The design and construction of a small wave-sediment tank, built and instrumented for under $10,000, is described. The tank is equipped with a piston-type wavemaker, capable of producing both small-amplitude and solitary waves. The middle section of the tank contains a sediment bed appropriate for wave-soil-structure interaction and sediment transport experiments. Wave energy is absorbed by a gravel beach located at the opposite end of the tank from the wavemaker. Instrumentation includes three eapacitive wave height gauges. The wavemaker is controlled by a desktop computer, which also provides data-logging capability. Applications of this wave-sediment tank to research into grounded ship migration and barge added-mass are presented.
