Establishing a suspended sediment flux model for the lower Big Creek drainage: What role do fires play?

Abstract: The purpose of this project is to quantify and analyze the spatial and temporal patterns of suspended sediment delivery to Big Creek and its tributaries. Furthermore, this study will explore the effect of fire, both recent and historic, on suspended sediment delivery. The overall goal is to create a suite of suspended sediment rating curves which describes the relation between sediment flux and water discharge as a function of time since last burn and burn severity.
This will be accomplished using two methods: First, automated pump samplers will collect stream water samples for suspended sediment concentration analysis. Second, on Big Creek, at the Taylor Ranch bridge, a tethered hand sampler will be used to collect suspended sediment samples from the larger river. I anticipate that catchments that have been recently burned will produce more sediment than those that have not burned. This study will provide a measure of how much sediment is moving out of the Big Creek drainage at any given time based on stream discharge. This will be useful in measuring stream health, water quality, and the effect of sedimentation on riparian and aquatic ecosystems.
