Pol, J.C. (author), Kanning, W. (author), van Beek, Vera M. (author), Robbins, Bryant A. (author), Jonkman, Sebastiaan N. (author)Backward erosion piping (BEP) is a form of internal erosion which can lead to failure of levees and dams. Most research focused on the critical head difference at which piping failure occurs. Two aspects have received less attention, namely (1) the temporal evolution of piping and (2) the local hydraulic conditions in the pipe and at the pipe...journal article 2022

Robbins, B. A. (author), van Beek, V. M. (author), Pol, J.C. (author), Griffiths, D. V. (author)Backward erosion piping (BEP) is a type of internal erosion responsible for the failure of many dams and levees. BEP occurs when small, shallow erosion channels progress upstream through foundation sands beneath the structure. As analysis of BEP involves coupling two different sets of flow equations to describe the groundwater flow and...journal article 2022

Pol, J.C. (author), van Klaveren, W. (author), Kanning, W. (author), van Beek, V.M. (author), Robbins, B. (author), Jonkman, Sebastiaan N. (author)Most research on backward erosion piping (BEP) focuses on the critical conditions leading to failure. This paper studies the development of piping over time once the critical conditions are exceeded, which is useful to estimate time to failure. A commonly used small scale rectangular box setup is modified in order to monitor pore pressures and...conference paper 2021

Hammer, T.C. (author), van Beek, C. (author), Koning, J.R.A. (author), Hendrikse, H. (author)With the ongoing development of offshore wind in cold regions where the foundations are exposed to sea ice, there is a strong need for data to validate the numerically predicted dynamic interaction between ice and structure used for design. Full-scale data is non-existent and only a limited number of experimental campaigns in ice tanks have been...conference paper 2021

Andreadis, G. (author), Mastenbroek, Fabian Mastenbroek (author), van Beek, V.S. (author), Iosup, A. (author)Cloud datacenters provide a backbone to our digital society. Inaccurate capacity procurement for cloud datacenters can lead to significant performance degradation, denser targets for failure, and unsustainable energy consumption. Although this activity is core to improving cloud infrastructure, relatively few comprehensive approaches and...journal article 2021

van Beek, Maarten T. (author), Viré, A.C. (author), Andersen, Søren J. (author)Wind farms experience significant efficiency losses due to the aerodynamic interaction between turbines. A possible control technique to minimize these losses is yaw-based wake steering. This paper investigates the potential for improved performance of the Lillgrund wind farm through a detailed calibration of a low-fidelity engineering model...journal article 2021

Rozendaal, M.C. (author), van Beek, E. (author), Haselager, Pim (author), Abbink, D.A. (author), Jonker, C.M. (author)In the context of human-agent interaction, we see the emergence of computational artefacts that display hybridity because they can be experienced as tools and agents. In this paper we propose a tool-agent spectrum as an analytical lens that uses ‘intention’ as a central concept. This spectrum aims to clarify how a computational object can change...conference paper 2020

(author)Our interactions form an intricate 'dance' - a dance requiring a fluent integration of both expressivity (e.g. to approach someone) and sensitivity (e.g. detect if you 'should' approach someone). Work on behaving artefacts has focused mostly on the social, emotional and aesthetic qualities that can be evoked - expressed - through interactions...conference paper 2020

(author)Rainfall-triggered shallow landslides are widespread natural hazards around the world, causing many damages to human lives and property. In this study, we focused on predicting landslides in a large region by coupling a 1 km-resolution hydrological model and a 90 m-resolution slope stability model, where a downscaling method for soil moisture...journal article 2020

Pol, J.C. (author), van Beek, Vera (author), Kanning, W. (author), Jonkman, Sebastiaan N. (author)Backward erosion piping is an important failure mode of dikes and dams. The time required for the backward erosion process to result in dike failure is expected to be an important factor in the safety of dikes. This holds especially in coastal and estuarine areas which are dominated by storm surge, and pipes may not fully develop during a storm....conference paper 2019

van Beek, V.M. (author), Hoffmans, G.J.C.M. (author)The prediction of backward erosion piping is important for safety assessment of dikes in the Netherlands, where subsurface conditions are prone to this erosion mechanism. In the current assessment methodology, the adapted Sellmeijer rule is in use. In combination with the national safety philosophy and uncertainty in input parameters, this model...conference paper 2017

Robbins, B.A. (author), van Beek, V.M. (author)A novel laboratory device is presented, in which the process of backward erosion piping is observed in cylindrical sand samples oriented horizontally. The cylindrical shape of the testing device constrained the location of the erosion path to the top of the sample, thereby allowing pore pressure measurements to be made in both the eroded pipe...conference paper 2017

Vandenboer, K. (author), van Beek, V.M. (author), Bezuijen, A. (author)Backward erosion piping is an important failure mechanism for water-retaining structures, a phenomenon that results in the formation of shallow pipes at the interface of a sandy or silty foundation and a cohesive cover layer. Although the pipe depth reveals a lot of information on the backward erosion process, it has never been measured...conference paper 2017
