One of the only two testing facilities in the Philippines that could supplement coastal engineering research is a 9-m long by 60-cm wide by 45-cm deep wave flume that uses a top-hinged, paddle-type wave generator powered by a rotating motor. It will be retrofitted by replacing the wave generator and extending it to allow longer waves to propagate. In this paper, we designed the new wave generator utilizing planar wavemaker and linear wave theories. We determined the maximum properties of the waves that can be generated given the physical limitations of the flume. The final design of the wave flume includes its extension to 22-meter length and a bottom-hinged, flap-type wave generator powered by a pneumatic cylinder attached to the top of a 0.5-meter length paddle. A maximum stroke of 0.5 meter at 25-cm deep still water level was set. Theoretically, it can generate model waves with heights up to 12.8 cm and period of 2.1 seconds. This new wave flume could jumpstart physical modelling studies in the country and be used by other local universities as basis in constructing their own wave flume for instruction and research.
