Attribute of soil as input for GSSHA

Recommended Posts

Hello

I am using GSSHA for soil moisture mapping. Can you refer a web address to get the exact figures of various soil attributes (e.g. KSat, Field capacity for different soil types). I have gone through many books and websites but most of them have controversy regarding the figures. Also the figures of Ksat & Field Capacity used in SSURGO_Soil.dbf (Park city in example data) and GSSHA.cmt (used by WMS, while creating inputs for GSSHA) are too much different.

Hi Mayank,

There was a paper written by Rawls et al. (1983?) in one of the ASCE journals that has some or all of this information. Also, I'd look at gsshawiki.com for units and other information about these parameters. I don't have the exact references right now.

Waiting eagerly for your next response.

Mayank:

Try this: http://gsshawiki.com/gssha/Obtaining_Data:Sample_Values#Overland_Parameters Scroll down to "Table 1. Rawls & Brakensiek soil parameter estimates."

The table is also shown here with more explanation on how the parameters are used: http://gsshawiki.com/gssha/Infiltration:Parameter_Estimates

Good luck,

Clark

Hi clark

The figures of field capacity are missing in the second wiki link. Can it be updated please.
