Hello, i want your help please,
Her Ras (1D unsteady flow analysis) at time 00:00 appears flood not only upstream of the river but at the entire length of the river. Is it normal?
I have a 1D project to ΗΕC RAS with no errors when the computations of unsteady flow analysis finished.
However the arrival time map from Ras Mapper, appears zero time values in the channel and in some areas beyond the channel (not only upstream of the river).
I have set the threshold depth parameter to 0.3 and the max depth to these areas is much higher.
Also i noticed that at the moment 00:00:00 water appears scattered and intermittent in different areas of my river, at the results of RAS 3d viewer.
Any ideas of what happening?
