恒河、布拉马普特拉河、梅克纳河（GBM）流域覆盖了印度、尼泊尔、不丹、孟加拉国和中国180万平方公里（图一）。据估计，到2020年，流域内的总人口将达到10亿。整个流域的人口密度差异很大，从孟加拉国的每公里850人(2)到尼泊尔的每公里121人(2)。流域管理的一个重要问题是，在人口密集和快速增长的情况下，如何保持流域的自然资源，以满足人口对食物和水的需求。一个关键的RBM问题是孟加拉湾附近沿海地区的盐入侵。在这项研究中，Savenije（1992,1993）开发的快速评估技术已被整合到流域管理工具Stream中（van Deursen & Kwadijk, 1994; Aerts, 1997； Aerts等人，1998）。该仪器能够对河口盐侵入的长度和浓度进行空间分析。该技术已应用于孟加拉国的珊瑚河口系统，以支持估计盐入侵对淡水供应、鱼类种群和农业生产的影响。(C) 2000, Elsevier Science Ltd.出版版权所有。
The Ganges, Brahmaputra, Meghna (GBM) catchment covers 1.8 million square kilometres of India, Nepal, Bhutan, Bangladesh and China (Figure I). It is estimated that by the year 2020 the total population within the basin reaches 1 billion people. The population density varies widely over basin from 850 per km(2) in Bangladesh to 121 per km(2) the in Nepal. An important question related to river basin management (RBM) is, given the dense- and the fast growing population, how to maintain the natural resources in the basin in order to satisfy the needs for food and water for the population. One of the key RBM issues is salt intrusion at the coastal areas near the Bay of Bengal. Within this study, a rapid assessment technique developed by Savenije (1992, 1993) has been integrated in the river basin management instrument Stream (van Deursen & Kwadijk, 1994; Aerts, 1997; Aerts et al, 1998). The instrument enables the spatial analysis of the length and concentration of salt intrusion in estuaries. The technique has been applied on the Coral estuary system in Bangladesh to support estimation of the impacts of salt intrusion on fresh water availability, fish stocks and agricultural production.
