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. ***

小行星9322601 产品描述：该项目支持两名美国科学家计划访问孟加拉国，以完善一项合作研究计划，涉及来自欧洲，孟加拉国和美国的科学家。 目的是研究恒河-布拉马普特拉河-梅克纳河形成的三角洲平原在现代（100年）时间尺度上和冰期（全新世）以来的沉积和沉降。 这片广阔的河漫滩可能是这个世界上最大的河流系统排放的40-80%的沉积物的汇。 了解该系统的总体沉积物预算具有地方和全球相关性。 在孟加拉国，每年有35-40%的地区被洪水淹没，量化和绘制沉积和沉降模式是实施防洪工程的先决条件。 适用范围：需要广泛的科学和后勤规划，将这项研究与现有的孟加拉国-欧洲联合研究河流水动力学和形态。 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通过对可能的取样地点的实地检查来进行协调。 ***
