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.

该项目将设法了解印度河流域和大陆边缘沉积物的时空分布情况。印度河三角洲、大陆架和扇周围现有的沉积物来源数据不能用简单的从山区到深海的“传送带”运输系统来解释。支持者以明确的沉积物通量假设为现有数据的框架，这些假设将借助更多的样本进行检验，并将对沉积物来源研究的理解与排水系统的沉积物动力学联系起来。还将考虑与最近人类活动对河流流域的影响。研究所计划应用现代同位素指纹和年代测定技术来研究沉积物的通量和来源的历史。计划与当地机构合作。
