The Research for the Improvement of Modaomen Outlet of the Pearl River Estuary

本文采用物理模型、数学模型、实测资料分析及遥感技术应用等手段,对珠江口磨刀门口门治理的规划方案进行研究和论证,并据以优选对防洪、潮排、潮灌和航运较为有利的可行方案.

By means of the physical model, mathematical model, the analysis of the field measured data and the applying of the remote-sense technique, we have conducted the research and the demonstration toward the planning of Modaomen outlet of the Pearl River Estuary, and thus determined a reasonable one which would be relatively effective to the flood controll, drainage, irrigation and navigation.Because the Modaomen outlet is vast in area, and there are many inland sea estuaries, waterways and the meeting points of the tidal, the motions of the flow, tide and sediment are quite complicated. So the training engineering might be huge in scale and complex in technique. Therefore, it is necessary to conduct the research with multi-methods and it practically turns to be feasible.The results obtained both by the physical model and mathematical model do basically coincide with each other. The estuary regulations worked out by the analysis of the measured data also agree with the result on the scouring and silting of the estuary analysed by the remote-sense technique. They indicate that the project chosen in following our planning principle to give judicious guidance according to circumstances. They also indicate that the effects to the flood control won't be so heavy after the construction of the engineerings and there won't be unb-enefit against the drainage, irrigation and navigation.
