Stream Restoration in the Arid Southwest

Natural Channel Design, Inc. (NCD) is a consulting firm providing services in natural resource planning and river engineering. NCD specializes in training, research, assessment, and design of natural resource planning efforts. The firm conducts research on stream systems and provides leadership in the assessment and restoration design of natural stream channels. Effective stream workshops are offered regularly with emphasis on inventory, assessment and design of natural stream channels. 

NCD has extensive experience in geomorphology, hydrology, hydraulics, drainage, erosion control, irrigation, wetland delineation, stream bank stabilization, and enhancement of natural stream channels and has applied that expertise to design and permitting of projects for federal and state agencies, tribal entities, municipalities, and private owners.

The geomorphic or natural channel approach is based on 40 years of empirical work by Luna Leopold and others and includes the stream classification and assessment techniques developed by David Rosgen. The approach seeks to assess and restore stream channels by moving them toward their potential stable form. Bioengineering practices utilizing native plant and structural materials are extensively incorporated in restoration design.
