20 Credits or 10 ECTS Credits

Semester 2

Organiser: Dr Lynda Yorke

Overall aims and purpose

  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.

Course content

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.

Major themes covered

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

Fluvial Environments: Single (meandering) and multi-thread (braided, wandering) channels Alluvial channels, bars and floodplains Facies, sedimentary sequences, and subenvironments Importance of rivers to marine environment Cable Bay as natural laboratory Pilcomayo case study & Ebro/Rhone/Var case study

Alluvial Histories: River response to environmental change Quaternary fluvial history

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

  2. Understand the long-term dynamics of river systems and the controls operating within fluvial systems, and be able to comprehensively discuss how these condition river response to environmental change.

  3. Understand how an interdisciplinary approach is needed to understand the nature of sediment deposits (ES 3.2.1.1)

  4. Synthesise and summarise interdisciplinary information critically (ES 3.3.4.2), and critically analyse the literature.

  5. Reconstruct ancient sediment environments using data gathered through field observation

  6. Demonstrate knowledge of the key concepts governing fluvial behaviour in a catchment. Understand the concepts and principles which govern marine sedimentary environments (ES 3.3.4.1)

  7. Understand physical and key biological controls of sedimentation in coastal and shelf seas, and deep sea environments, and the temporal and spatial scales of variation, and anthropogenic impacts (ES 3.2.1.2)
