MEASURING SURFACE EROSION ON FOREST ROADS AND ESTIMATING COSTS OF EROSION CONTROL--PRELIMINARY RESULTS

Simulated rainfall was applied to three types of roadway on six sections of forest road to measure runoff and sediment yield. The three surfaces were native granitic material, native material treated with dust oil, and bituminous surface treatment. The roads are located within the Silver Creek Experimental Watershed, Boise National Forest, Idaho. Test plots of the roadway were isolated from the adjacent roadway with barriers sealed to the surface. Discharge and suspended sediment were sampled continuously. Rainfall was simulated by a large sprinkling infiltrometer at a rate of 2 in/h for 25-40 min. The first test was conducted on a dry plot, followed by a second test 24 h later. Measurements for each plot included bulk density by depth increments, loose soil on the road surface in pounds per unit area, particle-size distribution for each sample, gravimetric soil moisture before and after each simulated rainfall, and a detailed survey of each plot. Result of runoff and sediment yield measurements are presented. Construction costs for standard and nonstandard items on forest roads were determined by recording the labor and equipment necessary to complete each activity based on local rates. Programs for estimating costs of erosion-control features were developed for the HP-41CV calculator and minicomputers with BASIC language capability. Cost estimates derived from current estimating procedures are compared with costs developed from observed labor and equipment times. (Author)
