Rawls rate question
Rawls rate question
(OP)
See Table D 13.1 http: //www.mde. state.md.u s/assets/d ocument/se dimentstor mwater/App nd_D13.pdf
(sorry if it takes a while to load, didn't find a clean table elsewhere on the web) It is the Rawls, Brakensiek and Saxton, 1982 "Rawls Rates" table.
What confuses me is the inclusion of soil texture class AND hydrologic soil grouping. My dilemma is this, I have a location that is mapped as HSG D and it is a Loamy Sand confirmed by deep observation holes. For infiltration design would the texture class rule or the HSG? If is is the texture then why are HSGs included in the table?
TIA!

RE: Rawls rate question
In Illinois the State Soils Maps seem to be pretty accurate but there are always discrepancies.If you have a geotech report, borings or test pits, use them as they are much more detailed than a general county/state soils map (especially for infiltration calcs).
