Abstract
The river basin plays a fundamental role in planning the management of natural resources. The hydrological behavior of the basin depends on the geomorphological parameters of the hydrographic basin. In the present study, a morphometric analysis was performed to determine the linear, areal and relief parameters of the Panzara River, the main tributary of the Tapi River, using the Geographic Information System tool. The river basin is of seventh order, showing a dendritic pattern of drainage that indicates the homogeneity in the texture of the basin. The drainage density in the area is 2.56 and the mean bifurcation ratio 5.065 indicates the less impact of structural deformations on the basin. The stream frequency of the basin is 3.20 showing low relief and high permeability. The present study reveals that the applications of GIS techniques are reliable, take less time and are competent to manage large databases for management of river basins.
Highlights
The important hydrological unit in any water resource planning is a river basin
The morphometric analysis of the Panzara river basin is carried out using a geographic information system (GIS) environment to find linear aspects, areas and surveys, as GIS and remote sensing is helps to understand the design and geomorphological studies of the basin [6]
The Panzara river basin is of 7th order basin as per the analysis, and it shows a dendritic pattern
Summary
The important hydrological unit in any water resource planning is a river basin. A catchment plan is a key aspect in individual water development projects as surface and groundwater sources are depleted day by day due to population growth and rapid urbanization; it becomes a necessity to identify and analyze the geomorphic characteristics and the hydrological aspects of the hydrographic basin. In the present study area, various morphometric parameters are analyzed in terms of linear, areal and relief aspect of the basin. Morphometric analysis performed with Arc GIS 10.5 to find out the parameters of the river basin such as stream order, stream length, basin length, drainage density, stream frequency, texture ratio, bifurcation ratio, form factor, form factor, circularity ratio, constant channel maintenance, constant elongation and compactness ratio etc. Basin length (Lb) Drainage Density(Dd) Stream Frequency(Fs) Texture Ratio(T)
