Job Description / PURPOSE:
The Hydrologist will be responsible for conducting a comprehensive stormwater, hydrology and flood risk assessment at the Mine. The role includes site assessments, advanced hydrological modelling, stormwater master planning, flood hazard analysis and the development of a conceptual Stormwater Management Plan aligned with Anglo-American and DWS best practice guidelines across current, planned and closure phases of the mine
EXPERIENCE AND SKILL REQUIREMENTS:
Proven expertise in hydrology, hydraulics, stormwater master planning and flood risk assessment
Advanced modelling capability using industry-preferred hydrology and hydraulic software
Experience in training and technical modelling methodologies
Registered with ECSA as a Professional Engineer (Pr Eng)
Relevant tertiary qualification in Hydrology
Experience within mining or large industrial environments highly advantageous
DUTIES AND RESPONSIBILITIES:
The successful candidate would be required, but not limited to:
Conduct site visits including inspection, data collection, sampling and measuring of stormwater infrastructure
Verify topographic and survey data and develop a detailed status quo assessment for modelling purposes
Identify and document all man-made structures influencing stormwater runoff (roads, rail, embankments, etc.)
Identify survey data gaps and develop additional field survey plans where required
Develop layout plans of existing stormwater infrastructure and planned/pipeline stormwater projects
Compile a detailed technical memorandum including photographs, findings, problem areas and infrastructure schedule
Delineate catchments considering life of mine plans and clean/dirty water separation
Evaluate adequacy of onsite climate monitoring network
Develop intensity-duration-frequency rainfall curves using latest rainfall data and climate change considerations
Characterize hydrology, topography and runoff for various life-of-mine scenarios including closure
Develop a conceptual Stormwater Management Plan (SWMP) for current, planned and closure phases
Conduct flood hazard evaluation using rain-on-grid/direct rainfall modelling methods
Produce site flood maps in line with AA TS 602 104 standards for various rainfall scenarios
Evaluate adequacy of existing stormwater and flood control infrastructure (culverts, berms, trenches, sumps, pumps, etc.)
Provide flood and sedimentation risk exposure summary with supporting technical memorandum and presentation.
Provide maps in KMZ, PDF and shapefile formats and share model input files with client.
Facilitate a one-day risk assessment workshop aligned to the AA integrated risk rating matrix guideline
