Hydraulic Engineer

Key Responsibilities

- Review hydrological and hydraulic studies for dams and related infrastructure projects.
- Analyze rainfall, runoff, flood, catchment, topographical and geological data.
- Undertake hydrological assessments to establish design floods and inflow hydrographs.
- Assess flood severity, frequency and long-term probability, including 100-year events and other required design scenarios.
- Develop, calibrate and validate rainfall-runoff and hydraulic models.
- Model catchment flows, reservoir routing, spillway discharge, downstream flooding and channel capacity.
- Assess the hydraulic performance and adequacy of spillways, outlets, gates, culverts, channels and energy-dissipation structures.
- Review reservoir levels, operating rules, storage capacity and flood-routing performance.
- Conduct flood-hazard, inundation and dam-break modelling where required.
- Prepare and review flood-inundation maps and identify areas, communities and infrastructure exposed to risk.
- Evaluate the potential effects of sedimentation on reservoir storage and hydraulic performance.
- Review survey data, digital elevation models, catchment boundaries and model inputs.
- Verify hydrological and hydraulic assumptions, calculations, boundary conditions and modelling results.
- Perform sensitivity, uncertainty and scenario analyses to validate study conclusions.
- Recommend optimum flood-control, water-management and risk-reduction solutions.
- Identify hydraulic deficiencies and propose rehabilitation, capacity-improvement or operational measures.
- Provide technical input to dam operating rules, reservoir-management plans and emergency action plans.
- Review consultants’ and contractors’ technical submissions, calculations, designs, drawings and reports.
- Confirm that studies and designs comply with applicable standards, Client requirements and recognized international practice.
- Coordinate with dam, civil, structural, geotechnical, environmental, mechanical, electrical and risk specialists.
- Support field investigations, inspections, data collection, instrumentation review and model verification.
- Maintain organized hydrological and hydraulic datasets, models, assumptions and technical records.
- Prepare clear daily, weekly, monthly, annual and technical reports as required by the assignment.
- Present modelling results, flood risks, technical conclusions and recommended actions to senior stakeholders.
- Coordinate with government stakeholders, consultants, contractors and multidisciplinary teams.
- Attend meetings, inspections and site visits anywhere in Saudi Arabia as required.
- Comply with Saudi laws, applicable codes, Client procedures, quality requirements and occupational health and safety obligations. Minimum

Requirements:

- Bachelor’s degree in Civil Engineering, Water Resources Engineering, Hydraulic Engineering, Environmental Engineering or another relevant discipline from a recognized university.
- Minimum 16 years of professional experience preparing hydrological and hydraulic studies and analyzing rainfall, runoff and flood data.
- Substantial experience working on dams, reservoirs, water resources or major flood-management projects.
- Demonstrated experience in catchment modelling, flood-frequency analysis, reservoir routing and hydraulic assessment.
- Advanced practical experience using HEC-HMS, HEC-RAS and SWMM, or equivalent hydrological and hydraulic modelling software.
- Experience assessing flood events, spillway capacity, downstream impacts and flood-risk-reduction alternatives.
- Ability to interpret topographical, geological, meteorological, hydrological and hydraulic information.
- Experience reviewing technical studies, calculations, model files, engineering drawings and consultant submissions.
- Strong technical-reporting, analytical, presentation and stakeholder-coordination skills.
- Relevant experience must be supported by verifiable employment records, project references, reports, models or studies when requested.
