Introduction,dge and technically advanced. The practice of bioengineering or biostabilization has been around a long time. While remaining rooted in tradition and empirical performance, the field has evolved to incorporate modern construction materials, improved science related to design specifications, and broa

Project #1: Fleming Creekbor, Superior, Northfield, and the City of Ann Arbor. Fleming Creek runs through the Parker Mill County Park and once provided motive power for that mill. It also flows through the University of Michigan, Matthaei Botanical Gardens. The stream bank remediation site is located adjacent a walking trai

Project #4: River Landingischarge at the site of 3,330 cfs (1968). Dams immediately upstream and downstream of the site tend to regulate flow and suppress peaks in this reach of stream. The river is also quite wide at the site which tends to decrease velocity and depth of flow.

Project #5: Nichols Driveank lies at the base of a steep glacial moraine. The Huron River has a drainage area of 730 sq. miles, a daily mean stream flow of 380 cfs, and a maximum recorded peak discharge at the site of 3,330 cfs (1968). Dams upstream and downstream of the site now tend to regulate flow and suppress peaks in

Project #12: Geyserville in the river vary seasonally, attaining values as high as 10,000 cfs during winter floods. The soils at the site consist of riverbed alluvium and floodplain deposits. These soils are well drained and not subject to ponding. They are mainly cohesion-less and vulnerable to erosion and scour.
