Hydrology Specialist

Job Purpose

Deliver independent hydrology and hydraulics reviews and studies for utility-scale solar and site development projects. Produce drainage and flood assessments that meet Philippine regulatory standards and client requirements, integrating outcomes with geotechnical and structural evaluations.

Key Responsibilities

• Conduct watershed delineation and rainfall–runoff modeling (e.g., HEC-HMS); perform 1D/2D flood routing and overland flow analysis (HEC-RAS).
• Assemble design storms using PAGASA RIDF data; develop design hyetographs and flood maps; document assumptions, losses, and return periods.
• Review contractor reports for methodology, calibration/validation, freeboard, and sensitivity; ensure alignment with DPWH drainage and flood control standards.
• Coordinate with Geotechnical and Structural teams on culverts, channels, scour protection, and platform drainage; issue redlines and acceptance criteria.
• Prepare Design Review Reports (DRRs), calculation notes, GIS layers/figures, and closure logs; participate in scheduled site walkdowns.

Key Deliverables

• Hydrology & Flood Study Report (including models, maps, data sources, and assumptions).
• Drainage and flood mitigation memo with options and recommendations.
• Red-lined drawings and a Design Review Report (DRR) with issue closure tracking.
