MEASUREMEN AND CONTROL OF EROSION FROM HIGHWAY SLOPES

THE COOSA WATERSHED RESEARCH PROJECT WAS CONDUCTED TO: (1) DETERMINE THE RATE OF AND FACTORS AFFECTING SOIL AND WATER LOSSES FROM HIGHWAY CUTS, AND (2) DETERMINE THE MOST EFFECTIVE TYPES OF PLANT COVER AND THE FERTILITY AND CULTURAL PRACTICES NECESSARY FOR QUICK ESTABLISHMENT AND ADEQUATE MAINTENANCE. THE RUNOFF AND SOIL EROSION FROM EXPERIMENTAL PLOTS ON BARE ROADBANKS OF THE COOSA WATERSHED WERE MEASURED DURING 1960. BANKS WITH NORTHWEST EXPOSURES AND STEEPEST SLOPES ERODED THE MOST SEVERELY. MORE THAN 30 SPECIES OF PLANT COVER WERE TESTED TO CONTROL SOIL LOSS. THE USE OF VARIOUS MULCHES AND APPLICATIONS OF LIME AND FERTILIZER INCREASED THE PLANT GROWTH. NATIVE SPECIES WERE ALSO ENCOURAGED BY LIME AND FERTILIZER. CROWNVETCH HAS 20 POUNDS SEED PER ACRE AND MULCHED WITH 2 TONS OF WHEAT STRAW PER ACRE, HOLDS PROMISE FOR CHECKING ROADBANK EROSION ALONG HIGHWAYS.
