- Description
- The Bureau of Reclamation is undertaking an Integrated On-Farm Drainage (IDFM) modeling project at Red Rock Ranch, near Five Points CA, which is southwest of Fresno. This project consists of evaluating flow and transport processes resulting from reuse of drainage water at the farm. The results of this project will be applied to planning, designing, and managing the reuse of drainage water for irrigation purposes as a part of drainage water and salinity control programs throughout the western side of the San Joaquin Valley. To achieve this goal, it is essential that we develop a numerical model that fully couples the surface and subsurface flow regimes. Previously constructed models which attempt to achieve integration of the flow regimes by linking various surface and subsurface models do not provide desired results because this linkage is based on the requirement of head and flux continuity along the flow regime boundaries, continuity which is achieved by iteratively solving a series of surface and subsurface models; this approach may lead to difficulty in obtaining convergence to an accurate solution. The preferred approach for this application is to consider water flow on the two-dimensional land surface, and in the three-dimensional subsurface under variably saturated conditions. In addition to surface and subsurface interaction, the selected model must also handle salt transport in both surface and subsurface flow regimes, and must incorporate site-specific tile drain flows and evapotranspiration processes specific to the San Joaquin Valley. This acquisition is a competitive Request for Proposals using full and open competition, to which the Price Evaluation Preference for HUBZone small business concerns applies in accordance with FAR 19.1307. The solicitation will include a required performance period. For questions regarding the solicitation, contact the contract specialist, Ed Strenge, at estrenge@mp.usbr.gov or (916) 978-5144. The solicitation is scheduled to be issued on November 21, 2001. The estimated price range of the work is between $100,000 and $250,000. This solicitation will be distributed by means of the Electronic Commerce site used by the Bureau of Reclamation, which is at the following address on the World Wide Web:
