Rise and Fall: strategies for the subsiding and urbanising Mekong Delta (Vietnam) facing increasing salt water intrusion

The research aims to develop sustainable strategies for groundwater extraction and management, and to understand and quantify land subsidence and salt water inflow in the rapidly urbanising Mekong Delta in Vietnam.

Key audiences to be targeted during the research are:

  • Co-investigators in Vietnam (Can Tho University, Division for Water Resources Planning and Investigation for the South of Vietnam).
  • Water authorities who take decisions on the management of the resource.
  • Water managers, awareness promotors (national NGO’s, governmental organizations), educators, lecturers



The project aims to enhance the capabilities of individuals and organisations to develop sustainable strategies for dealing with groundwater extraction, land subsidence and salt water intrusion in the increasingly urbanising Mekong Delta (Vietnam). We will enlarge the knowledge base of stakeholder (including policymakers, water managers and scientists) and work with them to develop and implement innovative tools and technologies in practice and policy.

A new integrated delta model will be developed linking surface water, groundwater and geo-mechanical models, to analyse the interrelated character of groundwater extraction, subsidence levels and salt water intrusion. Together with stakeholders the integrated model will be constructed and applied to quantify the effects of water management strategies in the Mekong Delta. Stakeholders will analyse and develop adequate strategies by simulating and demonstrating the effects of development scenarios and policy recommendations, such as expressed in the Mekong Delta Plan (2013).
