Management science techniques in water resources. Water resource systems, dams and reservoirs, river engineering, restoration and modelling.

Water is an essential component to all forms of life. In this course we will look at surface and ground water, the supply and demand side, especially in connection to allocation of water resources, engineering solutions in relationship to extreme flows (both high and low) and restoration. Irrigation engineering takes a special place in the field of water resources engineering as it has the potential to bring economic welfare and food security, but also has the potential to be harmful and destructive. Sound knowledge of the underlying principles and fundamentals is required to ensure that both water resources engineering and irrigation engineering are practised in a sustainable manner. This course aims to provide that knowledge and teaches students to understand and criticise risks and benefits in these fields.

Learning Outcomes

This course builds on the knowledge students gained from previous courses, most notably ENCN242 Fluid Mechanics and hydrology, ENCN342 Fluid Mechanics & Hydraulics and ENNR320 Integrated Catchment Analysis. The course will advance students' specialised knowledge of water resources engineering and introduce them to the fundamentals and principles of irrigation engineering. Students will be provided with the theoretical and practical knowledge that allows a critical understanding of the fields of water resources and irrigation engineering. Assessment is through problem solving and examinations at the end of each term.

Students develop their skill through applying their knowledge to complex and often unpredictable problems related to the field of water resources and irrigation engineering. These skills are assessed mainly through a group project which has students analysing and criticising existing water resources engineering projects and allows them to develop their own alternative solutions.

Students are required to apply their knowledge and skills learned in this course to a design project. The design allows advanced generic skills and knowledge to be applied into a professional context, in this case a real irrigation project.

Notes for assessments:

1. You cannot pass this course unless you achieve a mark of at least 40% in each of the mid-semester test and the final exam. A student who narrowly fails to achieve 40% in either the test or exam, but who performs very well in the other, may be eligible for a pass in the course.
2. All assignments must be submitted by the due date. Late submissions will not be accepted. If a student is unable to complete and submit an assignment by the deadline due to personal circumstances beyond their control they should discuss this with the lecturer involved as soon as possible.
3. It is important to remember that copying another person’s work, and submitting that work as your own is plagiarism. This practice is unethical and may result in disciplinary action being taken against you. For assignments that are done in groups, it is important that all students in the group play an equal role in completing the assessment.
4. Students repeating the course must undertake all parts of the course
