RBM10 Hydrodynamic Modeling and Scenario Analysis

The contract seeks a small business to conduct hydrodynamic modeling of the Klamath River using the RBM10 model to simulate water temperature dynamics under two distinct scenarios: one where existing dams remain in place and another where the dams are removed. The primary objective is to assess how these contrasting conditions affect thermal regimes in the river and, by extension, the suitability of habitat for fall chinook salmon, a species of ecological and regulatory significance. The modeling effort must capture spatial and temporal variations in water temperature, incorporating environmental inputs and riverine characteristics to produce accurate, scientifically defensible outcomes that can inform fisheries management and restoration decisions. The work is classified as a subcontract under the North American Industry Classification System code 541620, indicating it falls under scientific and technical consulting services. It is set aside exclusively for small businesses as defined by the SBA, with the solicitation issued by the Department of the Interior’s Office of Acquisition Grants. The response deadline is August 3, 2026, and the work is expected to be performed in support of federal resource management goals, though the specific place of performance is not indicated. The outcome of this modeling will provide critical insights into the potential ecological benefits of dam removal, contributing directly to ongoing efforts to restore native fish populations and improve river health in the Klamath Basin.
