Werlen, Vincent (author), Vocke, Richard (author), Brauner, Christian (author), Dransfeld, C.A. (author), Michaud, Véronique (author), Rytka, Christian (author)A new model is proposed for the consolidation of hybrid textiles, in which air entrapment and dissolution are considered. One of the key parameters is tow permeability, which is described by the analytical model of Gebart and validated at very high fibre volume fractions by direct tow permeability measurement. The model also takes into...journal article 2023

Schoenmakers, Max (author)This research is aimed at creating a generic design method for infiltration drywells on sandy soils by acquiring knowledge on the functioning of these wells. Infiltration drywells are vertical infiltration pipes that are installed above the groundwater table and through which stormwater is drained to the subsurface. Infiltration drywells can...master thesis 2022

Gravenberch, Jip (author)Vegetated permeable pavement systems (VPPS) contribute to a more climate-resilient application of urban water management. However, a complete hydrologic evaluation of vegetated permeable pavement systems has not been found in existing literature. This research presents an evaluation of the hydrologic performance of VPPS under Dutch climatic...master thesis 2022

Stegeman, B. (author), Hoffmann, Rob (author), Hopman, Victor (author), Langeveld, J.G. (author), Clemens-Meyer, Franҫois (author)The main application of the mobile geo-electrical measurement is the detection of the presence and determining the location of leakage in sewer systems. To do so, this method relies on the increase in the measured electrical current between an electrode inside and an electrode outside the sewer system. To use this technique for the...journal article 2022

(author), Morreau, Hans (author), Vahrmeijer, Alexander L. (author)BACKGROUND: Pancreatic ductal adenocarcinoma (PDAC) is a highly lethal malignancy in need of effective (immuno)therapeutic treatment strategies. For the optimal application and development of cancer immunotherapies, a comprehensive understanding of local and systemic immune profiles in patients with PDAC is required. Here, our goal was to...journal article 2022

Panasiuk, Oleksandr (author), Hedström, Annelie (author), Langeveld, J.G. (author), Viklander, Maria (author)Infiltration and inflow (I/I) into sanitary sewers causes numerous negative effects on the whole wastewater management system and ultimately, on the receiving waters. Consequently, a number of methods have been developed to analyse the performance of sewer systems with respect to I/I, including: distributed temperature sensing (DTS), closed...journal article 2022

Liu, S. (author), Zhou, Yangxiao (author), Luo, Weijia (author), Wang, Feiran (author), McClain, M.E. (author), Wang, Xu sheng (author)Intensive groundwater exploitation has depleted groundwater storage and led to a series of geo-environmental problems in Beijing Plain, China. Managed Aquifer Recharge (MAR) has been endorsed to mitigate the groundwater storage depletion and achieve groundwater sustainability. A pilot MAR has been tested in the Chaobai River catchment since...journal article 2022

Zhao, Jian (author), Fang, Shangbiao (author), Liu, G. (author), Qi, Weixiao (author), Bai, Yaohui (author), Liu, Huijuan (author), Qu, Jiuhui (author)Biodegradation plays an important role in the removal of organic micropollutants (OMPs) during riverbank filtration (RBF) for drinking water production. The ability of ammonia-oxidizing microorganisms (AOM) to remove OMPs has attracted increasing attention. However, the distribution of AOM in RBF and its role in the degradation of OMPs...journal article 2022

van der Zon, Jelle (author)Tailings are the rock flour which result from the process of mineral extraction at a mine. This waste material is stored in tailings storage facilities, also known as tailings impoundments. These impoundments gradually grow in size during operation as more tailings are produced and stored over time. These structures are however also prone to...master thesis 2021

Xu, Tao (author), Bezuijen, Adam (author), Broere, W. (author)Tunnel-boring machine (TBM) tunnelling through an aquifer will generate excess pore water pressures in the soil around the tunnel face. Accurately predicting the magnitude of the excess pore water pressures is significant because it directly determines the effective face support pressure. In this study, an analytical solution for transient...journal article 2021

Thamban, Anand (author)Infiltration is the uncontrolled flow of air into the building through the envelope, which contributes to a significant amount of heat loss and is estimated to be around 30% of the heating demand. It is therefore essential to estimate the amount of infiltration, to design a suitable heating and cooling system in a building. Empirical relations...master thesis 2020

(author), Collin, Frederique (author)A methodology for identifying and calibrating the material parameters for a coupled hydro-mechanical problem is presented in this paper. For validation purpose, a laboratory-based water infiltration test was numerically simulated using finite element method (FEM). The test was conducted using a self-designed column-type experimental device,...journal article 2020

(author), Abdelrady, Ahmed (author), Peters, Robert W. (author)This paper aims to propose methods to mitigate the risks of flash flood events in arid rural communities with poor infrastructure. A flash flood management case study was conducted at Afouna Village in Egypt, which is characterized by an arid climate and faced a devasting flash flood in 2015. First, the flash flood was modelled and it was...journal article 2020

Mobron, Nadia (author)Bioswales contribute to climate resilience, as they positively impact the urban water infrastructure by improving the water balance and water quality. However, current bioretention design ignores the facts that different designs in different soils and climatic locations produce different performance results.<br/>The effect of polder conditions...master thesis 2019

Dekker, Lennart (author)Gouda deals with land subsidence and groundwater problems. A solution to these challenges is the application of Drainage-Infiltration-Transport (DIT) sewers, on which research is lacking. This thesis provides provides infiltration and drainage capacity values on DIT sewers and helps to understand the governing processes.master thesis 2019

Zaalberg, Piet (author)OpenFOAM allowed the author to simulate a large number of scenarios in which the influences of cross-shore profile shape, cobble porosity, cobble diameter and layer thickness on wave overtopping were examined. Four validation runs and six simulations to map the sensitivity are compared with data from two physical experiments conducted in the...master thesis 2019

Gutiérrez, Juan Pablo (author), van Halem, D. (author), Uijttewaal, W.S.J. (author), del Risco, Efraín (author), Rietveld, L.C. (author)As a consequence of the suspended sediments in river water, cake formation on the streambed and clogging of the aquifer may occur, leading to a decline in the production yield of riverbank filtration systems, particularly in highly turbid river waters. However, naturally occurring flow forces may induce sufficient scouring of the streambed,...journal article 2018

van Damme, M. (author)During infiltration of water in soil, menisci form at the interface of water, grains, and air in the pores, inducing suction due to surface tension. Due to the random distribution of interconnected pores of different sizes, characteristic of porous media, differences in suction and friction inside pores give a diffusing infiltration front. The...journal article 2018
