Hi
I m new to HECRAS.
I would like to map the extent of a flood using HECRas.To do so I have watched and read several tutorials.
I am a GIS Engineer so I choosed to construct the geometry using Qras Plugin of QGIS.
Once the Geometry is ready (River,cross section and terrain),I have created a new project,Imported the geometry.I have adjusted manning values.
I have created 2D flow area that covers all the river and banks and have generated computation points.
I have filled the unsteady flow data with flow Hydrograph as upstream boundary condition and normal depth as downstream boundary condition.
I have run the model,no error detected but at the end once I go to Ras mapper and click the depth or velocity layers,nothing is displayed.
I tried to figure out where is the problem,without any success .
Any idea?
Thanks
