Channel stability projects can be challenging because of the dynamics of the system, moving water, and ongoing changes within the watershed. In a sense, these projects are the most difficult because we are attempting to stop a moment in time to make repairs to a system that is always changing.

The historic solution is to use hard armoring techniques including riprap, sheetpile, and concrete to maintain channel consistency. The problem with these methods is they are not very friendly to the natural look of a stream, creek or river. As a result, bioengineering techniques (using plants and other natural materials) have become a popular way to stabilize channels. However, it may be difficult to reproduce the natural system and many bioengineering techniques fail to take root, so there are some challenges in using them in high risk areas.

A recent article in August 2010, Civil Engineering (The Magazine of the American Society of Civil Engineers) on stream restoration projects highlighted the fact that a “common theme within the restoration industry is the idea that projects require a multidisciplinary approach if they are to succeed.” With this in mind, SEH assembles a multi-disciplined team to design and prepare plans and specifications for projects.
