Description:  

This dataset is the Water Erosion Prediction Project (WEPP) calculations generated from the GTRN roads and trails network data. The Water Erosion Prediction Project is a model developed to estimate water erosion and sediment delivery off of a land surface. A subset of this model "WEPP Forest Road Erosion Predictor" was used to estimate erosion and sediment delivery from the JDRMP plan area road network. Model input parameters include road design, road surface, traffic level, road gradient, road length, road width, fill gradient, fill length, buffer gradient, buffer length, rock fragment percent, soil texture, and climate. These input factors are estimated for each segment of road and the model is run for 30 years using a climate representative of the road segment area. Outputs for each road segment are average annual sediment leaving road segment (lb), and average sediment leaving buffer (lb). The sediment outputs were summarized and totaled by road designation for comparing alternatives.

Purpose:  

This dataset is intended for analysis in the John Day Resource Management Plan (JDRMP).
