Tidal bore impact can be strong and destructive, placing estuarine infrastructures under great threat. However, there is a lack of research focusing on accurately estimating the pressure exerted by tidal bores. Herein new experiments were conducted to investigate fronts in glass flume. Through analysis instantaneous three forms bore, it was observed that fluctuation weak breaking characterized pressure. The vertical distribution maximum studied.The appeared around 0.46 times height it. relationship between relative found closely follow normal probability density function. nonlinear regression analysis, an empirical equation derived calculate pressure, which validated using observation data from Qiantang River China. This utilized predict provide valuable support for engineering design.
