Surface wave erosion laboratory tests were performed in hydraulic wave flume on materials shipped from Yakima Project, Wash, to determine cover blanket needed to prevent leaching of fine base material; most stable cover blanket was formed by screening talus material on 3/4 in. screen; minus 3/4 in. material was placed over base material with plus 3/4 in. material on surface; tests were recorded by motion pictures.
