1 A German rendering of a Serbo-Croat term referring to the terrain created by limestone solution and characterized by a virtual absence of surface drainage, a series of surface hollows, depressions and fissures, collapse structures, and an extensive subterranean drainage network. 2 A type of topography that is formed on limestone, gypsum, and other rocks by dissolution, and that is characterized by sinkholes, caves, and underground drainage.

For the experimental results under the steady flow conditions, the scour hole and local scourdepth are comparatively small for both a eccentric and concentric non-uniform piers.Since the scouring retardation by the top of foundation and the distance between thetop of foundation and the initial bed level, the downflow intensity is reduced for theun-exposed bridge foundation (Y=+10mm).
研究结果显示於定流量作用下,不论是非同心圆或同心圆不均匀桥墩,当桥墩基础未裸露(Y=+10mm)时,由於覆土高与不均匀面之影响,而减缓向下射流之强度,因此所产生之冲刷坑大小及冲刷深度较小。

The flow .structure and river bed deformation near piers when an angle exists between the trend of piers and the direction of main-flow will be different from those when the angle equal to zero, such as the flow-obstructing width will increase, the diversion function will occur, the partial scouring pits get larger and deeper, and the main-flow and thalweg within a certain distance downstream the piers will deviate to on...
对桥渡附近的河床变形进行了实验研究,认为在桥墩走向与主流方向存在一定偏角时,桥墩附近的水流结构和河床变形将会不同于没有偏角时的情况,如增大阻水宽度,起到导流作用,使局部冲刷坑增大变深,以及能使下游一定范围内主流位置和深槽位置向某一侧发生偏移。

This paper reviewed the developments in 2-D numerical model of the water flow. By means of the latest observation data of the prototype, the detailed analysis was made on the major thalweg, section, island and bottomland, the erosion and deposition of the river bed and the scour hole near the dock and the law of the fluvial process was obtained. Based on the related references, the evolution trend of the channel after the Three Gorges was finished was predicted. The 2-D mathematical model of the water flow was set up and validated using the latest data. With the model, the flow and velocity of several cases were calculated. The stability computation of the bank at the typical section under difference conditions was carried out by adopting the world widely used Geo-Slope slope stability analysis program. Finally, the synthetical evaluation on the influence of the project on the flood level, velocity, river circumstances, bank protection and flood prevention was made and the conclusion that the construction of the dock had little effect on the flood discharge was obtained.
