Agricultural and Biosystems Engineering

Since 1905, the Department of Agricultural Engineering, now the Department of Agricultural and Biosystems Engineering (ABE), has been a leader in providing engineering solutions to agricultural problems in the United States and the world. The department’s original mission was to mechanize agriculture. That mission has evolved to encompass a global view of the entire food production system–the wise management of natural resources in the production, processing, storage, handling, and use of food fiber and other biological products.

History
In 1905 Agricultural Engineering was recognized as a subdivision of the Department of Agronomy, and in 1907 it was recognized as a unique department. It was renamed the Department of Agricultural and Biosystems Engineering in 1990. The department merged with the Department of Industrial Education and Technology in 2004.

Abstract

The Environmental Health and Safety Storm Water Program has used the RUSLE2 model for many years to quantify success by measuring the effectiveness of the ISU campus Storm Water Management Program. RUSLE2 provided estimates of the soil loss prevented by implementing Best Management Practices (BMPs) specified in the Iowa Statewide Urban Design and Specifications for construction sites. ISU reports these estimates to the Iowa Department of Natural Resources each year in the annual report required by the Municipal Separate Storm Sewer System (MS4) permit. With the development of the newer WEPP (water erosion prediction project) model, it is beneficial to update the model used by Environmental Health and Safety as well. WEPP will help ISU stormwater managers visualize the multi-year effects of SUDAS BMPs and predict the benefits of long-term soil management.
