Drainage Planning Expert

This role is for one of the Weekday's clients

Min Experience: 2 years

Location: Remote

JobType: full-time

The Hydrologist / Drainage Planning Expert will be responsible for leading hydrological, hydraulic, and stormwater drainage design activities across infrastructure, transportation, water resources, and urban development projects. This role involves rainfall–runoff analysis, watershed assessment, hydraulic modelling, flood-risk evaluation, and the design of efficient drainage systems. The position requires close collaboration with multidisciplinary teams and the ability to deliver engineering-ready reports, drawings, and data-driven solutions using survey and geospatial datasets.

Requirements:
Key Responsibilities

• Perform rainfall–runoff analysis using standard hydrological and statistical methods.
• Conduct catchment and watershed delineation, infiltration analysis, and runoff estimation.
• Analyze rainfall, discharge, and historical flood data to assess flood risks.
• Develop and validate hydraulic models using tools such as HEC-RAS, HEC-HMS, SWMM, or equivalent software.
• Design stormwater drainage infrastructure including channels, culverts, cross-drainage works, and outfall structures.
• Prepare GL–IL drawings, drainage profiles, hydraulic grade line calculations, and design documentation.
• Integrate geospatial and survey datasets including LiDAR, DEMs, drone imagery, and topographic surveys.
• Identify drainage constraints and bottlenecks and recommend mitigation and improvement measures.
• Prepare detailed hydrology reports, technical calculations, CAD drawings, and GIS-based deliverables.
• Coordinate with GIS, CAD, LiDAR, survey, and engineering teams to ensure data accuracy and consistency.
• Conduct field inspections and site validations for drainage and hydrological assessments.

Key Performance Indicators (KPIs)

• Accuracy and reliability of hydrological and hydraulic analyses.
• Quality, completeness, and engineering readiness of drainage designs and reports.
• Timely delivery of drawings, models, and technical documentation.
• Reduction in design rework through effective data integration.
• Client acceptance of deliverables with minimal revisions.
• Strong coordination across multidisciplinary teams.

Skills & Competencies

• Strong foundation in hydrology, hydraulics, stormwater management, and drainage planning.
• Hands-on experience with modelling tools such as HEC-RAS, HEC-HMS, SWMM, MIKE, or similar platforms.
• Proficiency in GIS tools (ArcGIS / QGIS) for terrain analysis and watershed modelling.
• Ability to interpret LiDAR data, DEMs, and topographic survey information.
• Working knowledge of AutoCAD or Civil 3D for drainage and infrastructure drawings.
• Strong analytical, problem-solving, and technical documentation skills.
• Effective communication and report-writing abilities.

Educational Qualifications

• M.Tech / M.Sc in Hydrology, Water Resources, Civil Engineering, or Environmental Engineering.
• B.Tech in Civil Engineering with strong hydrology and drainage experience may also be considered.
• Certifications or formal training in hydraulic and hydrological modelling tools are preferred.

Experience Requirements

• 3–12 years of experience in hydrology, drainage planning, stormwater modelling, or water resources engineering.
• Experience working with LiDAR- or drone-derived datasets is an added advantage.
