Mitigating the effect of drought on groundwater levels in the east of The Netherlands: The link between interventions in the Rhine river branches and a closure of the Rijnmond

Due to climate change, a new water management policy is considered in the Netherlands. The shift towards greater extremes in both wet periods and dry periods requires a more dynamic policy. It is investigated what effect the placement of a permanent water barrier in the Rijnmond has on the water levels in the Rhine branches, and if this can be...

Assessment framework of actor strategies in international river basin management, the case of Deltarhine

The combined effects of socio-economic growth as well as climate change exert increasing pressure on international river basins and require dedicated cooperative efforts to jointly manage international rivers. Cooperative strategies drawn from scientific literature, empirical research and practitioner’s handbooks are explored and clustered...

The economic risk for inland water transport due to uncertainty in morphodynamic behaviour

River systems are vastly changing environments, not only due to natural process, but also human intervention plays an important role. With the many different river functions at play, large amounts of maintenance budgets are associated with river management. For decision makers it is important to know expected costs or losses and the spread...

Impact Assessment of the Rhine ROFI on the Annual Cross-shore Sand Transport

Using D-Flow Flexible Mesh numerical software to simulate the region of freshwater influence of the Rhine in front of the Dutch coast to assess the influence of stratification on the near-bottom velocities and the related cross shore sand transport.

Fit for purpose? Building and evaluating a fast, integrated model for exploring water policy pathways

Exploring adaptation pathways is an emerging approach for supporting decision making under uncertain changing conditions. An adaptation pathway is a sequence of policy actions to reach specified objectives. To develop adaptation pathways, interactions between environment and policy response need to be analysed over time for an ensemble of...

Engineering Cooperation?: The Contribution of Water Experts in Promoting Water Cooperation in the Mountain Aquifer (Israel – Palestine) and in the Rhine River Basin

Introduction Different water resources are shared among neighbouring nations worldwide, as water does not recognize any (political) boundaries. This fact has led to conflict and cooperation between neighbouring states over the management of such water resources. To manage these resources in a way that it prevents conflict and promotes...

Stroomgebiedbeheerplan Rijndelta

De Kaderrichtlijn Water heeft tot doel de oppervlaktewateren - waaronder ook overgangswater en kustwater - en het grondwater in de Europese Unie te beschermen en te verbeteren en het duurzaam gebruik van water te bevorderen. De doelstellingen van de KRW moeten op 22 december 2015 zijn bereikt. Deze termijn kan onder bepaalde voorwaarden worden...

Klimaatbestendigheid van de drinkwatervoorziening in Nederland gebaseerd op oppervlaktewater

Deltares werkt momenteel in opdracht van RWS-Waterdienst aan de opzet van het project "Klimaatbestendigheid van Nederland Waterland". In dit project wordt onderzocht wat de klimaatbestendigheid is van het hoofdwatersysteem van Nederland. In het project staan twee vragen centraal: 1. Waar liggen de omslagpunten die leiden tot een ander...

The impact of climate change on the water quality of the Rhine river

In this research the effect of hydrological extremes on water quality are studied for the Rhine River, in order to assess potential water quality effects of climate change. The water quality of the Rhine was studied for the periods 1975-1977 and 1987-2005. During these periods eight hydrological extremes occured, five of which being classified...

Waterkwaliteit van de Rijn en de Maas bij (extreem) lage afvoeren

De zomer van 2003 werd gekenmerkt door aanhoudend hoge temperaturen en lage rivierafvoeren. De effecten van deze droogteperiode op de waterkwaliteit zijn tot op heden niet diepgaand onderzocht. De algemene indruk is dat de effecten wel mee zullen vallen. In de "Evaluatienota Waterbeheer Aanhoudende droogte 2003"(Min. V&W, 2004) wordt ook met...

Development of flood management strategies for the Rhine and Meuse basins in the context of integrated river management

Water management of the rivers Rhine and Meuse is surrounded by major uncertainties. The central question is then: given the uncertainties, what is the best water management strategy? This raises the need for integrated scenarios that consider possible futures in a coherent and consistent way. Within the framework of IRMA-SPONGE a scenario study...

Evaluation of floodplain management strategies: The added value of wetlands

The objective of this project was to evaluate the beneficial effects of wetlands on flood risk reduction and water quality improvement in the Rhine. The analysis of wetland effects on flood risk reduction aimed at evaluating whether the position of a wetland in the basin – upstream or downstream – will influence the added value of the wetlands...

The canalization of the lower Rhine

A few kilometres after crossing the Dutch frontier the Waal splits off from the river Rhine and flows to the left carrying 70% of the Rhine's water. A few kilometres further down, the IJssel splits off and flows to the right carrying 12% of the water coming down the Rhine. The river Rhine turns to the left carrying the remaining 18% of its...
