Learning Outcomes:

Upon completion of this course, students should be able to:1. Understand the relationships between probability, risk and return period and their implications for design specifications2. Calculate the required design flood peak for any given return period and storm duration.3. Where appropriate, calculate the complete design hydrograph.4. Calculate the appropriate dimensions of a culvert or bridge opening to pass safely the design flood within the allowable freeboard5. Prescribe the most appropriate flood protection measures, either structural or non-structural, for a given situation.6. Prescribe appropriate SUDS measures for flood attenuation and water quality control in urban drainage systems.7. Using a computer model, compute the performance of the hydraulic flood protection measures in terms of water levels, discharges and risk (return periods) 8. Calculate the appropriate dimensions for the spillway, chute and stilling basin of a dam9. Understand the physical laws governing the generation and movement of water waves.10. Understand the effects of a shore on a deep water wave., including refraction.11. Calculate the height of wave runup on a shore12. Specify appropriate dimensions for a breakwater, including the type and size of protection material.13. Understand the principles governing the movement of plumes in water bodies14. Specify appropriate dimensions for sea outfalls and risers.
