Coastal and River Structures

Design guidance for wave impacts on structures situated on top of a dike are typically developed for relatively deep water conditions. However, in Countries like Belgium, The Netherlands, the Adriatic coast in Italy and Germany…

ROBAMCI: a system-oriented and risk-based method for managing water infrastructure

Probabilistic Toolkit (PTK)

Rijkswaterstaat, water authorities and municipal authorities invest about 16 billion euros annually in the construction, management and maintenance of infrastructure such as roads, dikes, waterways, sewers, cables, pipelines and other engineering structures (Den Heijer, 2020). Approximately…

Climate change in relation to vector borne diseases – One Health PACT

Human health needs knowledge about water and the subsurface

Outbreaks of (new) infectious diseases in humans and animals are occurring more often and worldwide. That is linked to various factors, such as international trade and travelling, population growth and climate change. In the Netherlands,…

Sustainable decommissioning of offshore wind turbine foundations

Offshore (wind) energy

The limited lifetime of offshore wind farms requires an efficient and safe decommissioning. The project Hydraulic Pile Extraction Scale Tests (HyPE-ST) studied the option of removal of offshore wind turbine foundations (monopiles) in a sustainable…
