Exponent’s Water Resources team specializes in the application of proven hydrologic, hydraulic, hydrodynamic, and sediment transport research and science to provide scientifically sound and cost-effective solutions to our clients. Complex problems of an interdisciplinary nature are addressed through close interaction with Exponent’s other practices.
Our staff bring a high level of expertise with an array of modeling tools and analysis techniques. We routinely use accepted and appropriate one-, two-, and three-dimensional models for simulating flow and transport, supplemented with focused field and laboratory investigations, geographic information systems, pre and post-processing tools, and visualization and animation routines. We determine the appropriate approach for modeling and analysis, and often custom-tailor software packages to meet our clients’ specific needs.
