Semester 2

Trefnydd: Dr Lynda Yorke

Amcanion cyffredinol

  1. 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.
  2. To understand the main hydrodynamic and sedimentary processes operating within and characterising the channel, floodplain, coastal and marine environments.
  3. 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.
  4. To present the climatic and oceanographic controls on open coast and deep sea sediments and sedimentary environments.
  5. 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.

Cynnwys cwrs

This module deals with the cascade from source to sink, divided up in to three segments: catchment-fluvial, coastal (continental shelf), and deep marine (Sømme et al., 2009). Each segment is a morphodynamic zone, but these zones are also genetically related and dynamically connected (Allen, 2017). Geomorphology, sedimentology, and stratigraphy are core to understanding the flow of sediments within and through these segments. Sediments from single or multiple sources are routed through the source to sink cascade, with each morphodynamical zone connecting regions of erosion, sediment transfer, temporary storage, and long-term deposition.

The module will explore the key foundational and conceptual frameworks (thresholds, sensitivity, drivers) in these geomorphological zones. The module will explore the mechanisms and responses to external factors, such as environmental change, tectonics, base-level change, and anthropogenic activity, alongside developing an understanding of intrinsic and extrinsic processes in these key zones. The module will examine sediments within these zones, which are important components of biogeochemical and ecological systems, and have major socio-economic significance. This module will examine the sediment routing system (origin, controls, and processes that determine the properties, transport, and deposition) in the catchment-fluvial, coastal (e.g., beaches, barriers, deltas, tidal flats) and continental shelf, the deep ocean basins segments. Students will be encouraged to critically engage with the literature and key debates, and to develop a scholarly and applied approach to the subject.

Major themes covered

Foundation and Framework: Equilibrium, thresholds, transition, complexity, and response. External/Intrinsic Drivers (Base level change, Climate, Tectonics, Humans).

Catchment-Fluvial Environments: Geomorphology Single (meandering) and multi-thread (braided, wandering) channels Alluvial channels, bars and floodplains Facies, sedimentary sequences, and subenvironments Importance of river to marine cascade Cable Bay as natural laboratory Pilcomayo case study & Ebro/Rhone/Var case study Alluvial Histories River response to environmental change Quaternary fluvial history

Coastal-Beach Environments: The coastal morphodynamic system Coastal classification: transgressive/progressive; wave/tide dominated Coastal barrier systems and the shoreface Beaches: classification, wave-driven currents, morphology, engineering applications Tidal flats

Deltaic Environments: Classification: wave/fluvial dominance Stratigraphy Continental shelf : Classification: tide/wave/storm dominated Morphological features Sediment budgets

Shelf edge and Deep Marine Environments: Processes, facies, sedimentary sequences, and subenvironments Density cascading Sediment gravity flows Submarine fans and channels and hydrocarbons Contourite drifts Pelagic and hemipelagic sedimentation
