A Planning Visit for Collaborative Research on Sedimentation and Subsidence in the Ganges-Brahmaputra River Delta Plain

9322601米德描述：该项目支持两名美国科学家对孟加拉国的计划访问，以完善一个合作研究计划，来自欧洲、孟加拉国和美国的科学家参与其中。目的是研究恒河-雅鲁藏布江-梅格纳河三角洲平原在现代(100年)和冰期(全新世)以来的沉积和沉降。这片广阔的泛滥平原可能是这个世界上最大的河流系统排放的40%-80%的泥沙的汇。了解该系统的总体泥沙预算对当地和全球都有意义。量化和绘制沉积和下沉模式是在孟加拉国实施防洪工程的先决条件，孟加拉国每年有35%-40%的地区被洪水淹没。范围：需要广泛的科学和后勤规划，以将这项研究与孟加拉国-欧洲现有的河流水动力学和地貌联合研究相结合。这次访问将通过与孟加拉国科学家和政府官员的会议以及对潜在采样点的实地检查来进行协调。***

9322601 Mead Description: This project supports a planning visit by two U.S. scientists to Bangladesh to refine a collaborative research program, involving scientists from Europe, Bangladesh and the United States. The objective is to study the sedimentation and subsidence in the delta plain formed by the Ganges-Brahmaputra- Meghna rivers on modern (100 years) time scale, and since the glaciation (Holocene). This vast floodplain may be the sink for 40-80% of the sediment discharged from this river system, which is the world's largest. An understanding of the overall sediment budget for this system has local as well as global relevance. Quantifying and mapping sedimentation and subsidence patterns is a prerequisite to implementing flood control engineering in Bangladesh where 35-40% of the country is flooded annually. Scope: Extensive scientific and logistic planning is required to integrate this study with an existing joint Bangladesh-European study of river hydrodynamics and morphology. The visit will allow that coordination through meetings with Bangladesh scientists and government officials, and through field examination of potential sampling sites. ***
