Erosion of agricultural croplands is a significant contributor of sedimentation to reservoirs. Here, physiographic and economic models for a large agricultural watershed (2377 square miles with 27 subwatersheds) are integrated for the reduction of sedimentation of one Midwestern reservoir....

Emphasis on finding the most cost-effective ways to reduce reservoir sedimentation is increasing. Biophysical and economic models for a large agricultural watershed are integrated to estimate the average and marginal costs of reducing sedimentation with an optimal combination of land management...
