Biotechnical Streambank Stabilization: A Viable Technology in Texas

The Texas Department of Transportation (TxDOT) has commonly utilized concrete and other non-biodegradable measures to stabilize stream channels throughout Texas. While these practices have temporarily solved problems incurred by streambank erosion, evidence indicates a secondary effect occurs downstream and/or upstream of the structure. This secondary effect eventually causes failure of the structure, which not only leads to continual maintenance of the site but could also lead to the retrofitting or eventual replacement of structures.
