This research is mainly the sand dynamic state that inquires into the nearby waters of Taipei port to distribute, by having already imitated harbor current conditions in Taipei port, and is done ratio by the actual data to and correct, respond harbor future development in Taipei port and follow-up project, brings the influence of the Danshui river estuarine evolution river a nearby waters by this extension that understands Taipei port.
The main simulation model is the littoral sediment module (LITDRIFT) developed from Danish Hydraulic Institute(DHI). In the every project in Taipei port of project the sea area will cut Twenty-eight sections. The littoral sediment module is based on wave energy conservation equation. Use this model and consider the wind, waves, bed resistance, eddy viscosity. And is done ratio by the actual data to and correct for the simulation of sand drift of coastline cross section. The coastline evolution model(LITLINE) is base sand drift transmission quantity continual equation main equation, carries on the value calculation, position of the simulation coastline vicissitude.
By the results of the numerical modeling, we discover along with project carrying on, north the Taipei port the breakwater seacoast of by the north to the Danshui river mouth, because the coast sand drift the granulated substance and the embankment groiu effect, will have the obvious silt deposit, seriously will occur in the Danshui river mouth estuary place. By the entire year observation, summer mostly presents silts up, the winter presents the corrosion.
