A key area of specialization for our many of our staff, hydraulic modeling is used to evaluate water distribution systems and wastewater collection systems helps clients mitigate existing system problems and plan for future needs.
Our modeling specialists have expertise in evaluation, data collection, data analysis, and model calibration for both steady-state and time-varying conditions. When available, GIS data has been used in conjunction with the hydraulic modeling in order to determine accurate demand estimates and help guide operational strategies. In addition, modeling specialists perform field sampling and water quality modeling in order to provide recommendations to the clients for improving distribution system water quality.
In order to model water quality in both lakes and streams, our staff has used the QUAL-TX water quality model to predict dissolved oxygen concentrations in streams downstream of waste discharge locations for several clients. In cooperation with the TCEQ, models were developed which include all relevant dischargers into the stream, together with appropriate flows and water quality parameters. We then used results of the water quality analyses to determine permit limits for future waste discharges into the streams.
