Abstract

Abstract:

The Lingdingyang Bay-Humen outlet-tidal channel of the Pearl River is a typical geomorphic structure in the networks-bay system of the Pearl River Estuary. Tidal wave propagation in the channel is significantly influenced by the channel convergence in the estuary, the conversion effect at Humen outlet, the divergence of the tidal channel, and the riverbed friction. Thus, the spatio-temporal variation of the tidal regime is rather complex. Based on the daily high and low tidal levels from gauging stations along thetidal channel from 1990 to 2016, tidal amplitude gradient and wave celerity of different tidal constituents are computed using harmonic constants (i.e., tidal amplitude and phase of different tidal constituents) extracted from a standard harmonic analysis, and tidal wave propagation characteristics are investigated. The results show that the annual increase in amplitude and wave celerity gradients of the diurnal constituents (the amplitude gradients of K₁ and O₁ being 9% and 18%, respectively; both wave celerity being 1.4%) in Lingdingyang Bay were larger than those of the semi-diurnal tides (the amplitude gradients of M₂and S₂ being 3% and 6%, respectively; both the wave celerity being 1%). The tidal waves changed abruptly due to the substantial variation in morphology. The change-points of the tidal wave celerity in Lingdingyang Bay and tidal channel were in 2009 and 2000, respectively. The relationship between wave celerity and tidal amplitude gradient changed considerably after the abrupt change.

Key words: tide-dominated estuar, harmonic analysis, wave celerity, amplitude gradient, abrupt change
