In this paper, experimental confirmations of our approximate nonlinear theory on the shallow water waves which was previously published are reported. The results obtained are as follows : In the range of ω<3 ω₀ (ω is the frequency of oscillations of the tank containing the shallow water and ω₀ is the natural frequency of the water), the theory sufficiently well represents the wave motions as well as the pressure relation that the bottom pressure exerted from the waves is equal to the static water pressure. The bore and the standing wave appear almost precisely at ω=ω₀ and ω=2 ω₀ respectively. The existence of the special combinations of horizontal and inclining oscillations of the tank where no wave motion is excited is also proved experimentally. At higher resonances of ω=3 ω₀, 5 ω⁰ etc., wave motions are very complicated and appear to include the subharmonics having the frequencies such as 1/3ω=ω₀ for ω=3 ω₀, 1/5ω=ω₀ and 3/5ω=3 ω₀ for ω=5 ω₀ and so on, respectively. This phenomenon can not be derived from our simple theory. We became recently aware of Chester's elaborate works on the same subject as ours (he deals with the horizontal oscillation only), so we could not learn from him to our great regret.
