DRIHM: Distributed Research Infrastructure for Hydro-Meteorology

Predicting weather and climate and its impacts on the environment, including hazards such as floods and landslides, is still one of the main challenges of the 21st century with significant societal and economic implications. At…

AquaFit4Use: reducing fresh drinking water usage and promoting water reuse in industry

AquaFit4Use is an EU FP7 project aimed at reducing fresh drinking water usage and promoting water reuse in industry. Within AquaFit4Use 37 project partners work together to develop new technologies and methods for sustainable production,…

Bubble screen separates salt and fresh water

Freshwater Scarcity

Fresh water is precious, so contamination by salt water should be prevented as much as possible. Deltares, Royal Haskoning and Rijkswaterstaat have developed an innovative system that almost completely prevents the penetration of salt water…

The governance of smart combinations: Rules for collaboration on flood-risk mitigation

Smart Delta Governance

Changing the approach to flood-risk policy (in other words, introducing a range of measures to mitigate flood risks) implies taking a new look at governance in order to create more opportunities for a customised regional…

The Implementation of Adaptation: Flexible governance arrangements: obstacles and opportunities

Smart Delta Governance

The climate is changing. The awareness that adaptive measures are required is becoming increasingly widespread among government authorities, NGOs and market players. Obstacles such as a lack of urgency, budget cuts and conflicting interests do…

Characterisation and visualisation of the subsurface

FRESHEM Zeeland (FREsh Salt groundwater distribution by Helicopter ElectroMagnetic survey in the Province of Zeeland) is a study programme involving Deltares, TNO and BGR (the Bundesanstalt für Geowissenschaften und Rohstoffe). This project looks at where…

Freshwater availability in the Delta Programme

Freshwater Scarcity

The Freshwater Delta Decision, which is part of the Delta Programme, was drafted to ensure that adequate supplies of fresh water will continue to be available, now and in the future, for essential services such…

Using satellite data for a nationwide estimate of rainfall recharge in New Zealand

New Zealand and Australia

In many parts of New Zealand, rainfall directly recharges shallow and unconfined aquifers. Measurements and calculations of rainfall recharge (‘recharge’) are considered important since they help policymakers to decide on volumes of groundwater allocation. However,…

Scholte Waves

Characterisation and visualisation of the subsurface

Deltares regularly conducts marine seismic surveys. A recent development involves using Scholte waves to measure the stiffness of the seabed, an important parameter in many offshore and nearshore projects such as the construction of wind…
