通过对比曹妃甸工业区建设前后的水下地形变化，可以了解其水沙运移规律和冲淤演变趋势，进而评价滩槽的稳定性及其对工程的响应。2006年和2012年的水深测量显示，曹妃甸深槽稳定性良好，在建设方案完成后，人工疏浚引起的地形下切幅度较大，范围分布在一号港池及周边、甸头深槽局部和东南海底拐点北侧海域。疏浚施工起动的海底泥沙作为主要泥沙来源，和自然冲刷来沙一起淤积在周边或沿岸海域，其中甸头东侧岸坡的少量泥沙向西沿岸输送并落淤在沿途，甸头西侧岸坡的泥沙主要堆积在一号港池西南侧防波堤根部。

By comparing the change of underwater topography before and after reclamation of Caofeidian indus-trial zone, the sediment movement and erosion-deposition evolution can be studied, and the shallow-channel stabili-ty and response to project can be evaluated. Bathymetry results in 2006 and 2012 show that the deep channel is in good stability. After the completion of construction, the seafloor cut down greatly caused by artificial dredging, the range covers Harbor No.1 and its surrounding sea area, some local area in front of the headland, and the north sea area in front of the southeast seawall inflection point. As the main sediments source, sediments start by disturbance of dredging together with sediments eroded naturally, deposit near the dredging area and in the coastal area. Among them, a little sediments in the east slope transport to southwest along shore and deposit in the way, sediments in the west slope mainly accumulate in the root of breakwater of Harbor No.1.
