D -- WATER QUALITY MODEL STUDY TRUMAN RESERVOIR SYSTEM LOWER OSAGE RIVER BASIN, MISSOURI SOL DACW41-96-B-0065 DUE 060596 POC Contract Specialist Arthur E Saulsberry (816) 426-5343 (Site Code DACW41) The objective of this project is to produce a calibrated model suitable for analyzing and addressing the water quality concerns of the Lower Osage River Basin (which by definition will only include Harry S. Truman Reservoir and Stockton and Pomme de Terre Lakes). Also included is the evaluation of various system operation alternatives designed to mitigate existing and anticipated water quality problems in the region of Missouri. This study includes the following major project tasks: a. Modifications to the HEC-5Q to include anoxic conditions, reservoir hydraulics considering submerged weirs, and phytoplankton transformation to the organic nitrogen, phosphorus and carbon states. Testing of the model for metals and sediments under both oxic and anoxic conditions. b. Prepare HEC-5Q data sets for all parameters and alternatives. c. Calibrate HEC- 5Q for temperature, TDS, BOD, and DO. Calibrate HEC-5Q for other parameters to include nutrients, pH, phytoplanton, iron and manganese, and inorganic sediment. d. Run HEC-5Q to analyze proposed alternatives using simple model for screening and complex model for detailed analysis. e. Update user's manual with new model modifications and Truman Reservoir system as a case example. f. Prepare a project report. g. Participate in coordination of meetings and provide a technology transfer workshop. Solicitations will be issued on or about 5 June 1996. Bids will be opened on or about 8 July 1996. Cost of specifications: NONE. Estimated cost of proposed procurement: Between $100,000.00 and $250,000.00. SIC Code: 7371.
