EROSION CONTROL - DESIGN

EROSION OF HIGHWAYS, ROADSIDES, AND CONTIGUOUS LAND AREAS INVOLVES NOT ONLY A STUDY OF THE DESTRUCTION OF THESE AREAS BY SURFACE WATER, WIND, AND TRAFFIC, BUT ALSO A STUDY OF SUBSURFACE WATER AND SOILS CHARACTERISTICS. THE DESIRED OBJECTIVE IS TO HAVE INTENTIONAL PHYSICAL CONTROL, AT ALL TIMES, OF FALLING, SEEPING, AND FLOWING WATER. SPECIFIC CONSIDERATIONS AND SUGGESTIONS RELATED TO THIS CONTROL ARE DISCUSSED UNDER THE TOPICAL HEADINGS: SOIL, STANDARD GUTTER SECTION, CURBING CONTROL, SOIL MAP FACTORS, SUBSURFACE WATER, SOIL ANALYSIS, CONTROL METHODS, WASTEFULNESS OF BACKSLOPE SANDPAPERING, SLOPE GRADING AND TREATMENT, CLASSIFICATION OF OPERATIONS AS TO SEASONAL AND NONSEASONAL, CHECK DAMS, DIVERSION DITCHES, AND GULLY EROSION.
