the semi-arid tracts of the State which receives rainfall between 750 to 1000 mm are drought-prone areas. The Shirpur taluka comes in the drought-prone area of the State. The annual normal rainfall is 617 mm received over period of 36 days during south west monsoon. A surface water resource in the Taluka is unevenly distributed. This resource is also not assured as it depends on rainfall. Irrigation projects in the Taluka cover the only small area in southeastern part of the Taluka. Because of this, the use of groundwater for irrigation, drinking water, and an industrial purpose has increased many folds. In entire taluka intensive development of groundwater has led to critical situations resulting in manifestations of problems like declining ground water levels, shortage of water supply, etc. This situation warrants for taking up programmers to augment groundwater resources on strong lines in the whole taluka. In this paper, groundwater resources in different formations of the entire taluka, industrialization, problems caused due to excessive utilization of groundwater, method store adopted in conserving the scarce resources and recharging the aquifers have been discussed.
