An Algorithm for Simulating Intertidal Flood Area Based on Digital Tide-Coordinated Shoreline

An algorithm is presented for simulating the intertidal flooded areas based on digital tide-coordinated shoreline(DTS).On the basis of creating digital intertidal zone model(DIZM) and instantaneous water surface model(IWSM),DTSs are acquired.Disconnect depressions are determined depending on types of DTS,and influencing areas of them are computed efficiently.Moreover,reasonable rendering modes of DIZM and IWSM are determined,and flooded areas are built and displayed correctly.Experimental results demonstrate that the proposed algorithm is more advantageous than traditional algorithms in accuracy and efficiency.
