Hello all,

I am new using the RETC Van G. model software. I have done a WP4C, tempe cell, and Ksat lab work on a soil core. Now i am using the RETC software. My question is, I am confused on what values to enter under the (Qr, Qs, Alpha, n, I, Ks) .

I have all my soil bulk density and ksat information but i need to make a soil retention curve graph with RETC with my soil core. Help.

Please note that the Discussion forum is not a substitution for familiarizing yourself first with technical manuals for a particular software. For RETC, that would be:
