Abstract : The program described in this report is the second phase in the development of a polymer-based silt-stabilization system. During this program several algin resins gelling agents, and filler materials were evaluated in laboratory beaker experiments; the most promising of these were then evaluated in a test tank. Test-tank experiments were made with especially designed equipment. An important aspect of the work was the development of a method and equipment capable of dispensing and gelling the polymer so that a continuous and coherent film could be obtained. The experimental equipment designed for test-tank evaluation was capable of laying a film about 1 foot wide. After a number of experimental runs were made in the test tank, a basic material system was selected. Simplified application equipment for field experiments was then designed. This application equipment consisted of (1) a 3-foot-wide nozzle, (2) 50-foot hoses, (3) a gasoline-engine-powered polymer and gelling-agent pumping and storage system. These equipments were successfully operated in the test tank. Based on the results of this development work, recommendations were made for further detail investigation of the required operational qualities of the material system, field tests of the application equipment, development of field-application techniques, and development of a larger scale application system.
