SOIL BIOENGINEERING AND ECOLOGICAL SYSTEMS

The issue of protecting riverbanks in natural and altered streams historically has been a domain of the engineering profession (hydrologic, hydraulic, and geotechnical), the purpose of which is to interpret the statistical data and provide safe and reliable designed solutions at given peak flood occurrences. Slope instability often requires the evaluation of both hydraulic and soil geotechnical parameters. The solutions, depending on the soil profile, range from simple seeding treatments to encourage vegetation reestablishment, to a wide variety of erosion-control blankets and turf-reinforcement mats, to heavy-duty linings such as articulated concrete blocks, rip rap, mattresses, or gabions. Most bank restorations with soil veneer stability include surface vegetative systems, combined with deeper drainage treatments distributed at variable distances. Erosion generated by sliding of large soil masses requires a detailed geotechnical analysis of slope stability. The solution in this case most likely will be a larger structure (retaining wall or mechanically stabilized earth system), depending on the geomorphology of the area. Workshops have proven to be an effective way to analyze the problem of erosion from a more comprehensive perspective, by learning how to integrate geotechnical and hydraulic needs with the environment using the same level of respect, in order to preserve and enhance the stream functions.
