Hydrologic and Hydraulic Modeling

“All models are wrong some are useful” –George Box

Accurate hydrologic and hydraulic modeling is important in understanding and visualizing the huge range of flows that shape ecosystems, flow through stormwater systems, and fill floodplains. Modeling can become an end in itself when not designed to answer a specific question. We understand the limits and useful application of models in planning and design. Our modeling work ranges from detailed site specific design models to watershed wide basin planning scale models, to pilot scale models that compare outcomes of various policies. We are familiar with design storm and continuous simulation hydrology, steady and unsteady flow, one and two dimensional modeling, and sediment transport modeling and have used all of these for various projects.
