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
