In this video, and by using Arc Hydro tools and Geo HecHMS tools, i show how to extract the watershed and river charactiristics, in ArcMap.
i will extract the river lenght, river longest flow path, River profile, River slope, basin surface, basin slope, basin centroid .
Create a project for HECHMS using HEC GEO HMS AND ARC HYDRO TOOL IN ARCGIS.
DATA AND MODEL PREPARATION IN ARCGIS USING ARC HYDRO TOOL AND HEC GEO HMS
outputs:
Basin
Subbasin
Calculates area
Longest flow path
Slope of river
slope of basin
centroid of basin
shape length
catchment
adjoint catchment
drainage line and drainage point
merge basins
reach
outlet
