Frijns, R.S.J. (author), Tuin, H.G. (author), Voortman, H.G. (author), Bricker, J.D. (author)The nature of the Meuse River is more than any other major river in the Netherlands formed by the presence of weirs. These were constructed almost one century ago to enable transport of coal; nowadays, the boundary conditions have changed and will continue to change in the future. The weirs reach the end of their lifetime around 2030; during...conference paper 2020

Jonkman, Sebastiaan N. (author), Voortman, H.G. (author), Klerk, W.J. (author), van Vuren, S. (author)This article highlights recent developments in flood risk management in the Netherlands and presents approaches for reliability analysis and asset management for flood defences and hydraulic infrastructure. The functioning of this infrastructure is of great importance for the country as large parts of it are prone to flooding. Based on a...journal article 2018

Tsimopoulou, V. (author), Kanning, W. (author), Voortman, H.G. (author), Verhagen, H.J. (author)One of the failure mechanisms of a rubble mound breakwater is the failure of its armour layer. In order to determine the stability of an armour layer, the design load has to be defined, which is in fact the wave that attacks the structure. Being a highly stochastic phenomenon, the wave action is not easily defined, while there is always some...conference paper 2011

Voortman, H.G. (author)In Europe the interest in and the importance of vertical breakwaters is growing. A central point is the optimal geometry, e.g. the width and height of the breakwater caisson chosen such that the total costs over the lifetime of the structure are minimized. Probabilistic design tools provide several methods to determine the probability of failure...master thesis 1997
