About Delhi
Deep, somewhat excessively drained soils formed in wind-modified alluvium from granitic rock sources. Found on dunes and terraces.
K factor values are sourced from the USDA Natural Resources Conservation Service (NRCS) SSURGO database.
Using Delhi in a RUSLE calculation
For a California construction project, use the soil K factor with rainfall erosivity, slope length and steepness, cover management, and support practice inputs. The K factor represents the soil erodibility portion of the model, so selecting the soil series that matches the site is important for defensible stormwater documentation.
In a SWPPP workflow, the practical question is not just what soil type is mapped near the project. It is whether the mapped series, K factor, and drainage assumptions match the site evidence well enough to support the RUSLE or RUSLE2 calculation.
California Distribution
Found in Merced, Stanislaus, and Madera counties. Low K-factor due to sandy texture, but vulnerable to wind erosion.

Delhi soil FAQ
What is the K factor for Delhi soil?
Delhi has a listed K factor of 0.17 in the Rapid RUSLE soil directory. Confirm final values against project specific soil survey data before submitting permit documents.
Where is Delhi soil found in California?
Delhi is mapped in Madera, Merced, Stanislaus. County mapping is based on available soil series data and should be verified for the exact project location.
How is Delhi used in RUSLE erosion calculations?
Use the Delhi K factor as the soil erodibility input in RUSLE or RUSLE2, along with rainfall, slope, cover, and support practice factors for the site.
