The shoal protection works in the middle and lower Yangtze River is divided three types, i.e. riprap in bulk, dam body and soft mattress. As a new kind of shoal protection works, because the application time is very short, therefore the beach protection effect and the improvement measure have not thorough researched. In order to better apply to channel regulation project, the simulation technique of the X-type flexible mattress is thorough researched, the aspects of geometry similarity, gravity similarity, plan layout similarity and river bed deformation similarity are solved, the physical simulation technology problem is realized.

First Time

A retrospective analysis of river bed deformation over a 34-year period has been carried out for the first time for the Ural River in West Kazakhstan, in different environmental conditions. Horizontal shifts of the Ural riverbed have been defined according to space shots made in 2012. Erosion risk, as a result of horizontal displacement of the river bed has been determined in West Kazakhstan. A geomorphologic description of the Ural River bed and floodplain, and the dynamics of channel processes in the river within West Kazakhstan are given. The probable pattern of channel realignments for the Ural River has been determined. The paper describes the results of map compilation and related data consolidation with respect to the horizontal river bed shifts in West Kazakhstan, and includes a review of characteristics of the hydrologic and hydrochemical regimes of the river. The main river bed types, which are typical of flat terrain, are also discussed. West Kazakhstan is a region where there is medium-level ecologic stress on the river beds and floodplains.

Six hundred miles west of Hang-chou the Yangtze River emerges from a mountain corridor onto the lowland plain of south-central China. Here the river bed widens sharply and loses depth; the Yangtze winds a snake-like path across a thousand miles of rich, flat, water-laced country, northeastward to Han-yang, then south toward the Po-yang Lake, north again to Chiang-ning (modern Nanking), and finally into the East China Sea at modern Shanghai. Medieval Chinese called it simply “River”—a River among rivers, the designation of an entire S-shaped area whose character depended more on water than on land, the dominant feature of the southern landscape. In the twelfth century this river region developed a strategic importance as it became first the refuge for a besieged court, then an area of contention with barbarian invaders, and finally the principal artery of Chinese control. This transformation reflected a major reorientation of the Chinese mind.

Self-physical simulation technique has been increasingly extensive used in measuring and evaluating the performance of weapon systems. Based on the characteristics of self-physical simulation, measuring methods of this technique to radar range and coordinates tracking accuracy of radar targets have been discussed in this paper, and which lays certain foundations for performance evaluation of weapon system.
