EROSION CONTROL PRODUCT TESTING USING RAINFALL SIMULATION

This report describes the development, design, operation and application of a large droplet, high intensity rainfall simulator. The apparatus generates 6.25 mm droplets and a 10 inch per hour rainstorm randomly dispersed to prevent drilling of the sample surfaces. An 8x12 foot array of generators is used to test a 4x8 foot sloped surface. The report also presents a recommended tests method for evaluating erosion control products and media using the simulator. This method provides accelerated yet realistic erosion forces acting on a simulated highway slope. (FHWA)
