HecRas 6.3.1 for beginners

Here you can find a general explanation of HecRas 1D modeling of flow.
I talked about how to find the projection file, how to find the river centerline, DEM file and Rasmapper, adding a bridge, evaluating the results, flood zone and etc.
If you have an accurate DEM file then you don't need to add cross sections from the excel file.
