Abstract

The aim of this study was to quantify suspended sediment loading from different landscape components of Ward and Blackwood Creeks on granitic and meta-sedimentary terrain as a means of identifying and ranking dominant erosional processes. This paper presents the results of three-year study of spring snowmelt runoff in watersheds of Lake Tahoe, using a network of 9 nephelometric turbidometers. Highly eroded badland areas originating from volcanic mudflow parent material had high sediment yields. Analysis of sediment loading patterns during high and low flow events indicates that main channel-low gradient reaches act as temporary storage for fine sediment; storing during lower flows and releasing during higher flows
