Yan, Y. (author), Vreeburg, Wouter (author), Chen, Guangming (author), Schott, D.L. (author)Using bionic surface on the material equipment interface of bulk handling equipment is a promising solution for wear reduction. A bionic surface is a flat surface outfitted with a pattern of convexes that disrupt the natural sliding flow of bulk material. Previous numerical work has shown a significant reduction of wear of bionic surfaces...conference paper 2019

(author)Population growth and climate change place a strain on water resources; hence, there are growing initiatives to reduce household water use. UKWIR (2016) have a stated aim to halve water abstraction by 2050. This will significantly reduce inflow to sewer systems and increase wastewater concentration. This work presents a new stochastic sewer...journal article 2019

Zlatanovic, L. (author), Knezev, A (author), van der Hoek, J.P. (author), Vreeburg, Jan (author)Drinking water and fire safety are strongly bonded to each other. Actual drinking water demand and fire flows are both delivered through the same network, and are both devoted to public health and safety. In The Netherlands, the discussion about fire flows supplied by the drinking water networks has drawn fire fighters and drinking water...journal article 2018

Zlatanovic, L. (author), van der Hoek, J.P. (author), Vreeburg, J.H.G. (author)The drinking water quality changes during the transport through distribution systems. Domestic drinking water systems (DDWSs), which include the plumbing between the water meter and consumer's taps, are the most critical points in which water quality may be affected. In distribution networks, the drinking water temperature and water residence...journal article 2017

Zlatanovic, L. (author), Moerman, A. (author), van der Hoek, J.P. (author), Vreeburg, J.H.G. (author), Blokker, M (author)Domestic drinking water supply systems (DDWSs) are the final step in the delivery of drinking water to consumers. Temperature is one of the rate-controlling parameters for many chemical and microbiological processes and is, therefore, considered as a surrogate parameter for water quality processes. In this study, a mathematical model is...journal article 2017

Testing the robustness of two water distribution system layouts under changing drinking water demandAgudelo-Vera, Claudia (author), Blokker, M (author), Vreeburg, J (author), Vogelaar, H. (author), Hillegers, S (author), van der Hoek, J.P. (author)A drinking water distribution system (DWDS) is a critical and a costly asset with a long lifetime. Drinking water demand is likely to change in the coming decades. Quantifying these changes involves large uncertainties. This paper proposes a stress test on the robustness of existing DWDS under changing drinking water demands. The stress test...journal article 2016

(author)A methodology to determine the robustness of the drinking water distribution system is proposed. The performance of three networks under ten future demand scenarios was tested, using head loss and residence time as indicators. The scenarios consider technological and demographic changes. Daily patterns were simulated with SIMDEUM for each...journal article 2014

Moerman, A. (author), Blokker, M. (author), Vreeburg, J. (author), Van der Hoek, J.P. (author)Domestic water supply systems are the final stage of the transport process to deliver potable water to the customers’ tap. Under the influence of temperature, residence time and pipe materials the drinking water quality can change while the water passes the domestic drinking water system. According to the Dutch Drinking Water Act the drinking...journal article 2014

Bakker, M. (author), Rajewicz, T. (author), Kien, H. (author), Vreeburg, J.H.G. (author), Rietveld, L.C. (author)Conventional automatic production flow control and pump pressure control of water supply systems are robust and simple: production flow is controlled based on the level in the clear water reservoir and pump pressure is controlled on a static set-point. Recently, more advanced computer-based control methods were developed in which production flow...journal article 2014

Bakker, M. (author), Jung, D. (author), Vreeburg, J. (author), Van de Roer, M. (author), Lansey, K. (author), Rierveld, L. (author)Pipe bursts in a drinking water distribution system lead to water losses, interruption of supply, and damage to streets and houses due to the uncontrolled water flow. To minimize the negative consequences of pipe bursts, an early detection is necessary. This paper describes a heuristic burst detection method, which continuously compares...journal article 2014

Bakker, M. (author), Van Duist, H. (author), Van Schagen, K. (author), Vreeburg, J. (author), Rietveld, L. (author)Literature shows that water demand forecasting models which use water demand as single input, are capable of generating a fairly accurate forecast. However, at changing weather conditions the forecasting errors are quite large. In this paper three different forecasting models are studied: an Adaptive Heuristic model, a Transfer/-noise model, and...journal article 2014

Pieterse-Quirijns, I. (author), Blokker, E.J.M. (author), van der Blom, E.C. (author), Vreeburg, J.H.G.

They generally overestimate peak demand values required for the design of an efficient and reliable water system. Recently, a...journal article 2013
