一、前言潮波从大洋传入内海,潮振幅明显增加。这一潮波再进入河口区段,由于河口的地形不同,潮波的变化有很大的差异,如呈喇叭形状的河口段,由于地形效应,潮波能量逐渐集中,所以进入河口的潮波在传播过程中,振幅逐渐增大。而非喇叭形状的河口区,湖波进入河口段后,由于波能量耗散,湖波在向上游传播过程中,振幅逐渐减小。 I. Preface Tidal waves are introduced into the inner sea from the ocean. The amplitude of the tide is obviously increased. Due to the different topography of the estuary, there are great differences in the tide waves. For example, in the estuary section with a trumpet shape, due to the topographic effect, the energy of the tidal wave is gradually concentrated, so the tide waves entering the estuary In the dissemination process, the amplitude gradually increased. However, when the lacustrine wave enters the estuarine zone, the amplitudes of the lacustrine wave gradually decrease due to the dissipation of the wave energy.
