van der Werf, Job (author)REAL-time control (RTC) is a technique used to dynamically control urban drainage systems to utilise the existing infrastructuremore optimally. It can be used to achieve a number of objectives aiming to improve the functioning of the urban drainage system, typically through the reduction of pollution. When heavy rainfall occurs, combined sewer...doctoral thesis 2023

van der Werf, Job (author), Kapelan, Z. (author), Langeveld, J.G. (author)Urban Drainage Systems can cause ecological and public health issues by releasing untreated contaminated water into the environment. Real-time control (RTC), augmented with rainfall nowcast, can effectively reduce these pollution loads. This research aims to identify key dynamics in the nowcast accuracies and relate those to the performance...journal article 2023

van der Werf, Job (author), Kapelan, Z. (author), Langeveld, J.G. (author)Urban areas are constantly developing and thereby affect the local water cycle. Real-time control (RTC) strategies are used to operate urban drainage systems optimally during these transitions. This paper aims to develop a methodology to study the impacts of common gradual changes occurring in the urban environment (densification of the urban...journal article 2023

van der Werf, Job (author), Kapelan, Z. (author), Langeveld, J.G. (author)Model Predictive Control (MPC) of Urban Drainage Systems (UDS) has been established as a cost-effective method to reduce pollution. However, the operation of large UDS (containing over 20 actuators) can only be optimized by oversimplifying the UDS dynamics, potentially leading to a decrease in performance and reduction in users' trust, thus...journal article 2023

Piadeh, Farzad (author), Behzadian, Kourosh (author), Chen, Albert S. (author), Campos, Luiza C. (author), Rizzuto, Joseph P. (author), Kapelan, Z. (author)Urban flooding is a major problem for cities around the world, with significant socio-economic consequences. Conventional real-time flood forecasting models rely on continuous time-series data and often have limited accuracy, especially for longer lead times than 2 hrs. This study proposes a novel event-based decision support algorithm for...journal article 2023

Brevoord, Sophie (author)Urban wastewater systems can impact the urban ecology by untreated wastewater discharges through combined sewer overflow (CSO) events, or by partial treatment of the wastewater at the wastewater treatment plant (WWTP). CSO events can cause oxygen depletion, eutrophication, and the discharge of pathogens. The partial treatment of the wastewater...master thesis 2022

Karami, Mozhgan (author), Behzadian, Kourosh (author), Ardeshir, Abdollah (author), Hosseinzadeh, Azadeh (author), Kapelan, Z. (author)This paper presents a multi-criteria risk-based approach for managing urban flood hazards by using a combination of conventional measures and contemporary Sustainable Drainage Systems (SuDS). A multi-objective optimisation model coupled with a simulation model of UDS in the SWMM software is developed with the three objectives of minimising...journal article 2022

Garzón Díaz, J.A. (author), Kapelan, Z. (author), Langeveld, J.G. (author), Taormina, R. (author)Surrogate models replace computationally expensive simulations of physically-based models to obtain accurate results at a fraction of the time. These surrogate models, also known as metamodels, have been employed for analysis, control, and optimization of water distribution and urban drainage systems. With the advent of machine learning (ML),...review 2022

Huang, Yuan (author), Zhang, Jiangjiang (author), Zheng, Feifei (author), Jia, Yueyi (author), Kapelan, Z. (author), Savić, Dragan (author)Urban drainage models (UDMs) are often used to manage urban flooding. However, these models generally involve many parameters to represent the underlying complex hydrodynamic processes. This results in significant challenges to achieving effective and robust model calibration especially with frequently limited observations, leading to...journal article 2022

van der Werf, Job (author), Kapelan, Z. (author), Langeveld, J.G. (author)To evaluate the performance of Real Time Control (RTC) of urban drainage systems (UDS) a comparison is made with the pre-RTC situation, making the RTC performance dependent on the functioning of the UDS prior to implementation. To standardise things, a generalised baseline is formulated here as the operation with optimal static settings of the...journal article 2021

Vollaers, Vita (author), Nieuwenhuis, E.M. (author), van de Ven, F.H.M. (author), Langeveld, J.G. (author)Despite being widely implemented, sustainable urban drainage systems (SUDS) do not always function flawlessly. While SUDS have been tested extensively and seem to perform well on a laboratory or pilot scale, practitioners’ experience is different: failures in SUDS occur regularly in practice, resulting in malfunctioning systems, water...journal article 2021

Mulder, M.G.J. (author)Additional thesis - Due to an expected increase in rainfall intensity in the future because of climate change for the area of Rotterdam, the amount of storm water runoff will increase as well, resulting in higher stress on the sewer system. But until now we don’t fully understand the behavior of a sewer system. This additional thesis should help...student report 2017

van Daal-Rombouts, P.M.M. (author), Gruber, Günter (author), Langeveld, J.G. (author), Muschalla, Dirk (author), Clemens, F.H.L.R. (author)Real time control (RTC) is generally viewed as a viable method for optimising the performance of urban wastewater systems. A literature review on the performance evaluation of RTC demonstrated a lack of consensus on how to do this. Two main deficiencies were identified: omitting uncertainty analysis and applying limited evaluation periods. A...journal article 2017

(author)Optimisation or real time control (RTC) studies in wastewater systems increasingly require rapid simulations of sewer systems in extensive catchments. To reduce the simulation time calibrated simplified models are applied, with the performance generally based on the goodness of fit of the calibration. In this research the performance of three...journal article 2016

Geerling, H.R. (author)The research focused on the quantitative performance of infiltration swales on an urban catchment scale. A swale in the city of Utrecht was monitored for 5.5 weeks. Groundwater levels, inflow and outflow were measured. The measured data was used for the validation of a swale model in MetaSwap-Modflow developed for this research. An Infoworks...master thesis 2014

Lucke, T. (author), Boogaard, F. (author), Van den Ven, F. (author)Permeable pavements are specifically designed to promote the infiltration of stormwater through the paving surface in order to reduce run-off volumes and to improve water quality by removing sediment and other pollutants. However, research has shown that permeable pavements can become clogged over time and this reduces their infiltration...journal article 2014
