hi, I would like to simulate rainfall in RMA4. I read on the user's guide that I have to provide to RMA4 the same rates given to RMA2 for the simulation of rain. But I haven't found any practical example. So if a run a simulation in RMA2 for 2 hours with these values for rainfall: time 0 --> 0 cm/h, time 1 --> 2 cm/h, time 2 --> 5 cm/h, in order to simulate rainfall in RMA4, is it right to add the RA card to the file .trn in the following way? file .trn: T1 T2 T3 RA 1 0 RA 1 2 RA 1 5 ....... And if this is not the right way, can you give me any suggestion? Anna
