Background Information
• Sedimentation Problem in the Great Lakes Region
• ACOE 516 (e) Program (Great Lakes Tributary
Modeling Program)
• Burns Ditch/Trail Creek Sedimentation Problem
• Internet-based Modeling Tools to assist
grassroots effort to reduce erosion

Objectives
• Develop Web-based models to quantify the impact of
land management practices within Burns Ditch and
Trail Creek watersheds
• Estimating the effect of common non-structural
agricultural Best Management Practices (BMPs) and
structural BMPs on sedimentation reduction from userdelineated watershed
• Develop Web-GIS based erosion modeling system by
drawing on existing capabilities of Digital
Watershed/MSU and Web-GIS based L-THIA and
related modeling system/Purdue and by developing
new capability to represent structural BMPs

RUSLE Model
• Revised Universal Soil Loss Equation (RUSLE)
• Follows structure of Universal Soil Loss Equation
(USLE)
• A=R*K*L*S*C*P
A: Estimated average soil loss in tons per acre per year
R: Runoff Factor
K: Soil Erodibility Factor
L: Slope-Length Factor
S: Slope Gradient Factor
C: Cover and Management Factor
P: Support Practice Factor
The RUSLE model estimated annual erosion is further modified by the sediment
delivery ratio (which is a function of watershed size) to arrive at final
estimate of annual sediment yield from a watershed
