  • GEG102 Earth's Changing Face

    Every geographer should have an understanding of the processes that form the landscape, the ways such processes have operated in the past and how they may change in the future in response to human activities and climatic change. Emphasis is given in the module to processes and how they vary across the Earth¿s surface, factors that affect Earth surface systems in different environments, and the likely consequences of human interference with natural processes. There are two main themes: 1) geomorphological and hydrological processes and their interaction with climatic change and society; and 2) natural environmental change on long and shorter timescales.

  • GEG206 Dangerous Earth: Understanding and Living with Natural Hazards

    This module investigates hazardous aspects of Earth¿s natural environment and how society relates to them. Introductory principles include the definition of natural hazard, disaster, risk and loss, and approaches to reducing risk and managing disasters. Major types of natural hazard are studied in order to understand how they operate, where, and how frequently they are likely to occur. Their hazardous consequences are explored, as well as how society can respond to hazardous events. Key aspects include consideration of the factors that turn natural hazards into disasters, how the hazardous nature of natural environmental agents can be predicted, forecast and monitored, and how their harmful effects can be minimised. The major natural hazards considered are volcanoes, earthquakes, tsunamis, wildfires, slope failures and high-magnitude-low-frequency events such as meteorite impacts. Lectures consider general principles as well as case studies. A project (50% of module assessment) comprises submission of an individual poster dealing with a specific event, and presentation of a short seminar as part of a group.

  • GEG252M Geographical Fieldwork skills: Mallorca

    The module is concerned with identifying and defining geographical questions within the Mallorca, which serves as an example of a region with a Mediterranean climate, and applying relevant geographical skills, knowledge and techniques to these questions. The general aims are to observe, analyse and achieve an understanding of the varied geographical landscape and inherent features of Mallorca and the Mediterranean. Students taking this module will gain experience in research design, methodologies, data analysis and presentation methods, including seminars, posters and reports. Students taking this field course focus on either the physical or human geography on the region and conduct project work appropriate to their specialism. The module comprises preparatory lectures in Swansea during teaching block 2 and a one week field course, which typically runs in the last week of teaching block 2.

  • GEG264A Environmental Research Methods A

    The module covers research project design, data collection and some aspects of data analysis. Students are introduced to a range of laboratory and field techniques in physical geography. They gain experience in describing and interpreting results derived from laboratory techniques concerned with reconstructing the depositional history of sediments, chemical analysis of water and sediment from a variety of sources and the simulation of geomorphological processes.

  • GEG331 Dissertation Report: Geography

    The dissertation is an original, substantive and independent research project in an aspect of Geography. It is typically based on approximately 20 - 25 days of primary research and several weeks of analysis and write-up. The end result must be less than 10,000 words of text. The dissertation offers you the chance to follow your personal interests and to demonstrate your capabilities as a Geographer. During the course of your dissertation you will be supported by a student-led discussion group and a staff supervisor, and you will also provide constructive criticism to fellow students undertaking related research projects, learning from their research problems and subsequent solutions. This support and supervision is delivered through the 'Dissertation Support' module, which is a co-requisite.

  • GEG332 Dissertation Support: Geography

    This module provides structured, student-led peer-group support and academic staff group supervision for students undertaking the 30-credit 'Dissertation Report: Geography' module. This support and supervision is assessed through the submission of a PowerPoint Poster in TB1 and the submission in TB2 of an individually composed, critical and reflective log of the 5 dissertation peer-group meetings and the 4 group supervisory meetings (with a verified record of attendance at meetings). Working within a supervised Student Peer Group, you will also have the opportunity to provide constructive criticism to fellow students undertaking related research projects, learning from their research problems and subsequent solutions. This module complements the 'Dissertation Report: Geography' module, which is a co-requisite.

  • GEG345 Humid Tropical Environments and Landscapes

    The module examines the range and nature of humid tropical environments and landscapes and how they respond to climatic factors and climatic change. Section I focuses on the climatic environment. Section II investigates hydrological and geomorphological processes within the humid tropical zone and the impacts of logging. Section III is devoted to climatic change and its forcing factors and their interactions with vegetation in the humid tropics at a variety of timescales. Section IV considers landforms and landscapes in the humid tropics, with Individual lectures focusing upon landscape form and drainage networks; tropical karst and coral reef islands.

  • GEGM07 Principles of Environmental Dynamics

    This module aims to explain and understand past, present and potential future changes in the Earth's climate and environment. It provides a broad approach to environmental processes and dynamics operating on land, in the oceans and in the atmosphere on a global and regional scale. Emphasis is placed on the evidence available for reconstructing past environmental dynamics, the implications for present-day processes, future predictions and likely impacts.
