flood section
2.Based on the verification of the mathematical model with water surface, velocity distribution in a section, discharge ratios in the bifurcation reach, distribution of scouring and silting by site measured data, damming of flood water level, variation of velocity distribution in a section, and silting in the borrow areas in the reach before and after the relocation work were calculated.
3.The project mainly solved the problems from the flood control, the morphological diversity of river profile and cross section, and the diversity of habitats in the river through the layout of shoreline and structures, the design of river profile and cross section, the design of riverbank protection, which is one effective engineering practice of Eco-Hydraulic Engineering.
6.This article described the deformation features of Taojiaba landslide and analyzed the inner factors, geologic setting, topography, morphology, stratum, lithology and texture, and the external influence factors, precipitation, flood, human activity, neotectonic activity and earthquake, and the transform features of landslide in the near future, and evaluate stability of landslide through the section coefficient method calculation on basis for landslide mechanism analysis and control work.
7.In this paper, the characteristics of tidal current distribution in Zhapu section of Hangzhou Bay are analyzed and discussed, using the synchronous observed tidal current data obtained from 8 stations of Zhapu section during September, 2000. The results show that in the section, two current cores with a greater speed occur at flood race, the current speed in the southern part is greater than that in the northern part, and the flood current speed is greater than the ebb current speed.
9.Based on the analysis of satellite images of various periods, landform data and river channel transverse section evolution in the lower Yellow River, the characteristics of the river channel boundary condition changes at different location are clarified as middle flood channel flood transport width and area are evidently decreased especially for the main channel with comparison to 1950s, beach area that is unimpeded before become blocked because of road, irrigation channel constructed on it, and consequently intensify high edge of beach and lowering dyke and river.
10.The effect of water flooding is the worst, but injection gas miscible flooding is the best, and GAW more than WAG, depends on effect of displacing oil,By studied section model, (1)in WAG and miscible flood process the water-gas ratio is 1:2, which have better displacement characteristics than the water-gas ratio is 1:1 and 2:1;
