Abstract : The investigation reported herein was conducted under Section 32 of the Water Resources Development Act of 1974, Public Law 93-254, entitled 'Streambank Erosion Control Evaluation and Demonstration.' The project was conducted under Work Unit 4 - Research on Soil Stability and Identification of Causes of Streambank Erosion. Work Unit 4 has three tasks: tasks 1 and 2, the Evaluation of Rigid and Flexible Materials for Bank Protection, the subjects of this report; and task 3, the Evaluation of Spray-on Stabilizers for Bank Protection, reported in Investigation Report 1. Expedient surfacing materials were developed at the U.S. Army Engineer Waterways Experiment Station (WES) for use by forward area aircraft as landing surfaces. Several of the materials proved both strong enough to withstand weather extremes. Tests of these rigid and flexible surfacing materials were made at the WES in a hydraulic flume to determine their effectiveness in protecting channel banks against erosion. Banks of the sinuous channel were of sand shaped to slope approximately 1 vertical to 2 horizontal. The area to be protected was located along the outside edge of a curve in the channel, where erosion usually is most severe.
