ABSTRACT:
Analysis of a central Indiana watershed indicates that soil erosion and sed-mentation are dynamic processes requiring careful study of alternative control programs. There are substantial differences in the efficiency and effectiveness of alternative soil loss and sedimentation reduction programs. There would be substantial savings from a policy of targeting within watersheds, in terms of soil loss reduction per dollar of program cost. Also, the within-watershed targeting concept is analyzed for both reduced tillage and for conversion of acreage to crops less conducive to soil erosion.
