Purpose | to evaluate and monitor channel condition and to identify and quantify effects of discrete sediment sources. Used as one of many elements to investigate stream condition, it is hoped that V* will provide useful data for evaluating overall habitat status, and in particular, salmonid suitability. |
Supplemental Information | Stream sediment surveys were conducted over eight watercourse reaches within the Mattole watershed between July 18, 2000 and September 22, 2000. Focused on measurements of fine sediment in pools, a quantified estimate of the fraction of pool volume filled with fine sediment can be a useful index of the sediment supply and relative mobility of a streambed. Once understood, a relationship of its effects on aquatic ecosystems might possibly be established. Vstar (V*), the ratio of fine-sediment volume to pool water volume plus fine-sediment volume, was the method employed for Mattole Salmon Group year 2000 sediment surveys. V*w, the weighted mean value of V* for a reach, was calculated for each study reach. |
