Abstract

One of the basic issues facing managers of fisheries watersheds is how inputs of sediment affect stream channels. In some cases we can measure and even roughly predict effects of land use on erosion and delivery of sediment from hillslopes to streams. But we are at a loss about how a given increase in sediment load will affect channel morphology, flow conditions, and substrate. As a result, we are unable to relate watershed processes to productivity of fish habitat. The method described here is meant to begin to fill this gap.
