Performed at representative riffle sections <br />• Channel Bankfull Dimension <br />o Measure bankfull width at representative riffle sections <br />o Estimate bankfull depth at same locations <br />o Determine bankfult width-to-depth ratio at each sampled riffle section <br />• Water Depth and Velocity Measurements <br />o Measure water depth at several locations across wetted channel at <br />representative riffle sections <br />o Measure water velocity at several locations across wetted channel at <br />representative riffle sections <br />o Provide mean and range of ineasured water depths and velocities. <br />• Channel Bed Composition <br />o Perform Wolman pebble count at representative riffle sections <br />o Plot pebble count data to quantify channel bed sizes and distribution <br />o Determine the measure of embeddedness at riffles using methods <br />described in Bed-Material Characteristics of the San Juan River and <br />Selected Tributaries, New Mexico: Developin� Protocols for Stream- <br />Bottom Deposits (Hein, et al, 2004) <br />Subtask 3,2 - Support tech far RGA data collection efforts <br />Technician for field assistance to subproject lead <br />Subtask 3.3 - Data analysis and reporting on RGA <br />Upon completion of data collection and analysis, a summary of geomorphic findings will <br />be presented. A narrative for each reach will describe assessment methods, findings and <br />their interpretations. Maps will identify each reach. Data plots and data forms and <br />representative photographs will be provided. Identification of impaired and degraded <br />river functions will be the primary deliverabte of this task <br />Task 4- Coordination and management <br />Subtask 4.1 Principle Investigator, coordination and management and final technical <br />report <br />Team Leaders will discuss each others findings to identify locations and causes of <br />impaired reaches based on data collected on water quality, macroinvertebrates, <br />periphyton biomass, periphyton N15 analysis and geomorphic findings. Team members <br />will then identify opportunities for, and types of, water quality improvement projects on <br />the Animas River in coordination with the Stakehotders of the Animas River. The Principle <br />Investigator witl compile information and reports into an integrated paper and put within <br />the context of the previous research conducted in New Mexico and with historical data <br />into a final report and presentation to the CWCB, SWCD and Stakeholders. <br />Subtask 4.2 - Animas Watershed Group Coordination and Project Management <br />The role of the Animas Watershed Project Coordinator wiil be to ensure that <br />communication between the project manager and the Animas Watershed Project <br />stakeholders and other river-related community groups occurs. There will be regular <br />updates on the project status and outcomes to the stakeholders during each monthly <br />� <br />
