Precipitation

[Xavier Torrella]

I want to create a 2D model using as boundary conditions precipitation. In all my attempts, the program runs but does not detect any flow associated with precipitation. Thanks for the help.

It sounds like the time/simulation window that is used for the Precipitation boundary condition does not align with the “Simulation Time Window” of the simulation. Confirm the simulation window aligns with the Precipitation input window.

I need some help regarding adding the precipitation in the HEC-RAS.

1- What does the actual mean of time series of precipitation? Is it mean the accumulated rainfall?
for example

Date Simulation time Precipitation (mm)
11-01-2019 07:00 00:00 30
11-01-2019 08:00 01:00 30
11-01-2019 09:00 02:00 30

Does it mean the total rainfall added on the 2D flow area during the whole simulation time is 90 mm? Please elaborate?

Thanks
