Lambach, Jan Willem (author)
The Meuse river has been made navigable for ships by the construction of a cascade of seven weirs. At only two weirs hydropower facilities exist. This implies the full hydropower potential of the Meuse cascade is not utilized. Rijkswaterstaat only provides additional permits when fish friendly turbines are used. By using pump-turbines the river...

Banks constitute important areas for the river ecology since they provide a multitude of favourable conditions for flora and fauna. The hydromorphological diversity typical of these transitional zones between water and land, and the associated processes of erosion and accretion, make riverbanks vital for many aquatic and riparian plants and...

River floods are becoming increasingly devastating because of climate change (more frequent and extreme rainfall), population growth and the increasing economic importance of river basins. This situation requires maintenance and strengthening of flood-defence systems.<br/><br/>Adding certain types of vegetation at precise locations for their...

Almost a decade ago, the Mexican government targeted to establish environmental water reserves (EWR)—a volume of water allocated for ecological protection based on the Environmental Flow Mexican Norm (eflows, NMX-AA-159-SCFI-2012, ratified in 2017)—in strategic low-pressured for water use and high conservation importance river basins throughout...

Rivers provide many of our day-to-day needs. They allow, for instance, the production of drinking water and the movement of goods via inland waterways. However, river systems experience disturbances, such as droughts and pollution plumes. These disturbances can impair the functioning of river systems and their ability to provide the desired...

Sediment nourishments have become an increasingly attractive alternative to deal with continuous bed degradation problems in the river system. When supplied to the river, sediment nourishments induce a sediment wave that propagates through the system causing changes in bed level and bed surface texture. In the present study we use a one...

The research aims to provide an understanding of an urbanizing delta in which different scales, times, and domains are related to each other; and to examine how this understanding can be used in a planning and design process in a rapidly urbanizing delta. A mapping method is developed according to the key notions in the understanding of urban...

In the Waal bed degradation occurs, which is mainly induced by a large number of river regulations measures done in the past. Rijkswaterstaat develops possible measures and new techniques to stop riverbed erosion and/or mitigate the negative effects. One of the possible new techniques to reduce riverbed erosion locally is groyne field...

Curran, A.N. (author)
Flood risk analysis focused on small sections or regions of embanked systems ignores the dy-namics of large-scale floods through time and space. Resulting measures are oftentimes inef-ficient due to an over estimation of risk or be-cause they simply transfer risk downstream due to increased localised protection upstream. This present work...

Irving, Meghan (author)
Flexible river training structures such as tetrahedron frames (`porcupines') can be attractive for control of braided river channel networks in regions where permanent control structures (e.g. groynes or dams) are too expensive or potentially inefficient, such as systems with highly dynamic flow regimes and morphology. Porcupines provide...

Research about the covered river Senne in Brussels. This former river seems to be invisible, but this research shows that this former industrial river still lives in the city (within the architecture and the urban structure). What can a revitalization of this covered river mean? And how does architecture relate to this revitalized space?

Ice jam events can be devastating for the environment, human infrastructure, and local population. During breakup season, it is of great importance to be informed about the river ice cover condition in order to mitigate breakup flood risk. The Athabasca River near FortMcMurray, located in Alberta, is particularly prone to ice jam events and...

Conventional dike reinforcement measures do not take vegetation into account, while vegetation contains wave damping properties. Reasoning for this is that vegetation in general is seen as temporary and hence may be removed in the future. In this case study for the Dutch waterboard WDOD, the wave damping properties of vegetation in a floodplain...

TheAmazon-Orinoco river plume is a buoyant freshwater lens of 1.2 × 10<sup>6</sup>km<sup>2</sup>, which has been traced over 2000 km from the Amazon river mouthinto the Caribbean Sea and along the Lesser Antilles. The river plume iswarmer than the surrounding open-ocean waters, with temperaturedifferences up to 1.5 ∘C caused...

This research focuses on using Sentinel-2 optical imagery to provide a means of high-resolution monitoring and evaluation of changes in Total Suspended Matter (TSM) concentration in the Brantas river basin. In situ spectral measurements as well as laboratory results show an extremely turbid nature of the Brantas River surface water. Current...

Large shallow lakes plays a significant role in the rapid urbanization process. A series of problems have occurred due to urbanization including water quality degradation, flood intensity increase, ecological and environmental issues etc. One of the most important threat comes from eutrophication, as it deteriorates water quality, introduces...

The phase “water, water everywhere but too much or too little” aptly explains the current situation of many global cities. Within the numerous challenges due to Climate change and Urbanisation, water ranks the highest as a risk to the society. This risk ranges from water related catastrophes like floods to availability of portable water to the...

This project seeks for an alternative low-cost housing strategy for the city of Addis Ababa, Ethiopia. Currently, the condominium housing scheme is implemented everywhere throughout the city. Despite the impressive amount of newly constructed dwelling units, shortcomings of this housing strategy have drastic consequences within the social and...

The Meuse river facilitates important socio-economic functions. In the light of Integrated River Management (IRM), the question rises whether these functions can be facilitated in future decades (until 2050) as well. The riverbed is expected to degrade over the coming decades, just like in the past century. On top of that, the discharge regime...

The capitalistic and economy driven approach towards urbanization in India has led to a great disparity between different socio-cultural groups as well as a huge pressure on the ecological systems. Further, with the changing climate these groups are increasingly vulnerable to hazards. This can be observed even in the Ganges River Basin where...
