Streambank Stabilization Selection

Emelia Brooks, Lizzie Hickman, Leslie Ogar



John Redmond Reservoir, a drinking water supply reservoir in eastern Kansas on the Neosho River, has lost about 52% of its storage volume due to sedimentation, from an original capacity of 82,000 ac-ft. The sedimentation rate is estimated at about 740 ac-ft/yr. Though the USACE is planning to dredge the reservoir in 2015 in order to return it to its former capacity, it is crucial that this valuable freshwater source retains its full capacity in future years, as dredging of an inland lake is a costly and inconvenient solution which is not viable as a preferred method of reservoir maintenance against volume reduction. The US Army Corps of Engineers (USACE) Tulsa Office has tasked Hybrid Stream Solutions with devising methods to reduce sedimentation in John Redmond Reservoir in order to prolong its life. The greatest source of these sediment loads in the river is erosion from upstream banks, from the watershed area which drains into the reservoir, rather than from overland runoff from agricultural fields or urban areas. The Neosho River is the largest stream in this area. Therefore, the most direct way to solve this problem is through stabilization of Neosho River streambanks against fluvial erosion and mass wasting.



Problem Statement

Hybrid Stream Solutions’ task is to create watershed-specific guidelines for innovative, cost-effective designs most effectively reduce sedimentation in John Redmond Reservoir to prolong the life of the reservoir.

Scope of Work

The scope of work for this project includes: planning; case study site selection; characterization of physical parameters of the stream and streambanks, both through literature and database review and physical and field testing done by the team; extensive literature review and analysis of streambank stabilization methods already in accepted use, including possible patent conflicts; review of federal (especially USACE) guidelines for streambank stabilization; creation of a computer tool by which to judge the applicability of current methods to the sites in question; the design or modification of methods or combinations of methods; and validation of optimum methods through the use of the Bank Stability and Toe Erosion Model (BSTEM). Not included in the scope of this work is the actual restoration or construction of stabilized streambanks at the chosen case study sites on the Neosho River.
