The RHEM Web Tool

Published by Agricultural Research Service | Department of Agriculture | Metadata Last Checked: January 27, 2026 | Last Modified: 2024-02-15
The RHEM Web Tool is a web-based interface for the Rangeland Hydrology and Erosion Model (RHEM). The interface allows users to input commonly known rangeland characteristics and use parameter estimation equations to construct model input files and run the RHEM model. 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. This web application was built with the following goals in mind: Simplify the use of RHEM Manage user sessions Centralize scenario results (model runs) Compare scenario results Risk assessment Provide tabular and graphical reports Resources in this dataset:Resource Title: The RHEM Web Tool.
