Description	Erosion Control Materials Design Software (ECMDS) provides computer assisted selection of materials for slope erosion protection and channel scour resistance. It is based on laboratory and field research involving erosion control blankets, turf reinforcement mattings, vegetation and riprap utilizing design procedures developed by the United States Department of Agriculture and Federal Highway Administration. English or System International (metric) units may be selected for input parameters and output data. Output from individual analysis may be saved to files for future reference and editing. The Slope Protection mode takes into consideration site parameters including slope gradient, slope length, soil type and erodibility, vegetation type and density, and regional precipitation distribution data, for analyzing a proposed material(s) performance on a specified slope. Dependable soil-loss calculations are obtained through procedures and equations of the Revised Universal Soil Loss Equation (RUSLE) for material evaluation and sediment control analysis. Erosion control materials include all North American Green erosion blankets, new vegetation, new vegetation/blanket composite, mature vegetation, and C350/P300 reinforced mature vegetation. The Channel Protection Design Mode operates on the Federal Highway Administration's HEC #15 Tractive Force Procedure and the USDA's AG HBK #667 Design Method for Grass-Lined Open Channels. It determines channel hydraulics and stability analysis of lining materials such as North American Green erosion blankets, vegetation and riprap in both straight and curved channel reaches. Includes a procedure for designing geosynthetically reinforced turf channel linings. Once suitable product(s) are determined the program provides material specifications in a variety of formats. Standard material, C.S.I., Performance, and Project specifications are included in accessible text files for viewing, printing, and in some cases editing for inclusion in complete project specifications. The program can also be used to determine suitable vegetation species for a project site. The program uses information on location, soil types, moisture regimes, and planned maintenance of a project site to provide a list of adapted grasses and legumes with corresponding seeding rates. Available in English and Spanish.
