Anthropogenic Influences on the Hydrodynamic and Tidal Discharge in Tongzhou Bay, Nantong, China

Abstract In this study, we determined the variations of tidal flow field and prism caused by human activities in Tongzhou bay using MIKE 21 hydrodynamic model as analyzing tool. After activities, sea area alongshore engineering is changed, most obvious changes can reach over 0.1m/s; discharge decreases land accretion leading to shrink Nantong near-shore waters, there up 12% reduction after planned reclamation during one spring tide period.
