fluvial geomorphology

Fluvial geomorphology is the study of how rivers shape the landscape as they remove water and sediment supplied to them from the land surface and carry it to lakes and oceans. On a global scale, rivers and their floodplains are one of the most exploited of all natural environments. In SE England there are increasing pressures on floodplains and water supplies because of a rising population and the requirement for house building programmes. Fluvial geomorphologists are key to developing our understanding of the aquatic environment and managing these pressures. And as part of multi-disciplinary teams, working with river engineers and hydroecologists, can address a range of key requirements in water and catchment management, including:

• risk and environmental impact assessment
• floodplain planning and sustainable flood risk management
• determination of in-stream flow needs and physical habitat requirements
• river restoration to meet targets for good ecological status
• design of ecologically-acceptable channels and structures

HYDRA scientists have particular expertise in studying the dynamics of rivers where in–channel plants have a significant effect on flow velocities, water levels, and sediment transport and deposition. Understanding the effects of vegetation on flows is important for managing flood risks and a knowledge of fine sediment dynamics is fundamental to predictions of sediment-associated contaminant transfer in rivers.
