Engineering Hydrology – Water Resources Engineer: at Jones & Wagener

Job Summary 

We are currently looking for a self-motivated Water Resources Engineer to join our Engineering Hydrology department and contribute to new and existing projects. The successful candidate will join a dynamic team in a mid-level position, based in our head office (Rivonia) on a full-time basis. The engineer would carry out hydrological and hydraulic analyses and designs.

Preference to candidates with the following skills and attributes:

• MSc or MEng in hydrology and hydraulics.
• 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 requirements associated with the position are as follows:

• BSc Eng (civil) / BEng (civil).
• Five to seven years’ relevant practical experience.
• 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, GoldSim, AutoCAD (Civil 3D), PCSWMM, HEC-RAS, UPFLOOD, WRSM2005, Flo-2D, QGIS/ArcGIS, ModelMaker.
• Programming / coding experience (Visual Basic, Python).

 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.
