[GRASS-user] r.sim.water - error

[M S]

When I run r.sim.water, I get the following output
"GRASS_INFO_WARNING(18240,1): Infiltration exceeds the rainfall rate
everywhere!  No overland flow."

If I understand all the inputs correctly, one inputs the rainfall excess
(runoff) and the rainfall infiltration, and the intensity (rate) is
calculated by the module by the equation (Rainfall Excess = Rainfall
Intensity - Infiltration rate).

How can my infiltration exceed the rainfall rate if rainfall rate =
Infiltration + runoff?
