- Description
- This is not the Solicitation. The solicitation should be posted on or about December 7th, 2009 PURPOSE: The purpose of work is to assess the current sediment yield and the feasibility of sediment reduction measures in agricultural and mixed-use watersheds of the Lower Snake River Basin. The assessment data and findings will support development of the Programmatic Sediment Management Plan. The main elements of the work are described below. Assemble Supporting GIS Data for the Study Area. Essential data and reports will be compiled for the study area to support the evaluations performed for this project. The sediment delivery area of the lower Snake River Basin is approximately 32,000 square miles. The dominant land cover types in the study region are forestland, shrubland and grassland. According to the 2001 National Land Cover Dataset, approximately about 14 percent of the area, 4,400 square miles, is classified as agricultural land. This investigation will assess sediment yield and evaluate the effectiveness of potential sediment reduction measures in the predominantly agricultural subbasins of the study region. The agricultural subbasins include portions of watersheds of the lower Clearwater River, South Fork Clearwater River, Potlatch River, Palouse River, Grande Ronde River, Tucannon River, and Asotin Creek. The area to be considered is approximately 7,800 square miles. The investigation will adopt a sample-based and engineering modeling approach to evaluate sediment delivery. It is not feasible to evaluate sediment yield from all individual agricultural fields and streams reaches for this large study area in the time available for development of the PSMP Environmental Impact Statement (EIS). It is expected that the evaluation will use existing readily available geographic information system (GIS) datasets and other data that is currently available to researchers that are engaged in the analysis. Metadata for the digital datasets will meet the Federal Geographic Data Committee (FGDC) standards. Extensive collection of new sediment yield field data is not authorized for this project. Limited field data such as photographs and inspection notes is permitted when this is necessary to validate the assessment approach. A database listing of the data used in the sediment yield assessment will be made available to the Corps. At the Corps discretion, all or part of the data used in the analysis will be delivered to the Corps in digital format. ADDITIONAL INFORMATION: Fingerprinting Sediment Sources using Neutron Activation Analysis, ICP-MS, and X-ray Fluorescence. Sediment fingerprinting is the terminology used to identify the origin of sediment sources within a watershed by characterizing a number of diagnostic physical and chemical properties. Sediment fingerprinting can be used to define sediment sources and transfers within drainage basins based on the assumptions that: 1, the potential catchment sediment sources can be distinguished on the basis of their physical, geochemical and biogenic properties or fingerprints; and 2, a relative comparison of the sediment fingerprints can be made with values obtained from the original source materials. There are several possible alternative techniques that can be used to identify these properties, and the process should involve several different alternative diagnostic properties, rather than a single indicator, to establish the consistency of the results obtained. The use of composite fingerprints in combination with a multivariate mixing model can then provide a basis for estimating the importance of individual catchment areas and specific source types.
