Book Description
This investigation clearly indicated the advantages of using spray-on stabilizers on denuded slopes until vegetation becomes established. Three of the materials tested, Aerospray-70, Soil Seal, and DLR, were effective in establishing vegetation. These materials showed no adverse effect on germination. Bermuda grass in these sections emerged and propagated better than that in the control plot. Aerospray-70 and Soil Seal were the most effective in controlling soil erosion during the test period. The plant emergence and growth rate using Peneprime and Nerozin were below that obtained in the control plot. In conclusion, it is recommended that Aerospray-70 and Soil Seal be incorporated into some of the Section 32 Program demonstration projects for field testing. It is also recommended that spray-on stabilizers be considered for general use to inhibit erosion while enhancing plant emergence and early growth. General guidelines for application of spray-on stabilizers are given in Appendix A; further studies on various types of soils subject to different conditions may show more effective application procedures.

Book Description
Tests were conducted at the U. S. Army Engineer Waterways Experiment Station (WES) on aluminum grids to determine the suitability of these materials as a potential bank protection system. Specifically, this test examined a grid/vegetation system in combination as a possible means for controlling bank erosion. The system was evaluated for effectiveness and durability in controlling erosion, ease of placement, and cost. It was envisioned that this system might be employed where something more durable than vegetation, but less durable than riprap, is believed necessary. The test area with the aluminum grid and rye grass growing in the areas surrounded by the hexagonal cells experienced very little or no erosion. The test area with rye grass (only) growing experienced some erosion, while the area adjacent to the test area experienced severe erosion.

Book Description
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.
