Development of a methodology to assess functional performance of the Dutch Rhine: A case study on the impact of autonomous trends and sediment management strategies

The summer and autumn of 2018 showed the negative effects of both low-flow conditions and bed degradation over the last century on the river functions of the Dutch Rhine. These resulted in record-breaking water levels, extreme low navigation depth and subsequently nautical problems. As climate change will increase the inter-annual variability of...

Reliability of willows for wave load reduction on river dikes: Design and maintenance principles for willow vegetation based on the quantified natural and knowledge uncertainties

Flood defenses are important to keep large parts of the Netherlands dry. These primary flood defences<br/>are every twelve years assessed on safety during the Dutch national safety assessment. In 2017, the new<br/>safety standards (WBI2017) were introduced. These stricter standards caused that in total 251 km of the<br/>primary flood defences...

Economic optimisation of multi layer flood safety: Applicability of the risk based optimisation process under sensitivity to uncertainties and budget constraints. Case study: Nyaungdon, Myanmar

Risk based economic optimisation of water safety measures is presently being implemented in the more developed countries, but offers potential for developing countries too. With a limited budget, every penny needs to be well spent. It is however questionable if this method fits the circumstances in developing countries. Sufficient data is needed...

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...

Upscaling coastal flood risk assessment - Insight into the uncertainty of a continental-scale model

During the last years, flood risk assessments at continental and global scales are emerging as useful tools for risk hotspot identification, support for international policy-making and harmonization of strategies for climate change adaptation. The emergence of these models comes to cover the growing demand for integrated, large-scale risk...

Identifying Delta Regions Most Vulnerable for Flooding: A Multiple Land Use Flood Risk Assessment for Australia

The global economical losses caused by flooding have increased over the last 50 years (IPCC, 2014; UNISDR, 2013). Deltares and HKV are developing new methods to quantify flood risk on a global scale. A Flood Risk Assessment Tool (FIAT) is used to performcalculations. The definition of risk is hazard x exposure x vulnerability. FIAT is able to...

Impact of recent changes in river management on maintenance dredging in the Waal river

Over the last centuries, Dutch rivers such as the Rhine have been heavily trained for the purpose of the safe discharge of water, sediment and ice, and navigability. After the notorious flood events of 1993 and 1995 along the Rhine, new large-scale river works were initiated, such as the Room for the River (RfR) programme, to increase flood...

Navigability of the river Waal

Invloed van onzekere morfologische effecten op maatgevende hoogwaterstanden langs de Waal

Stochastische voorspelling van morfologische ontwikkelingen in de Waal: Effecten van een nevengeul bij Nijmegen

In de huidige riviermorfologie worden veelal voorspellingen gedaan op basis van deterministische modellen. De morfologische en hydraulische reacties worden met enkele modelsimulatie met zorgvuldig gekozen invoerwaarden bepaald. Bij het opstellen van een model en het specificeren van modelinvoer en modelparameters worden echter vele onzekerheden...

Morphological response to large-scale floodplain lowering along the river Waal: A stochastic approach
