Jia, T. (author), Vallendar, A.J. (author), de Vries, Rinze (author), Kapelan, Z. (author), Taormina, R. (author)Supervised Deep Learning (DL) methods have shown promise in monitoring the floating litter in rivers and urban canals but further advancements are hard to obtain due to the limited availability of relevant labeled data. To address this challenge, researchers often utilize techniques such as transfer learning (TL) and data augmentation (DA)....journal article 2023

Hauser, S.J. (author), Zhu, P. (author)Since the development of the oil industry in the 1860s, petroleum products became increasingly important in economies and shaped the urban form. The impact of oil exploration, exploitation, and transformation led to the creation of districts and cities entirely dedicated to the oil industry. This dynamic relationship between economic activity...journal article 2022

Nefs, Merten (author)Trade infrastructure and logistical activities have long been a source of prosperity as well as nuisance. The gains and pains of logistics, however, are not distributed equally across regions and cities. Important trade hubs such as Rotterdam or Chicago have built strong trade institutions and accumulated urban wealth, hereby making a successful...conference paper 2022

Hut, R. (author), Van de Giesen, N. (author), Houtman, C.J. (author)The relation between pharmaceutical residues along the river Rhine and the demographic characteristics of the upstream population was studied. A sampling campaign was performed in which water samples from the Rhine were taken at 42 locations. Measurements were compared to a two parameter model with regional demographic data as main input. For 12...journal article 2013

(author)Transport van verontreinigingen gebonden aan slib kan een belangrijk deel uitmaken van het totale transport van deze stoffen. Het kan hierbij gaan om grote hoeveelheden die bovendien grensoverschrijdend verplaatst kunnen worden, en grote ecologische effecten teweeg kunnen brengen. Voor een goede inschatting van (ecologische) effecten en van de...report 2008

Charles, W.M. (author)In this thesis, the particle model that takes into account the short term correlation behaviour of pollutants dispersion has been developed. An efficient particle model for sediment transport has been developed. We have modified the existing particle model by adding extra equations for the suspension using a probabilistic concepts (the Poisson...doctoral thesis 2007

Smedes, F. (author), Nummerdor, G.A.N. (author)This study investigated what the best co-factors are for the correction of butyltin contents for differences in sediment composition. For this reason 5 sediment samples were taken at locations with different pollution histories and one at a dumpsite for low-contaminated harbour sludge. Organotin compounds not occurring in the environment were...report 2003

(author)GENERAL Perfluoroalkylated substances (PFAS) is the collective name for a group of fluorinated chemicals, including oligomers and polymers. There are two major production routes for PFAS: Electrochemical fluorination and telomerisation. The products from the first process contain a sulfonyl group (the so-called ECFproducts). The products from...report 2002
