New Delta research of groundwater reserves deltaic areas worldwide

Good fresh water supplies needed to safeguard prosperity and well-being

Recently, NASA warned that ‘the largest underground water basins in the world are disappearing at an alarming rate’. This is bad news: drinking water supplies, food production and industry depend on fresh groundwater. Together with…

Sound management and maintenance for older asphalt revetments

The Netherlands has approximately 600 kilometres of dikes, and sea dikes in particular, that are covered with asphalt. Something like 70% of those dikes are now older than thirty years. The assessment conducted every five…

Coincidence analysis for the Noorderzijlvest water authority

The conjunction of high outer water levels at sea with extreme rainfall (in other words, ‘coincidence’) can represent a problem for the drainage of polder and canal systems in the Dutch coastal area. Using models,…

ForeShore: soft solutions – certain safety

Worldwide, hard structures are used as coastal protection measure. These structures are static and do not respond to changing boundary conditions like sea level rise and increasing storminess. Moreover, the energy released during extreme events…

In the Perk Polder in Zeeland (NL), a new tidal and nature area is being built outside the dike on behalf of Rijkswaterstaat: 75 hectares of salt marshes and mud flats are being added to…

Flooding projections for oil palm plantations in the Rajang Delta peatlands, Sarawak, Malaysia

Land subsidence is one of the world’s underrated problems

Deltares experts are investigating how deforestation and drainage of tropical peatlands in Sarawak, Malaysia will cause subsidence in the future. Subsidence leads to increased water management problems and flooding. Since peat is not ‘land’ in the…
