2A MATHEMATICAL MODEL FOR RESERVOIR SEDIMENTATION AND FLUVIAL PROCESSES显示文摘This paper consists of two parts: mechanism of non-equilibrium transport of non-uniform sediment and its application in the mathematical model. Based on a statistic approach of sediment transport proposed by the authors, a 1 - D equation of non-e- quilibrium transport for various size group of sediment particles is developed. Then equations to predict change of sediment concentration and the corresponding changes in size distribution of suspended load and bed material are also derived. The conception that changes in size distribution are interrelated to sediment-carrying capacity is expounded. These results reveal the essence of sediment transport of non-uniform sediment particles. In the second part a mathematical model incorporating the mentioned equations to compute deposition and scouring in reservoirs as well as the fluvial processes of river channels has been developed. Verification of the model agrees well with field data.Han Qiwei and He Mingmin (Senior Research Engineers, Dept. of Sedimentation Eng. Inst. of Water Conservancy and Hydroelectric Power Research.)

3RILL EROSION PROCESS ON STEEP SLOPE LAND OF THE LOESS PLATEAU显示文摘Rill erosion processes and principle of preventing rill erosion of different applied measures are studied by rainfall simulation and field investigation. Research results show that rill erosion processes can be schematically divided into five stages, that is, concentrated flow forming process; little waterfalls in the concentrated flow forming Process; little waterfalls developing into rill head cut process; rill head cuts developing to form discontinuous rill process and discontinuous rills connecting to form continuous rill process. Rill head cuts backward erosion, rill wall collapsing and runoff washing rill bed are the main patterns of rill development. The relevant equation between critical runoff volume of occurring rill erosion and slope degree can be expressed as follows: Q = 76. 10 - 2. 10J. And relevant equation between critical slope length of occurrence Of rill erosion and slope degree is parabolic with a minimum-value. In addition, influence of rill erosion development on slope runoff and soil erosion, benefits and principle of reducing rill erosion amount of mulch, non-tillage system and remained residue, strip alternation of grass and crop, horizontal ditch are also studied.ZHENG Fenli and TANG Keli (1 The English text has been altered and edited by Dr. DING Lianzhen 2 Engineer, National Key Laboratory of Soil Erosion and Dryland Farming on Loess Plateau, Chinese Academy of Sciences and institute of Soil and Water Conservati 1997International Journal of Sediment Research1997,12,1:9

18SEDIMENT TRANSPORT MODEL OF A WATERSHED显示文摘The natural watershed is simply represented by a multi-order river net system, so the sediment transport process in watershed can be considered as sediment transport in the system. Based on this assumption, a new sediment graph model-Inverse Gaussian distribution instantaneous unit graph model is introduced in this paper. Then, the parameter estimation and other specific computational procedure are discussed. With the verification of 27 flood events measured in Chabagou watershed (in hilly and gullied areas of the Loess Plateau, Northern Shaanxi), the results are satisfactory and the model has a distinguishing feature in flexibility, model structure, and parameter numbers (only two). In addition, the phase difference between measured and simulated sediment flux are presented. and satisfactory results are obtained.LI Huaien (1 The English text is edited by Dr. DING Lianzhen. 2 Associate professor, Xian University of Technology, Xian 710048, P.

19EFFECT OF SUSPENDED SEDIMENT ON THE TRANSPORT AND TRANSFORMATION OF 4 - NITROCHLOROBENZENE IN THE YELLOW RIVER显示文摘A simulation study of 4 - nitrochlorobenzene (P- NCB ) in the Yellow River has been per- formed. Parameters include partition on suspended sediment, volatility, and photolysis of pNCB in natural water body. The models consist of water hydrodynamics, DOC deoxygenation, and P-NCB water quality submodels. The results show different effects at different concentrations of suspended sediment and concentration of total organic carbon(TOC).SHEN Xianchen (1 The English text is edited by Dr. DING Lianzhen 2 Senior Engineer, Water Quality Research Centre, China institute of Water Resources and Hydroelectric Power Research, Beijing 100044, P.

20First Steps for New Government显示文摘The formation of a unity government brings hopes of peace and stability to war-torn Iraq, though violence continues Thirty-eight months after the war on Iraq began, and after five months of wrangling over cabinet posts, a new national government led by Nuri al-Maliki was sworn in, marking a great step in the country's post-war reconstruction but one on a road that appears to be growing ever longer and rockier.By DING YING 2006Beijing Review2006,49,23:0
