Senior Hydraulic Modelling Engineer📣 إعلان

Role Overview

Euro Group Engineering is seeking a Senior Hydraulic Modelling Engineer to join its team in Riyadh. This full-time role involves leading advanced hydrological and hydraulic modelling for major stormwater drainage, flood protection, and urban flood resilience projects across the city. The engineer will support municipal drainage upgrades, wadi flood mitigation, and infrastructure development, ensuring alignment with the standards of RCRC, MOMRAH, NWC, and other Riyadh-based authorities.

Hydraulic Modelling and Analysis

• Develop and calibrate 2D and 1D/2D integrated hydraulic models using InfoWorks ICM and HEC-RAS.
• Model surface runoff, wadi flow behavior, culverts, tunnels, stormwater basins, and conveyance systems relevant to Riyadh’s terrain.
• Assess flood risks, inundation extents, flow velocities, and identify critical hazard zones across Riyadh’s urban and suburban areas.
• Conduct scenario analysis for extreme rainfall events typical to Riyadh’s climatic conditions.
• Provide modelling outputs to support concept, preliminary, and detailed design stages for municipal and mega-project infrastructure.

Flood Protection and Drainage Design

• Recommend flood mitigation solutions including diversion channels, retention/detention basins, berms, and flow-control structures.
• Support flood protection planning for wadis, new urban developments, and existing municipal areas within Riyadh.
• Conduct flood risk assessments aligned with Saudi authority requirements and international best practices.
• Design stormwater networks including pipes, manholes, traps, conveyance lines, and collection basins.
• Calculate hydraulic capacities, flow velocities, energy losses, and pressure conditions.
• Use ICM and SWMM models to evaluate network performance under varying storm conditions.
• Coordinate with civil, infrastructure, and supervision teams to ensure integrated and compliant designs.

Data Management and Terrain Development

• Process rainfall, flow, elevation, LiDAR, DEM, and GIS datasets relevant to Riyadh’s topography.
• Build accurate DTM/DEM surfaces and prepare terrain data for 2D flood modelling.
• Manage spatial databases and ensure data quality, consistency, and traceability.

Technical Reporting and Communication

• Prepare detailed technical reports covering modelling methodology, assumptions, results, and engineering recommendations.
• Present findings to clients, authorities, and internal teams with clarity and technical accuracy.
• Maintain documentation for model versions, calibration records, and scenario outputs.

Candidate Requirements

The ideal candidate will possess 5-10 years of experience in hydrological and hydraulic modelling, particularly within stormwater drainage and flood protection projects. Proficiency in modelling software such as InfoWorks ICM, HEC-RAS, and SWMM is essential. Candidates should demonstrate strong analytical skills for flood risk assessment, data interpretation, and the ability to provide data-driven engineering recommendations to multidisciplinary design teams.
