Hydrologic Engineering Expertise

Collapse All Expand All
Hydraulic/Civil Engineers, Geologist, Engineering Technicians and Student Trainees with more than 80 years of combined experience in the fields of sedimentation, channel stabilization, navigation, field data collection and environmental restoration projects.
The District team provides floodplain management information, technical service and planning guidance on flooding and floodplain issues providing complete, accurate and timely information on these issues.  Their extensive capabilities include hydraulic modeling, nonstructural flood mitigation assessments and acute knowledge of the National Flood Insurance Program to provide city, county, regional, and state entities with expert advice on all facets of flood risk reduction and floodplain management.
The District's experts for conducting hydraulic engineering design and analysis related to water resources for Civil Works, Military and HTRW projects throughout the Omaha District and worldwide. Technical capabilities include 1-D and 2-D hydraulic modeling and assessing hydrologic safety of dams, as well as the hydraulic design and review of flood risk reduction measures including open channels and conduits, hydraulic structures, erosion protection measures and emergency mitigation measures.
The District’s consultant for hydrology related issues has a diverse workload with a portfolio of projects throughout the Omaha District and around the world.  Examples include: precipitation/ runoff modeling, reservoir-operation modeling, planning studies related to water supply (agricultural, municipal, etc.), wetland rehabilitation, interior drainage (culverts, pumping stations, etc.) and Missouri River recovery.  Personnel also assist during flood emergencies by providing critical forecasting and site-reconnaissance information.
Corps water control projects (dams, local protection, levee systems, and navigation projects) store, regulate, divert, constrict or convey most of the surface waters in the United States. As stewards of a significant percentage of the nation’s aquatic environment, the Corps has a responsibility to preserve, protect and, where necessary, restore that portion of the environment altered by Corps projects.
The Corps water quality program is committed to holistic watershed ecosystem based resource management requiring understanding the interactions of the uses and users of the aquatic environment and the impact of Corps structures and their operation on the aquatic environment. The water quality program provides one of the greatest opportunities for the Corps to demonstrate its commitment to environmental leadership, conservation, restoration and stewardship. By planning, designing, constructing and operating water projects in a manner that achieves project purposes while preserving, protecting and restoring the ecological integrity of the aquatic resources, the Corps can demonstrate its leadership role in responsible environmental engineering.
