Job description

Overview

Well respected engineering consultancy is looking for a Water Resources Engineer with around 5 - 7 years experience in hydrological analysis and hydraulic analysis and designs, to join their Engineering Hydrology Division in Johannesburg.

Requirements

• BSc Eng (civil) / BEng (civil)
• Preferably MSc or MEng in Hydrology and Hydraulics
• 5 to 7 years’ relevant experience aligned with the responsibilities listed below
• Valid South African driver’s license.

Software

• General : Word, Excel, PowerPoint, Projects, AutoCAD (Civil 3D)
• Specialised : GoldSim, PCSWMM, HEC-RAS, UPFLOOD, WRSM2005, Flo-2D, QGIS / ArcGIS, ModelMaker
• Advantageous : Programming / coding experience (Visual Basic, Python)
• Experience in the development and assessment of water balances using GoldSim is a requirement for this position.

Duties and Responsibilities

To carry out hydrological analyses focused mainly on, but not limited to :

• Acquisition and processing of hydrological data (rainfall, runoff, evaporation)
• Hydrological parameters (e.g., MAP, MAE, MAR)
• Catchment delineation
• Surface water runoff calculations (e.g., MAR, seasonal and dry weather flows) 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

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 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
