Rouse number: mode of transport vs. grain size. suspended load sediment transport. A defining trai t of mankind is its thirst for k nowledge and its ability to communicate and record its findings. Originally , those endeavours were directed at the day - to - day needs of survival Objectives. Learn basic concepts of sediment transport and fluvial geomorphology. Understand sediment budgets (sources, sinks, pathways for sediment). Discuss infrastructure and ecosystem response. 1. Motivation. Effect of water on landscape:. Whereas hydrologists are mostly concerned with the movement of water, a common task is to assess the impact of water flow on the transport of materials – sediment and solutes.
