Mapping Hydraulic Zones of Influence and Thermal Plumes: Towards EPA 316 Compliance

Section 316(b) of the Clean Water Act requires that the location, design, construction and capacity of cooling water intake structures reflect the best technology available for minimizing adverse environmental impact. In the context of Section 316(b) of the Clean Water Act, fully detailed, topographically accurate, three-dimensional CFD flow modeling analyses using computational tools like FLOW-3D allow designers, operators and regulators to accurately and reliably gauge cost and environmental aspects of design, modification and build options. In this webinar we demonstrate the ability, suitability and practicality of the three-dimensional free surface modeling software FLOW-3D to accurately capture the long range upstream and downstream hydrodynamic zones of influence associated with cooling water intake structures (CWIS). We also demonstrate the ability of FLOW-3D to accurately map thermal plumes for exhaust flows associated with CWIS structures.
