The navigation channel through the North Passage in Changjiang River Estuary is the doorway for large vessels calling the Port of Shanghai. The channel is relatively shallow with a huge volume of maintenance dredging. In an effort to improve cost-effectiveness of the channel and the dredging works, analysis has been made on the variation behaviour of key stages in relation with dredging and survey works and on the engineering significance and application of such behaviour.The propagation process and deformation characteristics of the tidal waves in Ohangjiang Estuary have been analysized in details, based on the theory of shallow water tidal waves, data of one-year typical tides of 11 tidal stations and morphology. Also described are the general periodical variation and the non-linear variation with time and location, physical machanism and their influence (controlling function) on the variation behaviour of tidal stages at different locations.Results of above analysis indicate that the important hydrological-physical phenomenon, i.e. the water stage "cover" (the tidal hydrodynamic set-up) in this area is the natural results of tidal wave movement, instead of an unreasonable distribution of tidal stages with distance.A new method of "interpolation by hourly tidal wave profile" is proposed to determine the control stage. Also demonstrated is the siginicant controlling function of the North Passage Middle Tidal Station, which has established some kind of operational basis for engineering purpose.

Abstract A stochastic hydrological model with physical concept is set up by the use of the ITO stochastic differential equation. In the simulation of daily streamflow of the Pinshen hydrologic station, the hydrological concept parameter of the model is analyzed and derived by determined method. Thus the simulation of streamflow with hydrological physical concept basis can be realized.

On the basis of grid digital elevation data, the grid flow vector, digital basin and spatial topographical structure were generated for the upper catchment of the Hanzhong hydrological station on the upper Hanjiang River by use of the Digital Elevation Drainage Network Model for river basins. The grid precipitation data after step-by-step interpolation were taken as the input of the Xin′anjiang model for runoff calculation for each grid element. Then, the Muskingum-Cunge method, considering the lateral inflows,...

On the basis of grid digital elevation data, the grid flow vector, digital basin and spatial topographical structure were generated for the upper catchment of the Hanzhong hydrological station on the upper Hanjiang River by use of the Digital Elevation Drainage Network Model for river basins. The grid precipitation data after step-by-step interpolation were taken as the input of the Xin′anjiang model for runoff calculation for each grid element. Then, the Muskingum-Cunge method, considering the lateral inflows, was applied to flood routing on the platform of grid drainage network, and a grid-based hydrological model with high precision was derived. The model is not only able to route the discharge hydrograph for the outlet section of the catchment, but also capable of computing the discharge fluctuation at any grid of different tributaries in the catchment. As a result, the grid-based digital basin coupled with the grid-based hydrological model is of certain theoretical value and practical significance to deepen understanding of hydrological physical mechanism, water resources management, and flood prevention in the catchment.

选取汉江上游汉中水文站以上集水面积为研究区域,基于栅格型数字高程数据,利用数字高程流域水系模型,生成栅格水流流向,构建数字流域水系及空间拓扑关系;然后将逐步插值法处理后的栅格型降雨数据作为研究区内每一栅格单元上的雨量输入,并在各栅格上应用新安江降雨径流模型进行产流计算;再运用考虑区间侧向入流的Muskingum Cunge法在栅格水系上进行"先合后演"的洪水演算,从而获得汉中站的流量过程.结果表明,栅格型水文模型不仅能演算出流域出口断面处的流量过程,还能方便地计算流域内各支流任一栅格点上的流量过程.
