Tectonic control on drainage network evolution and evidence of neotectonic activities in of the Wan River sub-basin, Central India

Abstract

The study area lies in the Northeastern part of the Gavilgrah fault vicinity, which is one of the essential tectonic elements of the Son-Narmada-Tapti lineament, trending ENE-WSE direction. In this study field, data and satellite data observation are used for drainage characteristics of Wan river sub-basins. The course of Wan River is mostly controlled by the Gavilgrah fault and associated tectonic elements. The Wan River, which crosses the North’s fault, exhibits two river terraces that rise and continue downstream, where the river flows on the down-thrown block. The drainage characteristics of the study area were investigated by using the LISS- III satellite data. The study of neotectonism is based on field evidence and drainage pattern. The nature of the drainage pattern in the study area shows dendritic, rectangular, and parallel together and shows evidence of neotectonic activity in the study area. The longitudinal river profile, the shape of the basin, gradient fluctuations, and valley incision, and their result also indicate neotectonic activities in the study area.
