Hi,
Could anyone help me please ? The issue is about HEC GeoRAS concerning the DTM tiles layer, for the required surface, I don’t understand how can I use this option ? The point is that I have many DTM because the study area is too large… After many searches, I found that there is a way to use the DTM tiles, and at the end, the results of the flooded areas must be merged but I didn’t understand how ?
Waiting for you responses,
Heartily.
