Water Quality Modeling of Lake Monroe Using CE-QUAL-W2.
Abstract
CE-QUAL-W2 was applied to Lake Monroe to enable the Louisville District (CEORL-ED-H) to have the capabilities of evaluating changes in water quality from changes in environmental conditions. Calibration was conducted for 4 years of observed data provided by the CEORL-ED-H for six water quality constituents of interest. Calibration results for all years except 1994 were affected by having limited inflow and inlake profile data. Given the limitations to the boundary conditions to drive the model, favorable results were obtained for all years. After calibration was achieved, six scenario runs were conducted to determine effects of low/high inflows, air temperatures, and nutrient loadings on water quality using the 1994 calibration results as the base run for scenario comparisons. In general, the scenario results showed that increased nutrient loadings to the system resulted in improved dissolved oxygen concentrations in the reservoir. However, conclusions of this significance should be based on a run with increased nutrient loadings for a minimum of 10 years before final conclusions can be ascertained as to the long-term health of the system.
