Design Engineer- Hydraulics

Role & responsibilities

1. Hydrological & Water Resource Analysis

• Conduct

  water availability studies

  to determine firm and secondary energy potential.
• Perform

  power potential studies

  to optimize plant capacity and energy output.
• Execute

  flood studies

  , including:
• Hydrograph analysis, Unit Hydrograph development, and Peak Flood Estimation.
• Flood Frequency Analysis (Annual/Partial Duration Series) to determine

  Standard Project Flood (SPF)

  and

  Probable Maximum Flood (PMF)

  .
• Reservoir and Channel Flood Routing.
• Lead

  reservoir sedimentation studies

  to forecast long-term siltation, establish new zero elevations, and assess project lifespan.

2. Planning & Conceptual Design

• Develop initial ideas and concepts for the

  planning and designing of Hydro projects and PSP

  .
• Define the

  general layout of the water conductor system

  (intakes, tunnels, penstocks, surge shafts, tailraces).
• Conduct

  reservoir planning

  , including establishing various reservoir zones and developing Area-Elevation and Storage-Elevation curves.
• Create

  initial filling plans

  for new reservoirs.
• Plan

  river diversion arrangements

  , including coffer dams and diversion tunnels/channels.

3. Detailed Hydraulic Design & Analysis

• Review and perform preliminary hydraulic designs for all hydraulic structures:
  
• Dams, Barrages, Intakes, and Water Conductor Systems.
• Spillways, Energy Dissipation arrangements (e.g., plunge pools, stilling basins), and Desilting Chambers.
• Surge Shafts/Tanks and Transient Analysis for system stability.
• Cross-drainage structures (Bridges, Culverts), Guide Bunds, and Flood Protection Embankments.
• Perform critical calculations including:
  
• Head loss calculations for waterways.
• Uplift pressure calculations for structures.
• Soil and Rock Scour calculations.
• Depth of cut-off and design of protection works.
• Water surface profiles in rivers.
• Design comprehensive drainage systems for project areas and powerhouse drainage.

4. Numerical Modeling & Simulation

• Conduct

  1D and 2D numerical analysis

  in

  HEC-RAS

  for flood modeling, dam break studies, and water surface profiles.
• Perform advanced

  3D numerical analysis

  in software like

  Flow-3D Hydro

  for complex flow patterns, sediment transport, and structure interaction.
• Carry out

  transient analysis

  using software (e.g.,

  WHAMO

  ,

  Hammer

  ) to design and optimize surge shafts/tanks and protect the pipeline system.
• Formulate numerical models, run simulations, and analyze results to identify and rectify design flaws.

5. Dam Safety & Risk Mitigation

• Conduct

  Dam Break Studies

  to model inundation maps and develop

  Flood Damage Mitigation

  plans.
• Perform verifications for key design levels (Top of Dam, Spillway invert, Intake invert) and structure sizes (Spillway bays).
• Ensure designs meet all safety guidelines for selecting design floods and return periods.

6. Integration & Collaboration

• Interface with geotechnical, civil, and mechanical teams to integrate hydraulic requirements.
• Understand

  topographic and bathymetric survey

  data and utilize

  Geographic Information Systems (GIS)

  for spatial analysis.
• Coordinate with and

  understand Physical Model Studies

  (hydraulic and sediment) to validate numerical models.
• Compare numerical and physical model results to refine designs and ensure accuracy.

7. Documentation & Reporting

• Prepare

  Design Basis Reports

  and detailed

  Hydraulic Design Reports

  .
• Perform

  quantity estimation

  for cost planning and tender documents.
• Document all analyses, assumptions, and conclusions for client and regulatory submission.
