Fiorillo, Diana (author), Kapelan, Z. (author), Xenochristou, Maria (author), De Paola, Francesco (author), Giugni, Maurizio (author)Assessing the impact of climate change on water demand is a challenging task. This paper proposes a novel methodology that quantifies this impact by establishing a link between water demand and weather based on climate change scenarios, via Coupled General Circulation Models.

Oviedo-Ocaña, E. R. (author), Dominguez, I. C. (author), Celis, J. (author), Blanco, L. C. (author), Cotes, I. (author), Ward, S. (author), Kapelan, Z. (author)Urban areas are facing challenges for the provision of public services, with water scarcity arising as one of the main problems. A twin track approach of supply and demand management is essential, and water-loss management contributes to reducing water demand. However, small municipalities from developing countries have technical, information...journal article 2020

(author), Blokker, E.J.M. (author)Water temperature is often monitored at water sources and treatment works; however, there is limited monitoring of the water temperature in the drinking water distribution system (DWDS), despite a known impact on physical, chemical and microbial reactions which impact water quality. A key parameter influencing drinking water temperature is...review 2020

Montes, Carlos (author), Berardi, Luigi (author), Kapelan, Z. (author), Saldarriaga, Juan (author)Sediment transport in sewer systems is an important issue of interest to engineering practice. Several models have been developed in the past to predict a threshold velocity or shear stress resulting in self-cleansing flow conditions in a sewer pipe. These models, however, could still be improved. This paper develops three new self-cleansing...journal article 2020

Petersson, Louise (author), ten Veldhuis, Marie-claire (author), Verhoeven, Govert (author), Kapelan, Z. (author), Maholi, Innocent (author), Winsemius, H.C. (author)In this paper we demonstrate a framework for urban flood modeling with community mapped data, particularly suited for flood risk management in data-scarce environments. The framework comprises three principal stages: data acquisition with survey design and quality assurance, model development and model implementation for flood prediction. We...journal article 2020

Xenochristou, Maria (author), Kapelan, Z. (author)Water demand forecasting is an essential task for water utilities, with increasing importance due to future societal and environmental changes. This paper suggests a new methodology for water demand forecasting, based on model stacking and bias correction that predicts daily demands for groups of ~120 properties. This methodology is compared...journal article 2020

Montes, Carlos (author), Vanegas, Sergio (author), Kapelan, Z. (author), Berardi, Luigi (author), Saldarriaga, Juan (author)Multiple models from the literature and experimental datasets have been developed and collected to predict sediment transport in sewers. However, all these models were developed for smaller sewer pipes, i.e. using experimental data collected on pipes with diameters smaller than 500 mm. To address this issue, new experimental data were...journal article 2020

Alves, Alida (author), Vojinovic, Zoran (author), Kapelan, Z. (author), Sanchez, Arlex (author), Gersonius, Berry (author)Climate change is presenting one of the main challenges to our planet. In parallel, all regions of the world are projected to urbanise further. Consequently, sustainable development challenges will be increasingly concentrated in cities. A resulting impact is the increment of expected urban flood risk in many areas around the globe....journal article 2020

Sitzenfrei, Robert (author), Wang, Qi (author), Kapelan, Z. (author), Savić, Dragan (author)The optimization of water networks supports the decision-making process by identifying the optimal trade-off between costs and performance (e.g., resilience and leakage). A major challenge in the domain of water distribution systems (WDSs) is the network (re)design. While the complex nature of WDS has already been explored with complex...journal article 2020
