Watershed Prioritization Based On Morphometry Analysis for Groundwater Potential Maharashtra (India)

Abstract

Drainage basin analysis is giving a quantitative description water resource of the area. The aim of present study is to identify the morphometric parameters of watershed condition in Panjhara River basin of Sakri Taluka in the state Maharashtra, India. Study areas divided in to 6 sub-watersheds which are nomenclature by groundwater survey and development agency for upper Panjhara River. The study area is having homogeneity in texture and lack of structural control. The steam order is 1st to 6thin all sub-watersheds with dendritic drainage pattern. The work included as the significance of digital elevation model (DEM) for gathering details on Drainage Network (stream order, stream number, stream length, stream length ratio and bifurcation ratio), drainage texture (stream frequency, drainage density, constant of channel maintenance, length of overland flow, total basin relief and relief ratio) and basin geometry (form factor, elongation ratio, texture ratio, circularity ratio drainage texture and compactness coefficient) characteristics. Each parameter has been assigned their ranks according to their weightage and low parameter value is ranked as first and so on. The lowest value sub- watershed TE-103 is considered as high priority for adopting conservation measures. The suitable locations for conservation structures like check dam, nala plugging and percolation tank in high prioritized sub-watersheds, were also identified for the appropriate land and water management system. The highly prioritized zone in structural condition will also useful for mark important location for structures. Although understanding of soil erosion and deposition of earth material.
