Services & Experience:
- Sediment Sources and Budgets
NHC identifies and quantifies sediment sources to analyze sediment transport and budgets. This helps address concerns with reservoir sedimentation, water quality, and multi-objective management options.
- Stream Morphology and Processes
Our experts assist in designing stable channels, determining scour and erosion potential, and formulating restoration plans. Services include investigating and classifying stream morphology, evaluating stream stability and processes, analyzing historical trends, and geomorphic mapping.
- Erosion Studies
Potential hazards associated with bank erosion, flooding, or channel shifting are identified. Studies are typically performed for the design of bridges, highways, flood control levees, water intakes, and other river engineering facilities.
- Restoration Studies
We examine the effects of channel and floodplain morphology, and processes on aquatic and riparian habitats. Restoration concepts can be developed that incorporate geomorphic principals.
- River Evolution Studies
Our work can predict future watershed and stream conditions based on integrating historical conditions, sediment budget, stream analysis, and other geomorphic studies.
- Depth of Experience
Since 1972, NHC has conducted geomorphic studies contributing to many design, management, and restoration projects in North America, Asia, and Latin America. North American clients have included federal, state/provincial, county/regional district, and city governments, as well as watershed conservation groups and private companies. Overseas clients have also included national governments, banks, and international agencies.
