Abstract : An investigation was conducted on a 1:12-scale hydraulic model to obtain data for the optimum design of cover layers for protection of railroad relocation fills at the Ice Harbor and John Day Lock and Dam projects from wave action. The cover layers are to be composed of locally available riprap and gravel. Tests were also conducted on a 1:20-scale hydraulic model to obtain information concerning wave runup and rundown on riprap-protected fill slopes. (Author)
