Chowdhury, M. Kifayath (author), Blom, A. (author), Ylla Arbos, C. (author), Verbeek, Merel C. (author), Schropp, Max H.I. (author), Schielen, R.M.J. (author)Sediment transport capacity and supply of sediment to a river channel increase significantly during peak flow events. Here we study how a river bifurcation system (partitioning water and sediment over its downstream branches) responds to peak flow events. We focus on the Pannerdense Kop bifurcation in the Dutch Rhine River, an engineered system...abstract 2022

Czapiga, Matthew J. (author), Blom, A. (author), Viparelli, Enrica (author)The Waal Branch of the Rhine River has eroded over the last 150 years following channel straightening and narrowing. In 2014–2015 a pilot project replaced existing groynes over an 11 km long reach with three longitudinal training walls (LTWs) to mitigate channel bed erosion, among other purposes. Walls are lower than the river bank and split the...journal article 2022

Garcia (author), Etxebarria, J. G. (author), Ziar, H. (author), Zeman, M. (author), Santbergen, R. (author), Isabella, O. (author)We introduce a novel simulation tool capable of calculating the energy yield of a PV system based on its fundamental material properties and using self-consistent models. Thus, our simulation model can operate without measurements of a PV device. It combines wave and ray optics and a dedicated semiconductor simulation to model the...journal article 2022

The MDLV resource centers on a design model involving seven interactive design skills and a formative assessment model involving five strategies. A team of researchers from seven...conference paper 2022

Ma, H. (author), Blom, H.A.P. (author)This paper focuses on estimating reach probability of a closed unsafe set by a stochastic process. A well-developed approach is to make use of multi-level MC simulation, which consists of encapsulating the unsafe set by a sequence of increasing closed sets and conducting a sequence of MC simulations to estimate the reach probability of each...journal article 2022

He, X. (author), Jiang, C. (author), Li, L. (author), Blom, H.A.P. (author)UAS-based commercial services such as urban parcel delivery are expected to grow in the upcoming years and may lead to a large volume of UAS operations in urban areas. These flights may pose safety risks to persons and property on the ground, which are referred to as third-party risks. Path-planning methods have been developed to generate a...journal article 2022

Czapiga, Matthew J. (author), Blom, A. (author), Viparelli, Enrica (author)Engineering modifications of rivers, e.g., dams or groynes, often induce long-term riverbed erosion, which can be mitigated with sediment nourishments. Here, we consider nourishments to mitigate channel bed erosion induced by channel narrowing, as opposed to the more common application downstream of dams. Our objective is to assess and...journal article 2022

Sun, Yubo (author), Chen, Boyu (author), Zhang, Shizhe (author), Blom, Kees (author), Luković, Mladena (author), Ye, Guang (author)In recent years, the rapid industrialization and urbanization led to the explosive growth of municipal solid waste incineration (MSWI) bottom ashes (BA) production. However, most of them are directly landfilled, which not only brings environmental burden but also results in loss of potential resources. Present researches have proved that MSWI BA...conference paper 2021

Blom, H.A.P. (author), Jiang, C. (author)The unique capabilities of an Unmanned Aircraft System (UAS) creates opportunities for commercial services. The key question is what is an acceptable level of risk posed to third parties on the ground that have no direct benefit from commercial UAS flights. In literature the common view is that an acceptable level of Third Party Risk (TPR) posed...conference paper 2021

Arkesteijn, L. (author), Blom, A. (author), Labeur, R.J. (author)Recent analysis of equilibrium and quasi-equilibrium channel geometry in engineered (fixed-width) rivers has successfully shown that two temporal scales can be distinguished, with quasi-static (long-term) and dynamic (short-term) components. This distinction is based on the fact that channel slope cannot keep pace with short-term fluctuations...journal article 2021

The latter two indicators stem from TPR posed to population by operation of hazardous installations. Literature on TPR of Unmanned Aircraft System (UAS)...journal article 2021
