AIMS

This course explains some fundamental principles necessary for understanding the common water issues in the world. It covers the basic topics in practical hydrology, civil engineering hydraulics, turbulent mixing, and water/waste water treatments. It allows students to grasp essential concepts and procedures for analysing the hydro-environmental processes and develop skills to solve practical water engineering problems. It highlights some of the most pressing water-related global challenges, such as freshwater scarcity, soil erosion, water quality deterioration and flooding, and stresses the need for sustainable and integrated management of water resources.

OBJECTIVES

On completion of the course students should comprehend the scope of water-related topics in civil and environmental engineering. In particular, they should be able to:

Hydrology

• Appreciate the environmental, social, political and economical implications of water engineering
• Understand the hydrologic cycle and the Earth’s water budget
• Understand simple models of infiltration
• Undertake simple rainfall-runoff calculations over small catchments

Open Channel Flows, Pollutant and Sediment Transports

• Acquire a general understanding of river hydraulics
• Be aware of a wide range of hydro-environmental issues
• Understand the advective, diffusive, dispersive and decay processes related to pollutant transports in uniform flows
• Evaluate the impact of large hydraulic engineering projects
• Solve steady flows using the equations of mass, energy and momentum conservations
• Analyse unsteady flows using the method of characteristics
• Explain the cause of soil erosion and mitigation measures
• Understand the mechanism of sand particle motion
• Calculate the sediment transport rate and determine the bed regime
• Select pipeline systems for the conveyance of water supplies
• Make appropriate pump selections and design simple pumping systems

Water/Waste water Treatments

• Be aware of the principles and elements of water/wastewater treatments and the key engineering variables for their design
• Notice the limitations of the traditional water supply and sewage treatment systems in a sustainability context
