Zijlstra, Wouter (author)
The Dutch Rhine-Meuse delta is expected to require many dike reinforcements on a short and long term, due to (accelerated) sea level rise. Average damage in unembanked areas will increase too, and a costly replacement of the Maeslantkering is expected after 2070. Delta21 is a project that aims to address these challenges related to flood...

Godlewski, Gabriela (author)
The combination of climate change and increased urbanization has resulted in cities with no historic flooding experience suddenly vulnerable to extreme flood events. Climate change increases the frequency and intensity of rainfalls, whereas urbanization decreases the total porous surface area, resulting in pluvial (rainwater) flooding. One such...

The flooding of the River Geul in July 2021 was an eyeopener for the society, the government and many others involved. Besides the major structural damage as a consequence of the flooding, the emotional damage was and still is massive. Therefore, the need for measures to reduce the impact of these extreme events is bigger than ever. Many people...

Ziere, Joost (author)
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...

This thesis is the first attempt in modeling Sennacherib’s (Neo-Assyrian king) colossal watercourse networks, with its main goal to uncover their hypothetical functionalities and operation, regarding irrigation needs and harvest yield production. Their total length surpasses 150 Km and was completed in four stages, with lack of data forcing...

Efficient and accurate streamflow predictions are important for urban water management. Data-driven models, especially neural network (NN) models can predict streamflow fast, while the results are uncertain in some complex river systems. Physically based models can reveal the underlying physics, but it is relatively slow and computationally...

Decision-makers in low-lying coastal zones are confronted with uncertain developments around flood risk.These drivers are surrounded by large uncertainties, which requires delta management to be adaptive. This research offers insights about adaptive delta management for the Rhine-Meuse estuary from three perspectives: a physical, a socio...

This work investigates the applicability of an analytical method for quick assessments of the long-term morphological effects of different dam operations on downstream river reaches with the idea to apply the method in feasibility studies to identify the least morphologic-impacting operation scenario. The Ribb River (Ethiopia) is used as a...

Overduin, Maarten (author)
In the past years, climate change has caused an increasing number of extreme weather events. In the Netherlands this is, for instance, reflected by the growing amount of extreme rainfall events. This creates big issues for water management authorities like water boards. Water boards are often responsible for local streams, that cannot handle the...

Agragrians in the Dutch Wadden sea region struggles with salinizing farmlands. Acacia Water's project Spaarwater enabled agrarians to measure salt concentrations in the ditches of their land using their mobile phone. All these measurements would ideally be used to evaluate the effects of salinization mitigation measures and to predict water...

Daniëls, J. (author)
An estuary forms the transition between the ocean/sea and a river. Within its boundaries salt and fresh water mix. Fresh water intake points may be located within the reach of salt intrusion. In order to justify political and managerial decisions it is thus necessary to understand and be able to predict the process of salt intrusion in estuaries...

In Walla Walla, Washington the Mill Creek flows through an outdated concrete spillway that needs renovation. The city council of Walla Walla saw this as an opportunity to further develop this channel. Their desires include conservation of the fish ladder, enabling to sail by boat and to prettify the spillway. A Sobek 1D model was built to give a...

Rongen, G.W.F. (author)
The Belgian Meuse is a river with a relatively low flood risk. The floodplains are narrow, and the estimated impact is not large until the flood reaches a magnitude of a once in a 200 years event. Flooding along the Belgian Meuse could however have an effect on the flood safety in the Netherlands, since there the flood defences are dimensioned...

Doets, I.J.E. (author)
Controlling the distribution of water and sediment at river bifurcations is one of the main challenges in river engineering and management. This distribution affects the stability of river bifurcations as well as the distribution of flooding risk, navigability and environmental conditions. The governing factors are the hydrodynamics of the two...

The Thua Thien-Hue province is located in the centre of Vietnam. It is characterized by the short distance between the mountains in the west and the coast of the South China Sea in the east. Two large rivers flow through the province, fed by multiple smaller rivers from the mountains. The Bo River flows through the northern part of the province...

Her en der worden in Nederland in beken en kleine rivieren vispasseerbare kunstwerken aangelegd om vismigratie mogelijk te maken en de ecologie van het systeem te verbeteren. Een veel voorkomende vispassage is de zogenaamde vispasseerbare stortsteen-bekkenpassage, ook wel cascade vistrap genoemd. Cascade vistrappen kunnen een opstuwende werking...

De Jongste, A.L. (author)
The area of the Merwedes is a transition zone between a tide-dominated area and a river-dominated area. With increasing river discharge, the influence of river flow dominates in this part of the Rhine-Meuse Delta. The composition of the river bed of the Merwedes is also a transitional area, because of the presence of both sand and mud. It is...

In opdracht van Vitens is in 2005 een koppeling ontwikkeld op basis van de modelcodes van Modflow en Sobek. Deze koppelingssoftware is getest in pilot gebied Wierden, onderdeel van het Regge-stroomgebied (Gehrels en Hakvoort, 2005). De resultaten van de test wezen uit dat de ontwikkelde software een krachtig instrumentarium is dat inzetbaar is...

Coastal zones which are known as the interface between continents and oceans are vital and important to human beings because a majority of the world's population live in such zones (Nelson, 2007). Coastal systems are among the most dynamic and energetic environments on earth and they are continuously changing because of the dynamic interaction...
