Morphometric based prioritization of watershed for groundwater potential of Mula river basin, Maharashtra, India

Abstract

Morphometric analysis gives a quantitative description of drainage basin. The main aim of the present study is to identify the morphometric parameters of a watershed of Mula River basin, Pune district of state Maharashtra, India, and to prioritize the sub-basin. The work outlines the significance of digital elevation model for assessment of drainage pattern and extraction of relative parameters. Basin has been divided into 5 sub-watershed namely SW1 to SW5. The stream order of watershed ranges from first to sixth order and have dendritic drainage pattern means homogeneity in texture and lack of structural control. Further, each parameter has been assigned their ranks according to their value. The basin with lowest parameter value is ranked as first. It was considered as high priority for adopting conservation measure as well. The suitable locations for conservation measure structures in highly prioritized sub-watersheds were also identified for the appropriate land and water management plane. The relevance of work shows the appropriate measure structure locations for preventing the soil from getting eroded from the highly prioritized sub-watershed. INWASCON OPEN ACCESS

The Implementation of a Hybrid Model for Hilly Sub-Watershed Prioritization Using Morphometric Variables: Case Study in India

“…Over recent years various researchers have used morphometric variables (i.e., linear, areal, and shape) to prioritize watersheds using the application of remote sensing (RS) and geographical information system (GIS) by ordinary methods [4][5][6][7][8][9][10][11][12][13]. For instance, Shrimali et al [4] applied the feasibility of RS and GIS techniques to contextually investigate the Sukhana lake catchment in the Shiwalik hills to prioritize the soil erosion zones.…”

Watershed prioritization for soil and water conservation aspect using GIS and remote sensing: PCA-based approach at northern elevated tract Bangladesh

“…The change in stream order suggests that streams flow from high altitude with less lithological variations. Rai et al (2014) and Choudhari et al (2018) notice that maximum stream order is found in first-order streams. Stream order is shown in Fig.…”

“…Dendrite to the sub-dendrite stream has been obtained for the proposed site. According to Choudhari et al (2018), dendritic drainage pattern shows homogeneous and uniform Barind Multipurpose Development Authority (BMDA).…”

“…The morphometric study describes basin characters and gives the concept of geological and geomorphic history for the drainage area (Strahler 1964). Literature review shows that morphometric analyses involve evaluation of linear, aerial and relief parameters (Choudhari et al 2018;Farhan et al 2017;Rahaman et al 2015;Singh et al 2014;Meshram and Sharma 2015;Gajbhiye et al 2014;Rai et al 2014Rai et al , 2017aRai et al , b, 2018Rai et al , 2019Magesh et al 2012;Sharma et al 2018).…”

“…But now the digital elevation model (DEM) with the combination of topographical sheet and field survey data is used in rapid, more precise, updated and cost-effective manner for the watershed analysis (Maathuis and Wang 2006;Moore et al 1991). According to Choudhari et al (2018) and Sreedevi et al (2013), morphometric parameters were derived from Shuttle Radar Topographic Mission (SRTM) DEM and works on C-band interferometry radar setup. Yadav et al (2014) used CARTOSAT DEM for the morphometric analysis purpose.…”
