Mayank 1 Posted July 28, 2009 Report Share Posted July 28, 2009 HelloI 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.Mayank 1 Quote Link to post Share on other sites
Chris Smemoe 1 Posted August 5, 2009 Report Share Posted August 5, 2009 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.Chris Quote Link to post Share on other sites

Clark Barlow 1 Posted August 13, 2009 Report Share Posted August 13, 2009 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_EstimatesGood luck,Clark Quote Link to post Share on other sites

Can it be updated please.Mayank Edited October 9, 2009 by Mayank Quote Link to post Share on other sites
Clark Barlow 1 Posted October 9, 2009 Report Share Posted October 9, 2009 Mayank,There is a separate table for field capacity here: http://gsshawiki.com/gssha/Obtaining_Data:Sample_Values#Overland_Parameters. It appears right after the Rawls Brakensiek table for soil parameter estimates.Clark Quote Link to post Share on other sites
