Erosion and deposition modeling tutorial

C-factor estimation

Steve Warren, Matt Hohmann, Tom, Ruzicki, Helena Mitasova

DRAFT - UNDER DEVELOPMENT, finalize regressions using landsat8, add photos to help assign C-factor

Universal Soil Loss Equation C-factor tables

C-factor based on NLCD land cover classification (DRAFT)

Fort Campbell:

   Forested areas: C=0.001 (Wischmeier and Smith, Table 11), 
   OR 0.003 (Dissmeyer and  Foster, Table 3) x 0.5 (Dissmeyer and Foster, Table 5) = 0.0015

   Meadows: C=0.013 (Wischmeier and Smith, Table 10)

   Ag fields: regress imagery with field-determined C-factors  C-factors

Yakima:

   All areas: regress field-determined C-factors multiplied by 0.1

Fort Hood:

 Forested areas (as determined by imagery):  C=0.002 (Dissmeyer and Foster Table 3 x Table 5)
 
  All non-wooded areas: regress imagery with field determined C-factors multiplied by 0.1

Schofield Barracks:

 All forested areas: C=0.0001
 
  All non-forested areas: regress imagery with field based C-factors multiplied by 0.1

Eglin AFB:

  Forested areas: see if it is possible to differentiate levels of forest canopy using imagery
 
   Non-forested areas:  see Ft. Hood
