Description

This subject aims to teach students the main elements of floodplain risk management (FRM) as practised in New South Wales. The FRM process in NSW provides for informed decision-making in the strategic management of flood risk through an appropriate:

  • understanding of flood behaviour in the catchment in its current condition and in considering the long term development of the catchment
  • understanding of the variation in hazard across the floodplain and its different sources and the associated consequences for existing and future development
  • assessment of options to manage flood risk to existing development through mitigation measures from a broad perspective consistent with the NSW Flood Prone Land Policy
  • assessment of options to develop the floodplain in consideration of flood hazard and behaviour to ensure that development extents and conditions are consistent with the maintenance of flood behaviour, the residual flood hazard and the objectives of the policy.

The subject is aimed at a wide body of students seeking a detailed knowledge and background in FRM and associated land use planning issues in NSW. The subject is supported by the NSW Department of Environment and Climate Change and the Floodplain Management Authorities of NSW.

Subject learning objectives (SLOs)

Upon successful completion of this subject students should be able to:

1. Explain flood behaviour in the catchment in its current condition and able to relate this to the long term development of the catchment. (D.1)
2. Distinguish the variation in hazard across the floodplain and its different sources and the associated consequences for existing and future development. (D.1)
3. Critically assess options to manage flood risk to existing development through mitigation measures from a broad perspective consistent with the NSW Flood Prone Land Policy. (C.1)
4. Critically assess options to develop the floodplain in consideration of flood hazard and behaviour to ensure that development extents and conditions are consistent with the maintenance of flood behaviour, the residual flood hazard and the objectives of the Policy. (C.1)

Course intended learning outcomes (CILOs)

This subject also contributes specifically to the development of the following Course Intended Learning Outcomes (CILOs):

  • Design Oriented: FEIT graduates apply problem solving, design thinking and decision-making methodologies in new contexts or to novel problems, to explore, test, analyse and synthesise complex ideas, theories or concepts. (C.1)
  • Technically Proficient: FEIT graduates apply theoretical, conceptual, software and physical tools and advanced discipline knowledge to research, evaluate and predict future performance of systems characterised by complexity. (D.1)

Contribution to the development of graduate attributes

Engineers Australia Stage 1 Competencies

This subject contributes to the development of the following Engineers Australia Stage 1 Competencies:

  • 1.3. In-depth understanding of specialist bodies of knowledge within the engineering discipline.
  • 1.5. Knowledge of engineering design practice and contextual factors impacting the engineering discipline.
  • 2.2. Fluent application of engineering techniques, tools and resources.
  • 2.3. Application of systematic engineering synthesis and design processes.
  • 3.1. Ethical conduct and professional accountability.
  • 3.5. Orderly management of self, and professional conduct.
  • 3.6. Effective team membership and team leadership.

Teaching and learning strategies

All block class sessions for this subject will now be conducted online. There will be no face-to-face or on-campus class and consultation sessions for this subject. The subject coordinator and teaching staff in the subject will facilitate these block class sessions via Zoom and/or MS teams at the scheduled times of teaching activities to answer student queries.

In preparation for block classes students should watch the introductory video on Canvas. Students should reflect on the issues raised in the video and the questions posted on Canvas related to the video. This will be discussed during a tutorial during block 1 where students can share reflections and feedback with colleagues in tutorial groups. The discussion is moderated by the subject coordinator, affording the opportunity to provide feedback on students reflections and answers and direct further learning.

In this subject there are numerous formative assessments activities (some do not contribute to overall assessment) from Block 1 onward that are designed to allow students to practice using their new knowledge/skills and receive feedback from the lecturer.

The lectures are interactive in all aspects of the course of instruction, which will include the use of power-point presentations and selected videos. Students are expected to actively take part in class discussion to, in part, help build their communication skills as well as consolidate concepts of stormwater design. The lectures will have a practical bias.

Students are expected to read the indicated materials and answer the associated online questions before the lecture so that the lecture can focus on problem solving activities individually or in small groups and any problematic material rather than parts which students can understand by themselves.

All relevant lecture material including notes, videos, reference material, design handbooks, tutorials, online questions, assignments, etc will be placed on Canvas. Teaching materials have a practical focus that aims to be relevant to professional engineering practice. Some of the workshops and tutorials may be given by guest lecturers with industry expertise to link the subject to professional engineering practice.

Content (topics)

Introduction to Floodplain Risk Management

The objectives are:

  • a good understanding of how FRM is undertaken in NSW and the roles of relevant agencies;
  • a good understanding of the principle of FRM and the desired outcomes of FRM projects;
  • improved skills to work on FRM projects and be more effectively involved in the FRM process; and
  • improved ability to specify and manage FRM projects.

The syllabus include:

  • The FRM Partnership – identifying roles and responsibilities;
  • Working within the FRM Process – understanding technical terms, discussing the management of the process from establishing committees, grant applications and management, brief development and project management, through to working with committees to develop and implement FRM plans;
  • Data Collection. Understanding the data that is necessary and the sources and costs;
  • Modelling Basics and Model Review. Overview of model purpose, operation, selection and limitation. Along with an outline of the key issues to consider in the specification and review of modelling;
  • Understanding the need for and the basics of defining flood and hydraulic categories;
  • Overview of the desired outcomes from the FRM Process and how these can be assessed; and
  • Roles during and after a major flood.
