Services Hydrologic and Hydraulic Modeling and Sediment Transport Studies

Hydrologic and hydraulic analysis involves the assessment of peak discharge rates and flow characteristics of surface water streams for the purpose of flood control; drainage system design; design of hydraulic structures; and the assessment of baseline conditions, opportunities, and constraints for projects associated with watercoursesSince most watercourses have earthen bed or banks, sediment transport analysis is fundamental to understanding erosion, deposition, scour, and long-term morphological trends in stream channelsAspen Consulting Engineers, a division of Aspen Environmental Group, is highly qualified to perform studies in these areas as illustrated by our staff's extensive experience in hydrologic, hydraulic, and sediment transport modeling for a variety of clients in the southwestern U.S.
