Not getting any flow

Recommended Posts

Hi,

Am exploring GSSHA to map soil moisture for some sites in India. My problem is that I am not getting any flow. Hydrograph is linear on zero. The area on which I am working is sandy but I have tried with even rainfall of 150. I am attaching snapshot of the soil attributes I am taking. I have also tried to add flow to the channels but no output was there.

Mayank,

I haven't looked at your values in detail, but I'd try lowering your hydraulic conductivity values. Also, check out your GSSHA summary (.sum) file and make sure the problem is too much infiltration. It probably is.

Hi Chris,

The problem is exactly with the figures I am giving for soil parameters.Because most literature has advised KSAT above 150-200 for sandy soil I have given the same, but due to this figure every drop is getting infiltrated.
