Dynamic Solutions-International, LLC (DSI) is an environmental science and engineering firm founded in 1998 in the USA.  We offer a range of water resource engineering, computer modeling, environmental, scientific, and data management services needed for resolving complex water resource problems. We maintain a strong representation in the disciplines of civil, hydrologic/hydraulic, coastal and environmental engineering; hydrologic, hydraulic, hydrodynamic, sediment transport and water quality modeling; data management and statistics; geographic information systems (GIS), and computer programming. In addition to excellent technical engineering and numerical modeling credentials, DSI's staff have a thorough understanding of applicable environmental regulations, data collection and processing methods, and database/software development methods. We specialize in development of innovative applications of 1, 2, and 3-dimensional hydrologic, hydraulic, hydrodynamic, sediment transport, groundwater flow and transport, and water quality computer models, including EFDC_Explorer. In addition, we are experienced in using geographic information systems (including ESRI ArcGIS) as the integration platform for watershed and environmental assessments.

Our staff have managed, planned, and conducted water resource studies in rivers, streams, lakes, reservoirs, estuary and coastal environments in North America, Southeast Asia, Australia and Europe. DSI has designed focused hydrologic and hydraulic data collection and monitoring programs, developed protocols for properly performing field studies, and performed terrestrial and aquatic investigations to provide defensible data for federal, state, and local government agencies as well as private industrial and legal firms.
