Roads and railways in delta areas

The availability and reliability of infrastructure for for instance roads and railroads are vital for the transportation of people and goods in delta areas. On the other hand, infrastructure can have a major impact on sensitive habitats, and construction and maintenance can involve high costs.

Construction and asset management

Managers and builders of infrastructure in deltas have to work with soft subsurfaces and high water tables. Earth and groundwater behave unpredictably and that is a major cause of infrastructure failure. Furthermore, in large parts of the world, infrastructure is vulnerable to flooding, extreme precipitation and hazards such as earthquakes and landslides. Asset managers and contractors want to know what impact this will have on the costs, availability and reliability of their infrastructure projects. That requires an understanding of how soil and groundwater behaves, but also tools and methods.

Expertise

We provide answers to questions like:

  • How does infrastructure behave on soft soils? We focus in particular on settlement, vibrations, transition structures and structural stability.
  • How can geo-engineering risks during construction and management be expressed as project-specific risks such as costs and construction time?
  • What is the impact of climate change on infrastructure networks? Which adaptive measures are effective?
  • How can natural processes in soil and groundwater be used to build and manage infrastructure while minimising the impact on the surroundings?
