  • GEC266 Ymdrin â Daearyddiaeth Ffisegol

    Bwriad y modiwl hon yw i gyflwyno myfyrwyr i hanes ac athroniaeth daearyddiaeth ffisegol, a'r wahanol ffyrdd o ymdrin a'r ddisgyblaeth. Yn ogystal a chyfleu syniad o'r prif ymatebion hyn a'u hysblygiad, roddwyd pwyslais hefyd ar eu pwysigrwydd yn nhermau ymarferion ymchwil, gan dynnu sylw yn arbennig i esiamplau cyfoes o wyddoniaeth 'da' a 'drwg'. Bydd myfyrwyr yn archwilio datblygiad y wahanol ffurdd o ymdrin a daearyddiaeth ffisegol a beth yw goblygiadau hyn i ymchwil trwy astudio testunau allweddol yn hanes y disgyblaeth. Mae'r cysylltiad rhwng yr ymatebion ymchwil damcaniaethol ac ymarferol a fydd hefyd yn cael ei amlygu drwy creu: portffolio grp;adolygiad llenyddiaeth unigol.Yn ogystal, mae 5 darlithoedd ar gyflogadwyedd. This module aims to introduce students to the history and philosophical approaches of Physical Geography and the range of alternative approaches characterizing the discipline. In addition to conveying the main approaches and their evolution, their implication in terms of research practice are given particular emphasis, including recent examples of `good¿ and `poor¿ science. The way in which alternative approaches to Physical Geography have developed and what this entails for research is explored partly through student-centred investigation of key topics in the history of the discipline. The link between conceptual approaches and research practice is also highlighted in the development of a `mock¿ and a `real¿ research proposal, the latter covering the topic to be pursued as the future dissertation project. The module also includes 5 careers lectures which explore the career opportunities for Geography graduates and ways of further enhancing your employability.

  • GEG111 Geographical Writing Skills and Personal Development Planning

    This module introduces students to key skills in scientific writing and career development. The module is taught through a tutorial programme throughout the year.

  • GEG133 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. Hazardous consequences are explored, as well as how society can respond to hazardous events. Key aspects include discussion of primary and secondary hazards, prediction, forecasting and monitoring of hazards, and understanding how their harmful effects can be minimised. Natural hazards considered during this module include volcanic eruptions, earthquakes, tsunamis, wildfires, landslides, extreme weather events, flooding, avalanches and Mega Hazards. Lectures consider general principles as well as case studies. Practical classes reinforce concepts learned in lectures. The practical aspect of the work will culminate in a disaster management simulation day.

  • 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.

  • GEG266 Approaches to Physical Geography

    This module aims to introduce students to the history and philosophical approaches of Physical Geography and the range of alternative approaches characterizing the discipline. In addition to conveying the main approaches and their evolution, their implication in terms of research practice are given particular emphasis, including recent examples of `good¿ and `poor¿ science and of how research proposals are developed. The assessment will include a literature review and a multiple choice exam.

  • 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.

  • GEG333 Geographical Research Frontiers

    This module provides students with the opportunity to demonstrate their competence as a Geographer by undertaking a critical analysis of a wide variety of literature-based sources in order to develop a cogent, substantial, and persuasive argument. While the Dissertation in Geography normally focuses on the design and execution of an evidenced-based research project that assesses the capacity of students to undertake effective data analysis and interpretation, the purpose of this module is to assess the extent to which students are capable of engaging with the academic literature at the frontier of a particular part of Geography. Students select from a wide range of research frontiers in Human and Physical Geography that have been identified by the academic staff within the Department. Given that this module emphasizes student-centred learning, none of the frontiers will have been covered in other modules, although in many cases modules will have taken students up to some of these frontiers. However, to orientate students and provide them with suitable points of departure and way-stations, there will be a brief introduction to each frontier and a short list of pivotal references disseminated via Blackboard. (Note: The topic selected by you must not overlap with the subject of your Dissertation. If there is any doubt about potential overlap, this must be discussed with your Dissertation Support Group supervisor and agreed in writing.)

  • 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.
