Assessment of morphometric characteristics of Chakrar watershed in Madhya Pradesh India using geospatial technique

Abstract

The quantitative analysis of the watershed is important for the quantification of the channel network and to understand its geo-hydrological behaviour. Assessment of drainage network and their relative parameters have been quantitatively carried out for the Chakrar watershed of Madhya Pradesh, India, to understand the prevailing geological variation, topographic information and structural setup of the watershed and their interrelationship. Remote Sensing and Geographical Information System (GIS) has been used for the delineation and calculation of the morphometric parameters of the watershed. The Chakrar watershed is sprawled over an area of 415 km 2 with dendritic, parallel and trellis drainage pattern. It is sub-divided into nine sub-watersheds. The study area is designated as sixth-order basin and lower and middle order streams mostly dominate the basin with the drainage density value of 2.46 km/km 2 which exhibits gentle to steep slope terrain, medium dense vegetation, and less permeable with medium precipitation. The mean bifurcation value of the basin is 4.16 and value of nine sub-watersheds varies from 2.83 to 4.44 which reveals drainage networks formed on homogeneous rocks when the influences of geologic structures on the stream network is negligible. Form factor, circularity ratio and elongation ratio indicate an elongated basin shape having less prone to flood, lower erosion and sediment transport capacities. The results from the morphometric assessment of the watershed are important in water resources evaluation and its management and for the selection of recharge structure in the area for future water management.

Variation in species assemblages due to micro-topography and flow regime govern vegetation carbon stock in seasonal floodplain wetlands

“…We attribute these to the variations in the wetland microtopographic characteristics such as depth, width, and crosssectional area in the sampling stations across the wetland. Several other studies have also inferred that the topographic characteristics of aquatic ecosystems are among the significant determinants of flow variation (Wetzel 2001;Camila de Sousa et al 2011;Yunus et al 2003;Singh et al 2014;Pandi et al 2017;Soni 2017;Prabhakaran and Raj 2018), which in turn create heterogeneous micro-environments within wetlands.…”

Assessment of Morphometric Characteristics of Wadi Al-Shumar Catchment in Jordan

“…the lowest and the highest area in the basin structure, and it explains the similarity and differences in the spatial environment of the basin. This value relates to the geological structure, extent of rock resistance against the fragmentation processes, and to the impact on the sediments' quality (4). The steep slope is closely related to the geological structure and the ability of rocks to resist the erosion, however, the high value indicates a very steep and high erosion force [5].…”

“…Morphometry is the measurement of the configuration of the earth's surface, shape and landforms dimensions using mathematical models [3]. Studying the morphometric features of catchments is very important; in order to investigate the metric measurements of the water network and hydrological properties of the catchment [4]. The geologic and climatic properties are considered the most effective agents in determining the fluvial pelvic; therefore, it is important to understand the hydrologic and geologic structures of the basin [5] [6].…”

Morphometric analysis using SRTM and GIS in synergy with depiction: a case study of the Karmanasa River basin, North central India

“…Elongated sub-basins (SW-1, SW-2, SW-3, SW-4, SW-5, SW-6) ( Fig. 4), poor drainage density and low frequency of the river basin are predictable to generate minimum peak runoff (Miller 1953;Strahler 1964;Singh and Singh 1997;Soni 2016). The Rho coefficent is a significant parameter linking drainage density to physiographic development of basin and indicates storage capacity of drainage network (Horton 1945).…”

“…Groundwater recharge potential is prejudiced by stream frequency, drainage density, drainage texture, length of overland flow, etc. Those parameters represent information about the infiltration capacity of the surface and surface runoff (Singh et al 2014;Soni 2016). Low drainage density of the sub-basins (SW-1, SW-2, SW-3, SW-4, SW-5, SW-6) is favoured of highly permeable subsoil materials or resistant lithology, under dense vegetations (Strahler 1964).…”
