CE74.51 : River Engineering and Modeling  3(3-0)
 
Course objectives:
The objective of this course is to provide students with knowledge and understanding of river hydraulics and sediment transport along with applications in designing of river engineering structures and hydraulic model development. Basic numerical methods for solving a range of practical engineering problems in river and reservoir are also introduced.
 
Learning Outcomes:
The student on completion of this course would be able to:
  • Identify characteristics of river flow and sediment transport, and how they regulate the river geomorphology;
  • Undertake river hydraulic analysis, water quality assessment, model selection along with application range, data requirement, model accuracy and stability;
  • Develop models for water flow, sediment transport and water quality in rivers and reservoirs;
  • Plan and design stable channels and river hydraulic works to control river flows and sediment transport; and
  • Develop simulation models for the streamflow, sediment transport and water quality in rivers and reservoirs.

Evaluation Scheme:
The final grade is computed according to the following weight distributions: Coursework assignment (10%), Group presentation and discussion (10%), Mid-semester exam (40%) and Final exam (40%). Open-book examination is given in both mid-semester and final exams.

An “A” will be awarded if a student can show an excellent ability of having elaborative knowledge of river hydraulics, sediment transport, channel morphology, river engineering works and numerical modeling of water quality and transport, sediment flows in rivers and reservoirs. A student is in this category will typically participate, and contribute, actively in the class discussions and presentations. Furthermore, the student has to fulfil all the requirements given in his/her assignments. A “B” will be awarded if a student shows an overall understanding of all the given topics. However, application of knowledge into practice is found wanting. A “C” will be given if a student is able to show satisfactory command over the subject matter. A “D” will be given if a student displays very limited knowledge of the subject matter, and does not appear motivated to learn new things.
