Sediment Source Mapping, Detailed Channel Assessment, and Reconnaissance Sediment Budget for Williams Creek for the Period 1949 to 2001

Sediment source mapping, detailed channel assessment, and reconnaissance sediment budget for Williams Creek for the period 1949 to 2001. This study has two components: (1) sediment source mapping and reconnaissance sediment budgeting upslope of the alluvial reaches used as spawning habitat in the Williams Creek valley, and (2) detailed channel assessment of the alluvial lower stream reaches. The sediment source mapping is intended to add to our understanding of current and recent hillslope processes contributing to sediment input to the stream network, sediment movement through the stream system, and delivery to the lower stream reaches. The detailed channel assessment of the alluvial lower reaches of Williams Creek is intended to provide information about past channel changes that may have impacted spawning habitat. An understanding of past processes and current conditions is required to form the basis for planning restoration projects to enhance spawning habitat in the alluvial reaches.
