• Hydrological parameters (eg, MAP, MAE, MAR).
• Catchment delineation.
• Surface water runoff calculations (eg. MAR, seasonal and dry weather flows, etc.)
for site specific catchment areas.
• Flood peak runoff calculations (applying industry acceptable deterministic,
statistical, empirical and dynamic modelling methods).
• Water balance analysis and modelling (principles of conservation of mass,
including dam sizing).

• Reservoir and canal routing (dynamic water level analysis).
• Floodline determination.
• Surface water impact assessment.
• Flood risk and flood hazard assessment


The candidate will be required to carry out hydraulic analyses and designs, focused mainly on, but not limited to:
• Water surface backwater profiling (applying the principles to be used in floodline
• Flood attenuation (whether in reservoirs or upstream of culverts, applying the principles
to determine the attenuated volumes, reduced release peak flows, etc.)
• Canal flow (applying hydraulic theory and principles for free surface flow).
• Spillway design (hydraulic design and optimisation with flood routing and attenuation
• Energy dissipating and erosion control structures.
• Dam break analysis.
