Rock Chute Design

    This Excel spreadsheet is included as a tool to design rock chutes for conservation practices. Median size for rock is determined along with the chute hydraulics and dimensions. This spreadsheet is based on "Design of Rock Chutes" by Robinson, Rice, and Kadavy, ASAE Vol. 41(3), pp. 621-626, 1998. One Spreadsheet version is included. Rock_Chute.xls is intended for Excel in Microsoft Office 97. The program was developed by the Iowa design staffa nd modified by the WI-engineering staff. The Excel file (.xls) ispassword protected. A Glossary is included.

      The RHEM Web Tool

        RHEM is designed to provide sound, science-based technology to model and predict runoff and erosion rates on rangelands and to assist in assessing rangeland conservation practice effects. RHEM is a newly conceptualized, process-based erosion prediction tool specific for rangeland application, based on fundamentals of infiltration, hydrology, plant science, hydraulics and erosion mechanics.
