ABSTRACT:
A structure which inhibits erosion of a hillside having a grade includes an upwardly open trough extending down the grade of the hillside, the trough having lateral skirts buried in the hillside to a depth below the lowermost trough depth measured transversely. The skirts and the trough are impervious to water and sealed together in watertight fashion and the trough forms a channel which is transversely lowermost in a valley extending down the grade of the hillside. The valley has sidewalls which slope gently toward the trough and are covered with sod. Runoff is directed by the valley to the trough in noneroding manner and the trough conducts runoff down the hillside.
