  Citation × Citation Citation Abstract Copy Title: Upper Spokane River Model: Boundary Conditions and Model Setup, 2001 Author: Slominski, Spencer, Annear, Robert Leslie, Berger, Chris, Wells, Scott A. Year: 2002 The Washington Department of Ecology is interested in a water quality model for the Upper Spokane River system for use in developing Total Maximum Daily Loads (TMDLs). The goals of this modeling effort are to: • Gather data to construct a computer simulation model of the Spokane River system including Long Lake Reservoir and the pools behind Nine Mile dam, Upper Falls dam and Upriver dam for 2001 based on the calibration conducted for 1991 and 2000 data sets, (Annear et al, 2001). • Ensure that the model accurately represents the system hydrodynamics and water quality (flow, temperature, dissolved oxygen and nutrient dynamics) for the three simulation years A hydrodynamic and water quality model, CE-QUAL-W2 Version 3 (Wells, 1997), is being applied to model the Spokane River system. CE-QUAL-W2 is a two dimensional (longitudinal-vertical), laterally averaged, hydrodynamic and water quality model that has been under development by the Corps of Engineers Waterways Experiment Station (Cole and Wells, 2000). In order to model the system, the following data were required: • Spokane River flow, water level and water quality data at the upstream system boundary (the State of Idaho boundary) • Tributary inflows and water quality • Meteorological conditions • Bathymetry of the Spokane River, the dam pools along the river, and Long Lake Reservoir • Point source (wastewater treatment plants, WWTPs) inflows and water quality characteristics Data have been primarily collected from 1991 to 1992, during 2000, and more recently during 2001. This report summarizes the 2001 data used in the modeling effort to expand the model calibration period.

Year: 2006 The purpose of this study was to improve the existing Version 3.0 application of CE-QUAL-W2 of the Pend Oreille River between Box Canyon Dam and Albeni Falls Dam by performing the tasks outlined above. In addition, the use of field data from 2004 as an additional calibration year would improve the confidence in the model’s predictive ability for temperature. The model simulations were run from January 1st to December 31st in each of the 3 years of model simulation: 1997, 1998 and 2004. The model chosen for development is CE-QUAL-W2 Version 3.5 (Cole and Wells, 2006). This is a twodimensional unsteady hydrodynamic and water quality model that includes typical eutrophication parameters (algae, nutrients, temperature, organic matter, dissolved oxygen, pH). The PSU-WQRG is a center for development of this modeling tool (see http://www.cee.pdx.edu/w2).

  Citation × Citation Citation Abstract Copy Title: Pend Oreille River, Box Canyon Model: Model Scenario Simulations Author: Berger, Chris, Annear, Robert Leslie, Wells, Scott A. Year: 2007 The Washington Department of Ecology is interested in developing a temperature Total Maximum Daily Load (TMDL) allocation for the Pend Oreille River between the Albeni Falls Dam (U.S. Army Corps of Engineer’s reservoir) and Box Canyon Dam as shown in Figure 1. The Pend Oreille drainage basin is shown in Figure 2. An existing model of the Box Canyon reach was updated from CE-QUALW2 Version 3.0 to Version 3.5. This current research involves improving the calibration of the original model (1997 and 1998) and expanding the model using 2004 as an additional data set for calibration. The use of field data from 2004 as an additional calibration year was chosen to improve the confidence in the model’s predictive ability for temperature.

Figure 1 shows the river system and an outline the boundaries of the City of Spokane. The Washington Department of Ecology (Ecology) is interested in a water quality model for the Upper Spokane River system for use in developing Total Maximum Daily Loads (TMDLs).

Since the City of Spokane and other point dischargers to the Spokane River have taken considerable field data in the Spokane River system during 2001, the City of Spokane funded this study primarily to: • Continue the development of the Spokane River model for the year 2001, and • Ensure that the model retains its calibration for the year 2001 A hydrodynamic and water quality model, CE-QUAL-W2 Version 3 (Wells, 1997), was applied to the Spokane River system for the years 1991 and 2000.
