Bydd egwyddorion cychwynnol yn cynnwys diffiniad o berygl naturiol, trychineb, risg a cholled ac ymagweddau at leihau risg a rheoli trychinebau. Mae¿r prif fathau o berygl naturiol yn cael eu hastudio er mwyn deall sut maent yn gweithredu, ble, a pha mor aml maent yn debygol o ddigwydd. Caiff canlyniadau peryglus eu hystyried, yn ogystal â sut gall y gymdeithas ymateb i ddigwyddiadau peryglus. Mae agweddau allweddol yn cynnwys trafod peryglon cynradd ac eilradd, rhagweld a monitro peryglon, a deall sut y gellir lleihau eu heffeithiau niweidiol. Bydd y peryglon naturiol a fydd yn cael eu hystyried yn y modiwl hwn yn cynnwys ffrwydradau llosgfynyddoedd, daeargrynfeydd, tswnamïau, tanau gwyllt, tirlithriadau, digwyddiadau tywydd eithafol, llifogydd, cwympfeydd eira a Pheryglon Mawr. Bydd y modiwl hefyd yn ystyried y cysyniad o ¿Bobl fel Peryglon¿. Bydd darlithoedd yn ymdrin ag egwyddorion cyffredinol ynghyd ag astudiaethau achos. Bydd dosbarthiadau ymarferol yn atgyfnerthu¿r cysyniadau a drafodir mewn darlithoedd. Bydd agwedd ymarferol y gwaith hwn yn dod i uchafbwynt mewn diwrnod efelychu rheolaeth mewn trychineb. 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. The module will also consider the concept of ¿Humans as 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.

  • GEG252V Geographical Fieldwork skills: Vancouver

    The module is concerned with identifying and defining geographical questions within the Vancouver and southern British Columbia context 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 Vancouver and southern British Columbia. 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 two-week field course, which typically runs in the last week of teaching block 2 into the first week of the Easter vacation.

  • 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.)

  • GEL121 Introducing Planet Earth: an overview of geology

    Geology is the study of the composition and history of planet Earth and the processes that operate within the planet and on its surface. This module provides an overview of geology, with a strong emphasis on practical and fieldwork. By the end of the module you will be able to identify minerals and rocks, and know how to interpret them to understand the behaviour of volcanoes and earthquakes, and the formation of mountain belts. Teaching through lectures is supplemented by regular practical classes and five half-day field classes. Taking this module alongside Year One Geography modules will complete your credit requirements at Year One. The module is recommended if you have an interest in physical geography, although it is accessible to all students. No previous experience of geology is needed.

  • GEL122 Earth science in the field

    Acquiring fieldwork skills and experience is vital training for Earth scientists. This module develops geological fieldwork skills through two intensive residential weekends, three half-day field classes and an independent field-based project. The first weekend (15-17 November 2019), introduces key aspects of geology in the field, including a variety of rock types, folds and faults, fossils and field relations, as well as developing skills such as keeping a field notebook, making a field sketch, using a compass-clinometer to measure the orientation of rock surfaces, and manipulating structural data. The second weekend (21-23 February 2020) applies knowledge, understanding and experience gained through the year (including in GEL121) to more advanced aspects of geology in the field, including sediment logging, correlation and lateral variation, and basic field mapping. The field weekends are supported by tutorial meetings and assessed through activities undertaken in the field, including a field notebook, and reports prepared afterwards. Local, half-day field classes in Teaching Block 2 focus on geological resource exploitation in the South Wales Coalfield and are assessed through a report. Finally, students undertake an independent project based on the geology of an area of their choosing, producing a poster and a field guide. This module builds on material covered in GEL121 (Introducing planet Earth: an overview of geology) which is a co-requisite, and provides a firm foundation for the study of Year 2 geology modules. The module is compulsory for students enrolled on BSc Physical Earth Science. It is not available to students enrolled for other Geography degree schemes.

  • GEL204 Geological Record of Past Environments

    The geological record gives a long-term perspective on environmental and climatic change, including changes that occurred over hundreds of thousands to millions of years. This record, derived from the interpretation of rocks, provides a long-term perspective on the magnitude and extent of environmental changes and their causes. This module focuses on the reconstruction of environmental parameters from the geological record. Principles and techniques for palaeoenvironmental reconstruction are outlined, with an emphasis on facies analysis and palaeoecology. Sedimentary structures are interpreted in terms of processes of sediment transport, deposition and disturbance. The facies characteristics of major depositional systems are outlined, including deserts, rivers, deltas, the deep sea and volcaniclastic environments. Lectures are supported by a 3-day field course to south Pembrokeshire, where palaeoenvironmental conditions will be reconstructed from well-exposed rock successions. This module builds on aspects of geology introduced at Year One and provides a long-term perspective on environmental and climatic conditions that complements Earth history and physical geography modules. The module is compulsory for students taking BSc Physical Earth Science.
