The Deadman’s Run Tributary, located in Lincoln, Nebraska, was deeply incised. This resulted in widespread bank erosion, damaging and threatening utilities and valuable property on the University of Nebraska campus. Intuition & Logic and Schemmer Associates, Inc. worked together to provide analysis and channel restoration design.  

 

The final design includes relocating half of the previously straightened channel back into its floodplain and restoring a natural sinuous channel form. The restored channel slope, sinuosity, riffle pool spacing, bend radius, amplitude, section shape, low flow channel and floodplain were designed to match the natural geomorphic stream geometry.

 

 

 

The upper channel was raised to it’s previous elevation before the incision occured. Rock grade control structures and vegetated revetment bank stabilization were used stabilize the stream.  Revetment designs incorporated plants that are capable of reinforcing soil under high stress conditions.
