Basin morphometry? it is no longer an issue with hydromachine toolbox

Abstract

Basin morphometry is a numerically examining the shape and topographic characteristics of a drainage basin. Although basin morphometry analyses with GIS have become increasingly common in recent years, the analyses have long preliminary preparation and calculation processes for large areas. The aim of this study is to produce a new toolbox called HydroMachine with a user-friendly interface that contains variables for river basin morphometric parameters under the ArcGIS Pro 3.4 and ArcGIS Desktop 10.8 software. The toolbox was applied to a single watershed to compare it with other morphometry toolboxes and to the regional river basins with 6945 Strahler watersheds to demonstrate its capability and time-consuming. The results show that this new toolbox reduces time for all processes within 3.5 h in a regional test case, eliminates user errors and comprises 11 basin morphometric parameters. It also allows the ranking of basin morphometric parameters for flood susceptibility.
