The Study of Environmental Characteristic by Coastal Engineering in Rock Coast
In order to study the evolvement of rock coastal in Hebei Province, the data was taken to study the evolved stations, such as relief maps, charts, remote sensing imagines and the field data of different areas from 1956 to 2007.With 3 S technology, it analyzed the evolvement processing and reasons of the rock coast by construction of coastal engineering in half century.The results were shown that it was changed strongly by the station from 1979 to 2007 when the station stopped the littoral current caused by coastal engineering such as Qinhuandgao Port and Shanhaiguan Shipyard.As the result, the section was deposited in the east of Qinhuangdao Port while eroded in the west.And the highest erosion speed was 2.49 m/a in the section from Xinkaihe River to South Mountain shipside.The angle was about 60°~80° from between middle bay and east bay.By the transport yield reduce of Tanghe River and Chituhe River, the coastline was eroded by NNE and ENE waves.Without the supply of sediment from the east bay and middle bay where were eroded seriously, the erosion speed was above 3.26 m/a, and the section was eroded fast with the speed of 3.67 m/a between Jinshan Mountain and Tiger Stone in west bay.
