Postdoctoral Opportunity 2026 | Surface Water Salinity Intrusion in the Ganges–Brahmaputra–Meghna Delta at TU Delft

Delft University of Technology (TU Delft) invites applications for a Postdoctoral Researcher position on Surface Water Salinity Intrusion in the Ganges–Brahmaputra–Meghna (GBM) Delta. This international research project focuses on understanding saltwater intrusion, estuarine hydrodynamics, and climate resilience in one of the world's largest and most climate-vulnerable delta systems.

Position Overview

About the Project

Increasing surface water salinity intrusion poses a significant threat to freshwater availability in estuaries and delta regions worldwide. This challenge is especially critical in the Ganges–Brahmaputra–Meghna (GBM) Delta of Bangladesh, where climate change, sea-level rise, altered river discharge, and human interventions are intensifying salinity intrusion.

This postdoctoral project aims to improve scientific understanding of salt intrusion processes and evaluate effective adaptation and mitigation strategies using advanced 2D–3D numerical hydrodynamic modelling. The research is conducted through an international collaboration involving TU Delft, Institute of Water Modelling (IWM), Bangladesh University of Engineering and Technology (BUET), Wageningen University & Research (WUR), and Deltares.

Key Responsibilities

The selected researcher will:

• Investigate saltwater intrusion mechanisms in the GBM Delta.

• Develop and apply advanced 2D–3D hydrodynamic models using Delft3D Flexible Mesh.

• Assess the impacts of sea-level rise, changing river discharge, reservoir management, land subsidence, cyclones, channel deepening, and land reclamation.

• Validate numerical models using observational datasets collected by project partners.

• Analyse residual circulation, tidal dynamics, and salt dispersion processes.

• Develop and evaluate climate adaptation and salinity mitigation strategies.

• Collaborate with international research partners and participate in field-related research activities, including visits to Bangladesh.

Research Focus Areas

The project includes research in:

• Estuarine Hydrodynamics

• Coastal Ocean Modelling

• Surface Water Salinity Intrusion

• Climate Change Adaptation

• Delta Management

• Numerical Hydrodynamic Modelling

• Delft3D Flexible Mesh

• Coastal Engineering

• Water Resources Management

• Environmental Fluid Mechanics

• Sea-Level Rise

• Salinity Mitigation Strategies

Eligibility Criteria

Applicants should possess:

• A Ph.D. in Civil Engineering, Coastal Engineering, Hydraulic Engineering, Ocean Engineering, Environmental Engineering, Water Resources Engineering, or a related discipline.

• Strong experience in numerical hydrodynamic modelling.

• Familiarity with estuarine or coastal processes and climate-related environmental modelling.

• Experience with tools such as Delft3D, or comparable hydrodynamic modelling software, is desirable.

• Excellent analytical, programming, and scientific communication skills.

• Ability to work effectively within multidisciplinary and international research teams.

Why Join TU Delft?

This postdoctoral opportunity offers candidates the chance to:

• Conduct internationally impactful research on climate resilience and delta management.

• Work with leading experts from Europe and Bangladesh.

• Apply state-of-the-art numerical modelling tools to real-world environmental challenges.

• Contribute to sustainable water resource management in one of the world's most vulnerable delta regions.

• Access world-class research facilities and international collaboration opportunities.

How to Apply

Interested candidates should submit their application through the official TU Delft careers portal, along with all required academic documents and supporting materials as specified in the official vacancy announcement.
