Morphometric Analysis for Soil Erosion Susceptibility Mapping Using Novel GIS-Based Ensemble Model
Remote Sensing, 2020 The morphometric characteristics of the Kalvārī basin were analyzed to prioritize sub-basins based on their susceptibility to erosion by water using a remote sensing-based data and a GIS. The morphometric parameters (MPs)—linear, relief, and shape&#

Intraseasonal Drainage Network Dynamics in a Headwater Catchment of the Italian Alps
Water Resources Research, 2020 In the majority of existing studies, streams are conceived as static objects that occupy predefined regions of the landscape. However, empirical observations suggest that stream networks are systematically and ubiquitously featured by significant ...

A new method of drainage network extraction using SAR radar images: a case study of Djanet (Algeria)
Journal of Taibah University for Science, 2021 An oriented, connected, acyclic graph can be used to represent a hydraulic network. We can consider the network as a set of arcs and nodes. Our research work entails extracting a drainage network from satellite images by preprocessing the data to have ...
