Moonen, Siirilotta (author)Hydropeaking is a widely applied management practice in the generation of hydropower. When the demand in electricity is high, the operator of a hydropower plant rapidly increases released discharges to meet this demand. Vice versa, when the demand is low, no or less water is released. However, while river regulation practices offer valuable...master thesis 2024

Samboko, H.T. (author)The unavailability of consistent accurate river flow data is a significant impediment to understanding water resources availability, and hydrological extremes. This is particularly true for remote, difficult to access, morphologically active and therefore rapidly changing rivers. The state of global river discharge monitoring with respect to...doctoral thesis 2023

(author), van der Meulen, Bas (author), Herget, Jürgen (author), Hulscher, Suzanne J.M.H. (author)Reconstructions of the most severe historic flood events contribute to improved quantification of design discharges corresponding to large return periods. Reducing the uncertainty of design discharges has a great significance in constructing proper flood defences to protect the hinterland from future flooding. However, reconstructions of the...journal article 2023

Sewberath-Misser, Vyasa (author)The coastal zone is becoming more vulnerable due to growing concentrations of human population, settlements, and socio-economic activities. The Rhine-Meuse Delta is low-lying land, which makes it vulnerable to flooding. The Maeslant barrier is a storm surge barrier which should prevent flooding in the low-lying land behind the barrier. Various...master thesis 2022

Sarisen, Dondu (author), Koukoravas, Vasilis (author), Farmani, Raziyeh (author), Kapelan, Z. (author), Memon, Fayyaz Ali (author)Intermittent water supply (IWS) is widely used around the world, and with the increase in population and predicted future water scarcity, IWS applications seem to continue. While most of the existing studies on water supply concentrate on continuous water supply (CWS), the research focused on the IWS is now becoming mainstream. Hydraulic...review 2022

Kingma, Vera (author)Human interventions in the White Volta River in Ghana increase the flood risk in living spaces of the local communities, causing great challenges in the area. Burkina Faso has built a hydropower dam near the border with Ghana which has a large impact on the discharge extremes of the White Volta River. As a result of poor water management of this...master thesis 2021

Schallwig, Lisa (author)Ancient Basrah has been the center of anthropological research studies due to its significance in the development of the culture, politics and economics of the region at the time. Agriculture was one of the main income revenues for ancient Basrah even though it received only an average of 60mm of rainfall per year, indicating a large reliance on...master thesis 2021

Kramer, O.J.I. (author)In drinking water treatment plants, multiphase flows are a frequent phenomenon. Examples of such flows are pellet-softening and filter backwashing where liquid-solid fluidisation is applied. A better grasp of these fluidisation processes is needed to be able to determine optimal hydraulic states. In this research, models were developed, and...doctoral thesis 2021

Jia, Yueyi (author), Zheng, Feifei (author), Zhang, Qingzhou (author), Duan, Huan Feng (author), Savic, Dragan (author), Kapelan, Z. (author)Hydraulic modeling of a foul sewer system (FSS) enables a better understanding of the behavior of the system and its effective management. However, there is generally a lack of sufficient field measurement data for FSS model development due to the low number of in-situ sensors for data collection. To this end, this study proposes a new method...journal article 2021

Srinivasa, Vibhu (author)Wastewater discharged from the domestic household has proven to be a potential source for resource recovery. Apart from wastewater, kitchen organic waste contains an enormous amount of energy in terms of organic content and nutrients such as TKN and TPH. Now that the disposal of waste into landfills is prohibited in most parts of Europe, one of...master thesis 2020

(author)Participatory modelling has become a growing concept in environmental modelling, as it allows stakeholders to be involved in various stages of model development. The majority of studies, however, have focused on the participation during model use for scenario analysis and strategy evaluation after the model has been developed.

(author)A novel effective drag relation for liquid-solid fluidisation is proposed, suitable for application in full-scale installations. This is achieved by presenting new insights related to the influence of the temporal-spatial heterogeneity on the effective hydrodynamic drag for large fluidised systems. While heterogeneous flow behaviour can be...journal article 2020

Curran, A.N. (author), de Bruijn, Karin M. (author), Klerk, W.J. (author), Kok, M. (author)To make informed flood risk management (FRM) decisions in large protected river systems, flood risk and hazard analyses should include the potential for dike breaching.
