Water Quality Modeling
Water Quality Modeling of Lake Dunlap (New Braunfels Utilities), New Braunfels, Texas. HEI Staff is currently the project manager for EC for New Braunfels Utilities (NBU) to conduct an eighteen month water quality sampling project. The scope of the project is to collect surface water samples in order to obtain information to assist in determining whether nutrient limitations on point source discharges from NBU’s wastewater treatment plants (WWTPs) will prevent the growth of excessive aquatic vegetation in receiving waters, as provided by the Texas Commission on Environmental Quality (TCEQ) regulations at 30 TAC 307.4(e). As part of the water quality study numerous water quality studies related to point and non-point source loadings entering Lake Dunlap from the Comal and Guadalupe were evaluated to determine the impact of point and non-point source nutrient loadings on Lake Dunlap.
Water Quality Modeling, The Tidelands, Port O’Connor, Texas. HEI staff completed a water quality study of a proposed subdivision located northwest of Port O’ Connor, Texas. Modeling of the subdivision was done to ensure adequate dissolved oxygen levels in the far reaches of the subdivision. Parameters included sediment oxygen demand, aerations, dispersion, biochemical oxygen demand, tides, meteorological factors, surface water runoff, temperature, etc.
Water Quality Modeling, Beachside Development, Seadrift, Texas. HEI staff completed a water quality study of a proposed subdivision located along San Antonio Bay, Texas. Modeling of the subdivision was done to ensure adequate dissolved oxygen levels in the far reaches of the subdivision. Parameters included biochemical oxygen demand, tides, meteorological factors, benthic demand, surface water runoff, temperature, etc.
Water Quality Modeling, The Sanctuary, Port O’Connor, Texas. HEI staff completed a water quality study of a proposed subdivision located along Matagorda Bay, Texas. Modeling of the subdivision was done to ensure adequate dissolved oxygen levels in the far reaches of the subdivision. Parameters included biochemical oxygen demand, tides, meteorological factors, benthic demand, surface water runoff, temperature, etc.
Water Quality Modeling, Seadrift, Texas. Dr. V. Harkins was project manager for a water quality model of a proposed subdivision near Seadrift, Texas located along Espiritu Santo Bay. Initial data collection was completed for model development including biochemical oxygen demand, tides, meteorological factors, benthic demand, surface water runoff, temperature, etc. Alternatives for subdivision design were completed with related water quality effects being addressed.
Tarrant Regional Water District on the Lake Palestine Integrated Pipeline Project, a joint TRWD-Dallas water transmission system to convey water supplies from Lake Palestine, Cedar Creek Reservoir, and Richland Chambers Reservoir to locations in the TRWD and Dallas Service area: Dr. Harkins is currently serving as the field project manager for the water quality sampling and data for treatability analysis to determine impacts of blending raw waters from and into reservoirs being evaluated in the project which include: Eagle Mountain, Benbrook, Arlington, Richland Chambers, Joe Pool, and Cedar Creek.
