The project will seek to understand the sediment distribution through space and time in the Indus basin and continental margin. Existing sediment provenance data around the Indus delta, continental shelf and fan cannot be explained by a simple "conveyor belt" transport system from mountains to deep-sea. The proponents frame the existing data in clear hypotheses of sediment flux to be tested with the help of additional samples and by linking an understanding of the sediment provenance study to the sediment dynamics of the drainage system. The link to recent human activity on the fluvial drainage will also be considered. The PIs plan to apply modern isotopic fingerprinting and dating techniques to study the history of flux and provenance of sediments. Cooperation with the local institutions in planned.

该项目将寻求通过印度河盆地和大陆边缘的空间和时间来理解沉积物分布。印度三角洲，大陆架和风扇周围的现有沉积物出处数据无法通过从山到深海的简单“传送带”运输系统来解释。支持者将现有数据构建为清晰的沉积物通量假设，并在其他样本的帮助下进行测试，并通过将对沉积物出处研究的理解与排水系统的沉积物动力学联系起来。还将考虑与最近在河流排水的人类活动的联系。 PIS计划应用现代同位素指纹和约会技术来研究沉积物的通量和出处的历史。与当地机构合作。
