Cooling Water Intake Structures (CWIS) have the potential to disrupt river and reservoir habitats. FLOW-3D allows engineers to accurately evaluate upstream and downstream Hydraulic Zones of Influence (HZI) for different design options. With the recent publication of the EPA’s final rule on section 316 (b) of the Clean Water Act, accurately modeling the hydraulic zones of influence and thermal plumes associated with power plants using CWIS has become a major tool in helping plant owners gain compliance with section 316(b) of the Clean Water Act.
FLOW-3D‘s scalar release and particle tracking models, coupled with its fully-validated open channel hydraulic solvers allow engineers, environmental scientists, owners and regulators to gain invaluable, precise insights into the entrainment rates of upstream species alongside their exposure to the plant’s thermal outflow signatures.
- Detailed, fully three dimensional modeling of hydraulic zones of influence
- Tracking of multiple species spatio-temporal evolution and fate using FLOW-3D‘s particle model
- Evolution of multiple contaminants using the scalar transport model
- Fully three dimensional flow solutions both in the near and far field
- State-of-the-art k-omega turbulence modeling for thermal and momentum driven jet flows to accurately capture thermal plumes near range structures
