Organiser: Dr Lynda Yorke
Overall aims and purpose
- To provide a foundation and conceptual framework in which to understand fluvial, coastal and deep marine environments, including intrinsic and extrinsic processes operating within such systems.
- To understand the main hydrodynamic and sedimentary processes operating within and characterising the channel, floodplain, coastal and marine environments.
- To provide an overview of the external (climate change, human activity, tectonics and base-level change) and internal controls on river systems and examine the associated river responses at a range of spatial and temporal scales.
- To present the climatic and oceanographic controls on open coast and deep sea sediments and sedimentary environments.
- To introduce students to the current debates and literature in this field and discuss the relevant application to present-day management of fluvial and marine environments.
This module takes a catchment to marine basin approach, focusing on riverine, coastal and deep marine environments. The module will provide a foundation and conceptual framework in which to understand river and marine systems, environmental change and geochronologies. Response to climate change, human activity, tectonics and base-level change during the Quaternary will be explored, along with developing an understanding of both intrinsic and extrinsic processes operating within these different but connected environments. The module will examine sediments within these environments, which are important components of key dynamic, biogeochemical and ecological systems, and have major socio-economic significance. This module examines the origin, controls, and processes that determine the properties, transport and deposition of sediments in rivers, shallow water environments (e.g. beaches, barriers, deltas, tidal flats), continental shelf and slope environments, and the deep ocean basins. The module will take both an applied and scholarly approach to the subject, introducing the students to the current debates and literature in the field.

Teaching and Learning Strategy
Students will undertake both direct learning and private study so that they engage with the core literature. Students should use some of the time to perpare for workshops, practicals and assessments.
Lecture-based learning to deliver the core concepts and theories in this subject.
2 day field course to the Aberystwyth area to take a source to sink approach, and ancient to comptemporary viewpoint in terms of rivers, coasts and oceans.
