Abstract:

A prediction equation is presented for estimating the storm-induced increase in suspended sediment yield in a stream system due to highway construction. The equation was developed by regression analysis of data collected at nine stream-gage sites in five watersheds in Pennsylvania. Two hundred and seventy eight sets of data were included in the analysis. The equation relates factors that describe soil erodibility, rainfall, construction phases, and proximity of construction to the stream system to the increased quantity of sediment transported. The result indicates that the sediment carried by a stream increases with soil erodibility, storm-erosion index, area cleared and grubbed, cut-and-fill heights, and proximity of construction to the stream. The form of the final equation was found to be rational but the standard error of estimate was large, although not exceptional when compared with the results of other sediment-transport studies. It is concluded that the equation may be a useful tool in highway location studies, evaluation of highway development impact, and design of sediment catchment devices. (Authors)
