Locked Infiltration Method

Posted by Gabriel Barinas Sanchez on September 16, 2012 at 10:40am

Hi. First time participating in the Discussions so please forgive me if I'm breaking any rules by posting this.

I was working on a small project and the first infiltration method I used to calculate the runoff was the Curve Number method. I entered the data and calculated the runoff for about 10 sub-catchments and everything worked smoothly.

My client was interested in comparing the results for the other 2 methods, Horton and Green-Ampt, so I said "no problem". The problem is that when I went to change the method to each sub-catchment the software didn't allow me to.

Can somebody help me understand this behavior or how to fix this?

Thanks in advance.

    Hi, You need to change the infiltration method globally in Simulation Options,  each Subcatchment can only use Horton, Green Ampt or CN, that is why you cannot change the infiltration method.  BTW, there are no rules about posting.
