Steady-Flow Stability Tests of Navigation Opening Structures, Hilo Harbor, Tsunami Barrier, Hilo, Hawaii. Hydraulic Model Investigation.
Abstract
Steady-flow tests of navigation opening structures in the Hilo Harbor tsunami barrier were conducted to determine the effect of tsunami-induced high-velocity currents through the navigation opening on stability of the barrier heads. Tests were conducted in a 1:60-scale model which reproduced one-half of the navigation opening and a 1:72-scale model which reproduced the full opening. Steady flow through the opening with a head differential of 28 ft across the barrier was the basic test flow, representing the peak flow condition caused by the design tsunami. Tests were designed to determine the cover-stone size required on the barrier heads for stability under this steady-flow condition and also to investigate methods for providing toe protection for barrier heads constructed on sand. Results of the steady-flow tests were to be correlated with results of model tests concerned with wave action and with factors to develop the optimum design of the tsunami barrier. (Author)
