Stelling, G.S. (author)The widespread availability of high-resolution Digital Elevation Models (DEM), has led to the development of subgrid numerical modeling techniques, based on Shallow Water Equations (SWE). Detailed DEM data is clustered as much as possible within a coarse grid cell that is preferably much larger than a raster pixel. This has considerable...journal article 2022

Twisk, Divera (author), Stelling, Agnieska (author), van Gent, P. (author), De Groot, Jolieke (author), Vlakveld, Willem (author)The authors regret that a mistake was made in Table 3 of the article. This table should read: [Table presented] The figures in bold, italic and red differ from the figures in the published article. As a result of these different values, the sixth sentence of the abstract should read: “S-pedelecs were much faster than conventional bicycles,...journal article 2022

Leskens, Johannes G. (author), Kehl, C. (author), Tutenel, T. (author), Kol, T.R. (author), de Haan, G. (author), Stelling, G.S. (author), Eisemann, E. (author)Developing strategies to mitigate or to adapt to the threats of floods is an important topic in the context of climate changes. Many of the world’s cities are endangered due to rising ocean levels and changing precipitation patterns. It is therefore crucial to develop analytical tools that allow us to evaluate the threats of floods and to...journal article 2017

Volp, N.D. (author), van Prooijen, Bram (author), Pietrzak, J.D. (author), Stelling, G.S. (author)Long term morphodynamic simulations are used for predicting the impact of climate change and human interventions in our estuarine and coastal regions. The accuracy of this type of simulations suffers generally from low resolution grids. Eventhough high resolution bathymetry data is increasingly more available thanks to new measurement techniques...abstract 2016

Platzek, F.W. (author), Stelling, G.S. (author), Jankowski, J.A. (author), Pietrzak, J.D. (author)Three-dimensional hydrodynamic z-layer models, which are used for simulating the flow in rivers, estuaries, and oceans, suffer from an inaccurate and often discontinuous bottom shear stress representation, due to the staircase bottom. We analyze the governing equations and clearly show the cause of the inaccuracies. Based on the analysis, we...journal article 2014

Volp, N.D. (author), Van Prooijen, B.C. (author), Stelling, G.S. (author)This study presents a finite volume hydrodynamic model for shallow water flow that computes on a coarse grid, but accounts for high-resolution bathymetry and roughness variations on a subgrid. The detailed information can be incorporated by using the assumption of a uniform flow direction and a uniform friction slope within a part of a coarse...journal article 2013

Bermudez, M. (author), Pietrzak, J.D. (author), Cea, L. (author), Puertas, J. (author), Stelling, G.S. (author), De Boer, G.J. (author)In this paper we explore the role of the river run-off, the tidal regime and the local winds in the dynamics of the Ria de Arousa estuary during the summer period, using for that purpose the numerical model Delft3D. First of all, a simulation under real hydrological and meteorological conditions is conducted in order to validate the ability of...conference paper 2013

Roelvink, D. (author), Stelling, G. (author), Hoonhout, B.M. (author), Risandi, J. (author), Jacobs, W. (author), Merli, D. (author)The formulations of the 2DH process-based, nearshore morphological model XBeach were extended to allow for curvilinear grids using a finite volume approach. The formulations were tested for schematic cases such as a circular island and a field validation study was carried out for the case of storm erosion during a construction phase of the soft...conference paper 2012

Kernkamp, H.W.J. (author), Van Dam, A. (author), Stelling, G.S. (author), De Goede, E.D. (author)In this paper, a shallow-water flow solver is presented, based on the finite-volume method on unstructured grids The method is suitable for flows that occur in rivers, channels, sewer systems (1D), shallow seas, rivers, overland flow (2D), and estuaries, lakes and shelf breaks (3D). We present an outline of the numerical approach and show three...journal article 2011

Kleptsova, O. (author), Stelling, G.S. (author), Pietrzak, J.D. (author)In this paper, we focus on a conservative momentum advection discretisation in the presence of zlayers. While in the 2Dcase conservation ofmomentum is achieved automatically for an Eulerian advection scheme, special attention is required in the multi-layer case. We show here that an artificial vertical structure of the flow can be introduced...journal article 2010

Ham, D.A. (author), Pietrzak, J. (author), Stelling, G.S. (author)A new scheme for the construction on an unstructured grid of the streamlines of the three-dimensional shallow water equations is presented. The qualitative advantages of the scheme, notably closed streamlines and realistic treatment of closed boundaries, are derived and the spatial accuracy is demonstrated. Semi-Lagrangian advection schemes...journal article 2005
