| 1 | Assessment of the role of slit as a safety valve in failure of levees显示文摘The development of a narrow channel or slit due to piping just underneath the base of levees channel has been reported to be useful to withstand the increase in the head beyond critical head conditions. Also, the maximum slit length has been emphasized to be up to half of the base width. By developing a model of critical head considering slit, it is found that the critical head can increase with the development of slit length only under certain conditions. Analysis of piping failure data indicates that the critical head expressions considering slit length constitute a potentially useful model for critical head. | C.S.P.OJHA V.P.SINGH D.D.ADRIAN | 2008 | International Journal of Sediment Research2008，23，4： | 4 |
| 2 | Braiding process and bank erosion in the Brahmaputra River显示文摘现在的工作探索在溪流力量之间的关系,编织在 Brahmaputra 河的某些段的紧张和河岸侵蚀。在这份报纸,一条客观途径被介绍启用对由使用计划形式索引和溪流力量的相应评价建立编织 Brahmaputra 河的过程的隧道的时间空间的行为的量的评价一行为势能开销的可变性的模式。编织索引被比较分离的年理解词法行为。随后,为 Brahmaputra 河的某些段的溪流力量的一个实时评价被做以便在编织紧张和河岸侵蚀分析它的可变性。纸在 18 年的时间跨度上在印度的阿萨姆山谷论述 Brahmaputra 河系统的隧道模式的动态行为。过程从数字卫星图象探讨输入参数的选择,包括为年的场面 1990, 1997 和 2007 与特定的日期一起,从到上面的阿萨姆的 Indo 孟加拉国边阶附近的 Dhubri。GIS 技术的推广被做了提取要求的参数为全部学习活动范围导出计划形式索引。溪流力量评价为相应最近的洪水并且为图象场面的相应日期被做。学习显示由于导致溪流力量的时间的偏斜的河床的一致沉积,有宽传播编织的出现。这接着由于河岸侵蚀招致实质的每年的陆地损失,在 Brahmaputra 河里由于多重隧道的时间的进化由流动集中引起了。 | M.P.AKHTAR NAYAN SHARMA C.S.P.OJHA | 2011 | International Journal of Sediment Research2011，26，4： | 1 |
| 3 | Variation of turbidity during subsurface abstraction of river water: A case study显示文摘Rivers are known to carry sediment loads. Many rivers in Asia including Kosi, Brahmaputra, Bagmati rivers in India and Yellow and Yarlung Tsangpo rivers in China are well known for their carriage of excessive sediment loads. In India, many water abstraction units are located along river banks. Their success depends on how the sediment load is trapped as the sediment laden water flows towards the pumping wells located few hundred meters away from river bank. In this work, based on the analysis of a data of one year on suspended load variations in a canal, located at Haridwar, India, trap efficiency variations are studied during the passage of source water to the abstraction well. Considering the subsurface basin, located within the source water and the abstraction well, as a hypothetical settling basin, variation of trap efficiency is related with the influent concentration. It is observed that the trap efficiency depends on the influent concentration. Appropriate functional forms for the variation of trap efficiency with the influent concentrations are also identified. | A.K.THAKUR C.S.P.OJHA | 2010 | International Journal of Sediment Research2010，25，4： | 0 |
