• Good understanding of surface water management, particularly in a mining and
industrial context
• Working knowledge of legislation, regulations and guidelines pertaining to water
management in the mining and industrial context
• Demonstrated project management skills
• Word, Excel, PowerPoint, Projects, AutoCAD (Civil 3D), PCSWMM, HEC-RAS,
UPFLOOD, WRSM2005, Flo-2D, QGIS/ArcGIS, ModelMaker
• Programming / coding experience (Visual Basic, Python)
• Experience in the development and assessment of water balances using GoldSim
Preference to candidates with the following skills and attributes:
• BSc Eng (civil) / BEng (Hons) (civil)
• Professional Engineer Registration
• Good critical thinking and problem-solving skills
• Good communication skills, fluent in English
• Dynamic, self-motivated, takes responsibility and ownership of tasks
• Able to manage time effectively
• Attention to detail
The main duties associated with the position include the following:
Hydrology:
The candidate will be required to carry out hydrological analyses focused mainly on, but not limited to:
• Acquisition and processing of hydrological data (rainfall, runoff, evaporation).
• 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
Hydraulics:
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
modelling).
• 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
calculations).
• Energy dissipating and erosion control structures.
• Dam break analysis.
Salary package:
Market related salary including company benefits, dependent on individuals experience and qualifications.
