A quantitative study of sediment delivery and stream pollution from different forest road types

Gary J Sheridan, Philip J Noske



The objective of this paper is to quantify, and enable the prediction of, sediment delivery and water pollution impacts from a spectrum of forest roads. Ten 100-200 m long sections of forest road were selected to incorporate a wide range of the key physical site factors that are likely to affect the rate of sediment generation. Each road section was permanently instrumented for 1 year to measure rainfall and runoff continuously. Suspended load, bedload, and traffic were integrated measurements over 2- to 3-week site-service intervals. Total annual sediment load (normalized for slope) varied about 25-fold, from 216 mg m-2 per millimetre of rain for a high-quality gravel surfaced road with min..
