Drainage & Storm Water Modeller

Role Summary The Drainage & Storm Water Modeller will be responsible for planning, analysis, design, and hydraulic modelling of urban drainage and storm water systems. The role involves developing hydrologic and hydraulic models, assessing flood risks, evaluating drainage infrastructure capacity, and supporting resilient storm water management solutions for urban, airport, industrial, and infrastructure projects. Key Responsibilities • Develop, calibrate, and validate storm water and drainage network models. • Perform hydrologic and hydraulic analyses for storm water management, urban drainage, and flood mitigation projects. • Assess existing drainage infrastructure capacity and identify system deficiencies. • Conduct catchment delineation, runoff estimation, and flood routing analyses. • Evaluate the performance of pipes, channels, culverts, detention ponds, retention basins, and pumping stations. • Simulate various rainfall and climate scenarios to assess flood risks and network resilience. • Prepare drainage master plans, flood mitigation strategies, and storm water management plans. • Integrate GIS, survey, LiDAR, DEM, and utility data into hydraulic models. • Analyze model outputs and prepare flood inundation, surcharge, and capacity assessment reports. • Coordinate with hydrologists, GIS specialists, civil engineers, and urban planners.
