Dear all,
I’m using Nays2DFlood to simulate flood in a relatively flat area. The 8.5×8.5 DEM file that I used does not represent the elevation in the river area correctly hence the result does not matched properly with the topography condition. I wanted to input additional elevation data (for the river area) using polygons in iRIC. But, somehow it seems iRIC does not read this polygon input. Is it indeed not possible to do this? If there is a way, can you please guide me in this matter. Thank you.

Hello,
Thank you for using iRIC.
Yes, you can use both point cloud data (or raster data) and polygon data, to be mapped to elevation data.
Please import point cloud data first, then add polygon data. Make sure that the polygon data is above the cloud data so that the polygon data has higher priority.
You can download an example project from the link below.
