Proposal for Monitoring and Research Demonstration (2)

Intensive Research Approximately 25 equally spaced cross-sections will be placed along both the treated and untreated reaches shown in Figure 2. These sections and coincident longitudinal profiles will be surveyed to produce detailed maps of channel bed and bank topography. Due to the time- intensive nature of this activity, these cross-sections will only be surveyed once a year during low flow. Composite bed and bank material samples will be collected at every other section once a year to compare and contrast possible longitudinal changes in grain-size distribution in both channels. The channel bank survey information will be used to estimate both the location and volumes of bank erosion. Photo monuments will be placed along the affected and unaffected reaches and photos will be repeated periodically to document the condition of the banks and the presence or absence of vegetation along cleared sections and island sandbars. Streamflow discharge is an important component to understanding changes that occur in the channels from management activities. Three staff gages will be installed upstream and downstream within the research reach (Fig. 2). Discharge measurements will be made throughout the year and a stage-discharge relation developed for each site in order to compute streamflow discharge entering the study reaches and leaving the treated and untreated channels (Buchanan and Somers, 1968, 1969 and Carter and Davidian, 1968). Proposed Time Line for Monitoring and Research Management activities are in two phases and the research and monitoring will reflect these activities. Manaizement Activity Research and Monitoring July 2000 ---- installation of gages, Cross sections, sediment measurement sites September 2000 Initiate Phase I vegetation removal Data collection/analysis from north channel and northern part of island and possible channel restoration September 2002 Complete channel restoration Data collection/analysis September 2003 Data collection/analysis Proposed Monitoring and Research Products The data from the research and monitoring will be compiled in two data reports. The first data report will contain data collected through Phase 1. The second report will include the remainder of the data collected during the monitoring project. An interpretive report will be prepared and published in peer-reviewed literature describing the response of the channel to clearing. Proposed Monitoring and Research Budget Summary (On an annual basis with the exception of the gage installation, management and equipment) The following budget outlines proposed budgetary responsibilities for the Cooperative Agreement/Program and the USGS.
