Hato (2017) storm tide characters and responses to morphological evolution

Description

This data set include the numerical model simulated storm tide characters of Typhoon Hato (2017) in the 'Bay-Inlet-Channel' system of the Pearl River Estuary, China. The storm tide model was validated by recorded water levels during Hato at five tidal stations. The parameters presented here are the maximum storm tide (MXST), factors' (storm surge, astronomical tide, river flood, and factors' nonlinear interactions) contribution to the MXST, the astronomical tidal range, and the time lag between astronomical tide and storm tide. The responses of the storm tide to morphological evolution were simulated, with two scenarios of before ('Pre-EP' under 1960s geomorphology) and after ('Post-EP' under 2020s geomorphology) large-scale engineering projects, and the Post-EP case represents the validated actual Hato event. In addition, a potential 'Triple Coincidence' disaster was simulated, by adjusting the timing of a flood peak 5 days before Hato to be superimposed on the actual coincidence of peak surge and spring high tide during Hato, exhibiting even higher MXSTs.
