Abstract

Using the single-point ground wave (GW) radar data at Shensi Station and the water level data at three stations (Shengsi, Luchaogang and Daishan), the authors obtained the flow vectors from the radial velocity of GW radar observation, and calculate four sub-tidal harmonic constants (O1, K1, M2 and S2). The tidal characteristics derived from the GW radar dataset agreed well with those from the tidal gauge data. The authors also analyzed the tidal energy flux and tidal energy dissipation rate. There was a good relationship between the tidal energy dissipation rate and topography. The study showed a good way to calculate tidal energy dissipation rate using GW radar data.
