MWMO Watershed Bulletin 2010-3
The Mississippi Watershed Management Organization (MWMO) has developed a guidance document and planning software for bank restoration on large river systems.
Physical characteristics of the riverbank, along with predicted shear stresses across a full range of flows, are used to classify and recommend bio-engineering applications that restore and protect the riverbanks of the Mississippi River.
This effort included: writing an installation manual, field surveys and data collection, modeling, and data synthesis. Field surveys were conducted to collect information on bank profiles and slope, vegetative cover, soil type, and existing structures or protection measures. Two-dimensional hydrodynamic modeling of the Mississippi River from the Hwy 694 bridge to Ford Dam has been conducted to assess shear stress and critical bank elevations. Planning software was also developed to allow property owners to select locations, review physical data and modeling results, and choose applicable bio-engineering options for their site.
The MWMO anticipates further development and application of this tool, in cooperation with local and state authorities, as a planning resource other organizations can replicate and utilize for TMDLs and Implementation Plans.
