Abstract
    In this paper the effects of topographic forcing on the hydrography of Laizhou Bay, imposed by the huge sediment supply of the Huanghe River, is investigated. Particular attention is given to the temporal evolution of various parameters characterizing the M2 tide, especially the mean largest tidal range (MLTR), the mean highest high water (MHHW), the mean lowest low water (MLLW), and the mean sea level (MSL). Numerical simulations and statistical analyses of tidal records show that water levels have increased in general, causing tidal ranges and mean sea level to increase, coupled with a delay in the tidal phase by as much as 1.3 hours. The rapidly changing hydrographic situation urgently calls for a reconsideration of engineering sign standards coast in order to mitigate the effects of extreme events along the coast. Thus, the currently assumed 50-year return period should be replaced by a 20 year return period.
