EROSION CONTROL CRITERIA FOR DRAINAGE CHANNELS, DRAFT

TEMPORARY, ARTIFICIAL LININGS TO BE USED TO PREVENT EROSION IN DRAINAGE CHANNELS UNTIL VEGETATION CAN BE ESTABLISHED ARE ANALYZED. A VARIETY OF LINER MATERIALS WERE TESTED ON A SERIES OF TEN TEST SOILS. LINERS INCLUDED EROSIONET, JUTE MESH, FIBERGLAS MATS, EXCELSIOR MATS, STRANDED FIBERGLAS, STRAW, AND GRAVEL. LOOSE MATERIALS REQUIRED A COVER OF MESH PINNED TO THE CHANNEL. BARE SOIL CHANNELS AND CHANNELS WITH A GROWTH OF 2-1/2 INCH BERMUDA GRASS WERE ALSO STUDIED. CHANNEL CAPACITY INFORMATION IS PRESENTED IN THE FORM OF STATISTICALLY DERIVED EQUATIONS AND GRAPHS FOR EACH LINER RELATING VELOCITY, HYDRAULIC RADIUS, AND SLOPE. EROSION RESISTANCE IS EXPRESSED IN TERMS OF THE MAXIMUM PERMISSIBLE DEPTH OF FLOW AS A FUNCTION OF SLOPE FOR EACH LINER. A RANGE OF VALUES IS PRESENTED BASED SUBJECTIVELY ON THE RELATIVE SOIL EROSION RESISTANCE. THE GOOD CORRELATION BETWEEN RESULTS OF THIS STUDY AND OTHER STUDIES CONCERNING SHORT BERMUDA GRASS PERMITS APPLICATION OF THE PROCEDURES OF THIS REPORT TO OTHER VEGETATIVE LININGS. COMPREHENSIVE DESIGN EXAMPLES ARE INCLUDED. /BPR/
