Understanding hydrodynamics involves the application of complex, state-of-the-art models to predict circulation and the transport of constituents introduced to the aquatic system. Constituents of concern and other important factors may include temperature, salinity, sediments, and pollutants. A variety of models have been developed for use in modeling rivers, lakes and reservoirs, bays, estuaries and the coastal ocean. The models are used to investigate problems related to hydrodynamics, waves, sediment transport, contaminant transport, and/or water quality. Models are coupled together into an integrated framework to streamline their use and application.

Exponent has considerable experience, both technically and in a managerial capacity, to address our clients’ requirements in a professional and cost-effective manner. Exponent personnel are skilled with the development and application of two- and three-dimensional finite element and finite difference models including pre- and post-processing tools and animation routines. For projects of an interdisciplinary nature, we utilize the skills of Exponent’s other practice areas including Environmental Sciences and Geotechnical Engineering.
