Engineering Hydrology Department – Civil Engineer

  • Civil Engineer required to conduct hydrological and hydraulic analysis.
  • 3 to 6 years of experience in hydrology and hydraulics.
  • Gauteng (Rivonia).

Jones & Wagener is seeking to employ a Civil Engineer in the Engineering Hydrology department, based in the Rivonia office. The candidate will be required to carry out hydrological and hydraulic analyses as listed in the duties section below.

  • 3 to 6 years of experience in hydrology.
  • Experience in the development and assessment of water balances using GoldSim.
  • Bachelor’s degree in Engineering (BSc / BEng (civil)) or higher.

Preference to candidates with the following skills and attributes:

  • MSc or MEng in hydrology and hydraulics.
  • Good understanding of surface water management.
  • Working knowledge of legislation, regulations and guidelines pertaining to water management in the mining and industrial context.
  • Excellent written and spoken English, including technical report writing skills.
  • Demonstrated project management skills.
  • Programming / coding experience (Visual Basic, Python).
  • General software: Word, Excel, PowerPoint, Projects, AutoCAD (Civil 3D).
  • Hydrology related software: GoldSim, PC-SWMM, UPFLOOD, HEC-RAS, WRSM2005, Flo-2D.
  • Good critical thinking and problem-solving skills.
  • Good communication skills.
  • Dynamic, self-motivated, takes responsibility and ownership of tasks.
  • Works independently.
  • Attention to detail.

The main duties associated with the position include the following:


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.


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.
