| 1 | LABORATORY EXPERIMENTS ON NAVIGATION-INDUCED BED SHEAR STRESSESAND SEDIMENT RESUSPENSION显示文摘Motivated by the need to assess the environmental impact of navigation in the upper Mississippi River basin. a method was developed for computing sediment.entrainment in unsteady flows similar to the flows induced by navigation traffic. The method accounts for statistical differences between bed shear stress distributions of steady and unsteady flows. Unsteady pulse flow tests performed in a laboratory flume indicate that the stochastic method works well for predicting entrainment, but not significantly better than a similar deterministic method. Temporal and spatial distributions of bed shear stress were also measured beneath a 1:25 scale model of a 3 barge wide by 5 barge long barge tow for a variety of flow and operating conditions. For one set of flow and operating conditions (PDF test) a large number of realizations were gathered so that statistical properties of the bed shear stress below the propeller axis could be observed. As in the laboratory tests, differences between stochastic and deterministic entrainment predictions were small for the PDF barge tow test. Consequently, deterministic calculations of total sediment entrainment are given for the remaining barge tow tests. Finally. it was found that although the stochastic model presented herein does not offer a large improvement over existing deterministic models, fluctuations in bed shear stress do play an important role in the suspension of sediment, and the timing of sediment entrainment in unsteady flows is more closely related to shear stress fluctuations than it is to the ensemble averaged shear stress. | M.H GARCIA D.M.

| 10 | Testing for additivity with B-splines显示文摘Regression splines are often used for fitting nonparametric functions, and they work especially well for additivity models. In this paper, we consider two simple tests of additivity: an adaptation of Tukey’s one degree of freedom test and a nonparametric version of Rao’s score test. While the Tukey-type test can detect most forms of the local non-additivity at the parametric rate of O(n-1/2), the score test is consistent for all alternative at a nonparametric rate. The asymptotic distribution of these test statistics is derived under both the null and local alternative hypotheses. A simulation study is conducted to compare their finite-sample performances with some existing kernel-based tests. The score test is found to have a good overall performance. | Heng-jian CUI, Xu-ming HE & Li LIU Department of Statistics and Financial Mathematics, School of Mathematical Sciences, Beijing Normal University, Beijing 100875, China Department of Statistics, University of Illinois, Champaign, IL 61820, USA National Institute of Statistical Science, Durham, NC 27709, USA | 2007 | Science China Mathematics2007，50，6： | 1 |
| 11 | FINE SEDIMENT OF THE UPPER MISSISSIPPI ANDILLINOIS RIVERS AND THE DISASTROUS CONSEQUENCES显示文摘Increased sediment loads and sedimentation rates in rivers and streams have produced major disturbances to the society. However, while discussing f sediment transport and sediment induced problems focuses have often been given to those related to coarse sediments; tine sediment induces problems have been primarily investigated in bays and estuaries. In the case of Upper Mississippi River System (UMRS), increased turbidity and suspended sediment solids in the water column; heavy sediment deposition in channel boarders, backwater lakes, and side channels have shown to be problematic. Besides their impacts on human activities, fine sediments have also adversely affected water quality and flora and fauna of the river System. The total areas that affected, their accessibility, the amount, not to mention the contaminants involved, are complex challenges to the e1Yorts to restore the rivers’ functions. Many resource managers consider heavy sediment deposition in backwaters and side channels to be one of the most severe environmental problems on the UMRS. Large rivers are priceless resources and sedimentation plays a vital role in their sustainability. The example and experience learned from the UMRS can provide valuable information for management practices of other river basins. | TaWei SOONG1 (l Watershed Science Section, Illinois State Water Survey.

| 13 | EROSION AND SEDIMENT MANAGEMENT STRATEGIESFOR THE ILLINOIS RIVER显示文摘The Illinois River is the single most important river in the state of Illinois. Approximately 95 percent of the urban areas and half of the agricultural lands in the state are located within the Illinois River basin. The Illinois Waterway, which consists of the Illinois River and its tributary streams. is the only waterway that links the Great Lakes to the Mississippi River and thus the Gulf of Mexico. The Illinois Waterway is therefore an important commercial waterway. Because of its strategic location in the state and because it is downstream of the Chicago Metropolitan Area, the Illinois River has experienced significant human influences over the years. The most significant influences have been related to commercial navigation, municipal and industrial waste discharges, and agricultural practices in the watershed. Because of the lack of a basinwide comprehensive management plan. many of the environmental and ecological problems in the Illinois River basin have not been addressed adequately over the years. The most serious and difficult to manage problem facing the Illinois River is the problem of sedimentation in the river channel and backwater lakes. Many of the backwater lakes have lost over 70 percent of their capacities to sediment accumulation and might not last too long unless appropriate rehabilitation and management techniques are applied in the near future. Problems in the Illinois River basin are not, however, limited only to sedimentation. Issues such as water quality, nonpoint source pollution, flooding, degradation of aquatic habitats, and water based recreation need to be addressed. It is therefore important that a comprehensive management plan that treats the river, its valley, and watershed as an integrated system and that deals with all the environmental problems, is developed for the Illinois River basin. | Misganaw DEMISSIE (Illinois State Water Survey. 2204 Griffith Drive, Champaign, IL 61820, USA) | 1999 | International Journal of Sediment Research1999，14，2： | 0 |
