Hydrologist

SUMMARY:
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

POSITION INFO:
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

• 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
