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…

Real-time information for flood event management

A flood warning system in Jakarta has been extended to include real-time data supplied through Twitter. The Jakarta Flood Early Warning System, J-FEWS, is based on Delft-FEWS. This is the first time that Deltares has…

Netherlands Hydrological Instrument

Monitoring and modelling of ecosystems

Autonomous trends, climate change and human activities are expected to have a significant impact on Dutch water management. In the context of the Delta Programme, Delta Scenarios have been drafted on the basis of long-term…

Rapid Assessment Model for Urban Water Supply

Water supply in urbanising deltas

The world population is expected to rise from 7 billion now to 9 billion in 2050, with the increase being concentrated in urbanised areas. More than half of the global population already lives in urbanised…

Monitoring crop yield anomalies in Indonesia

Water supply in urbanising deltas
