Specifications include, but are not limited to: TRWD is hereby inviting Statements of Qualifications (SOQs) from qualified consulting Entities to provide services to develop both a 12-year CE-QUAL-W2 model (Version 4.64 or newer) and a one or two-year 3D hydrodynamic model of your choice and for Richland Chambers Reservoir (herein called RC). TRWD has two specific goals in mind for these models: The CE-QUAL-W2 model will span the 2012-2023 period and shall be used to evaluate new pump station sites and their proximity to the existing reuse water discharge and alternative reuse discharge locations. The development of the CE-QUAL-W2 model will be the third such model for TRWD (Cedar Creek and Eagle Mountain are complete) and will have water quality added at a later date by TRWD. TRWD does not have a 3D model of choice, consulting entity should propose and defend their choice. The 3D model will represent the driest period in 2012-2023 and evaluate the same concern outlined above for the CE-QUAL-W2 application.
