Responsibilities include:

• Perform and/or review hydrological assessments for mining infrastructure, including mine sites, haul roads, access roads, camps, stockpiles, processing facilities, and other supporting infrastructure.
• Conduct catchment analysis to identify contributing catchment areas, drainage paths, flow characteristics, and potential areas of flooding or water accumulation.
• Assess rainwater runoff from natural and developed catchments and determine peak flow rates, runoff volumes, and appropriate design criteria.
• Undertake rainfall analysis, including selection of appropriate design rainfall intensity, duration and frequency (IDF) and relevant return periods.
• Develop and review hydrological models and calculations for stormwater, surface water drainage, flood management, culverts, channels, diversion drains, detention ponds, and other water management facilities.
• Review and assess drainage strategies to manage runoff from mining areas and surrounding catchments, minimizing the risk of flooding, erosion, sedimentation, and damage to infrastructure.
• Provide technical input into the sizing and design review of culverts, open channels, drains, diversion structures, retention/detention ponds, spillways, and stormwater management systems.
• Review engineering deliverables, calculations, drawings, specifications, reports, and technical submissions prepared by EPC contractors, design consultants, and other project parties.
• Provide hydrology input to the design of roads, bridges, culverts, crossings, earthworks, and other mining infrastructure.
• Review the impact of changes in land use, topography, mine development, and infrastructure layout on catchment characteristics and rainwater runoff.
• Identify potential hydrological risks and recommend mitigation measures during design, construction, and operation.
• Coordinate with Civil, Geotechnical, Environmental, Water Resources, Mining, and Infrastructure Engineers to develop integrated water management solutions.
• Support PMC technical reviews, design coordination meetings, constructability reviews, and technical queries related to hydrology and drainage.
• Review contractor methodologies and proposals related to stormwater management, drainage, flood protection, and erosion control.
• Ensure hydrological designs comply with applicable Indonesian regulations, project standards, international standards, and client requirements.…
