Description

This course provides an introduction to the concepts and reductionist approach involved in the modelling of catchment processes influencing the quantity and quality of surface runoff from a catchment. Different forms of conceptual models are introduced and how these concepts are combined to provide a catchment modelling system. Considerations, limitations and implementation of catchment modelling systems is discussed, with a focus on calibration, validation and sensitivity testing of a catchment system model. An introduction to the processes influencing the generation and movement of surface runoff and pollutant constituents, and associated routing flows and constituents along the channels and rivers in a catchment drainage network is covered to facilitate an understanding of the possibilities and limitations of catchment modelling. Finally, the information and data required for the use of these modelling systems to provide insights, inclusive of sources of this information are also examined.

2.	Interpret uncertainty within catchment modelling systems and identify key drivers. (D.1)
3.	Apply alternative approaches for parameter estimation. (D.1)
4.	Design different approaches to modelling of water quantity and quality in catchments. (D.1)

Course intended learning outcomes (CILOs)

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

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.
• 2.2. Fluent application of engineering techniques, tools and resources.
• 2.4. Application of systematic approaches to the conduct and management of engineering projects.

Teaching and learning strategies

Teaching and learning strategies will include:

• Workshop content (online content)
• Workshop/tutorial sessions (in-class and online content)

Each teaching period focuses on a particular aspect of catchment modelling. There are reading materials that provide a foundation for aspects of the subject and are made available on Canvas. In each block period, these reading materials form an integral part of the discussion and the formation of technical arguments. Students are encouraged to engage with the online activities prior to the Friday block class to facilitate their interaction in lectures and tutorials where they have opportunities to apply their knowledge.

Each student is expected to contribute to the discussion and to present a viewpoint. As part of these collaborative discussion periods, a peer review of arguments is expected. In addition, these discussion periods provide opportunities for verbal feedback to guide students in the preparation of their technical reports. Detailed feedback will be provided on the written reports. The discussion periods and the technical reports provide opportunities for students to develop their analytical, review, reflection and evaluation skills.
