Dijkstra, Y.M. (author), Schuttelaars, H.M. (author), Winterwerp, J.C. (author)Over the last few decades, some estuaries have undergone a transition to a hyperturbid state, characterised by suspended sediment concentrations of several grammes per litre averaged over the water column. To improve our understanding of this transition and of naturally hyperturbid estuaries, we systematically identify the processes allowing...journal article 2018

Pelupessy, Inti (author), Van Werkhoven, Ben (author), Van Elteren, Arjen (author), Viebahn, Jan (author), Candy, A.S. (author), Zwart, Simon Portegies (author), Dijkstra, Henk A. (author)In this paper we present the Oceanographic Multipurpose Software Environment (OMUSE). OMUSE aims to provide a homogeneous environment for existing or newly developed numerical ocean simulation codes, simplifying their use and deployment. In this way, numerical experiments that combine ocean models representing different physics or spanning...journal article 2017

Dijkstra, Y.M. (author), Brouwer, R.L. (author), Schuttelaars, H.M. (author), Schramkowski, G.P. (author)The iFlow modelling framework is a width-averaged model for the systematic analysis of the water motion and sediment transport processes in estuaries and tidal rivers. The distinctive solution method, a mathematical perturbation method, used in the model allows for identification of the effect of individual physical processes on the water...journal article 2017

Gordijn, J.M.W. (author), Dijkstra, W.P. (author), Oosterhout, A.D. (author)All first-year students at Delft University of Technology (TU Delft) are required to take mathematics courses, but their motivation to participate in these courses is generally lower than their motivation for courses that belong to their main field of study. These lower levels of commitment often lead to lower results and weaker understanding of...conference paper 2017

Dijkstra, Y.M. (author), Schuttelaars, H.M. (author), Burchard, Hans (author)We present a systematic analysis of generation mechanisms for exchange flows in partially stratified estuaries using water column (1DV) and width-averaged (2DV) numerical models. We focus on exchange flows generated by eddy viscosity-shear covariance (ESCO). We identify two distinctly different physical mechanisms. The first, tidal ESCO...journal article 2017

De Lucas Pardo, M.A. (author), Dijkstra, Y. (author), van Maren, D.S. (author), Vroom, J (author), van Kessel, T (author), Winterwerp, J.C. (author)The Ems and Loire evolved into hyper-turbid estuaries in the course of the 20th<br/>century. Winterwerp et al. (2013 a, b) argued that narrowing and deepening of these<br/>rivers induced a regime shift towards these hyper-turbid conditions. This regime<br/>shift was presumed to be driven by a positive feed-back between tidal<br/>amplification,...abstract 2017

Sapra, H.D. (author), Godjevac, M. (author), Visser, K. (author), Stapersma, D. (author), Dijkstra, Chris (author)After-treatment technologies are adopted in automobiles and ships to meet strict emission regulations, which increase exhaust back pressure. Furthermore, underwater exhaust systems are employed on board ships to save space, and reduce noise and pollution on working decks. However, water at exhaust outlet creates a flow resistance for the...journal article 2017

(author)Light emission from Si, would allow integration of electronic and optical functionality in the main electronics platform technology, but this has been impossible due to the indirect band gap of Si. In this talk I will discuss 2 different approaches, using unique properties of nanowires, to realize light emission from Si-based compounds.conference paper 2016
