Wüthrich, D. (author), Teng, Djimin (author), Ke, Q. (author), Diaz, Andres (author), Bortolotti, A. (author), Iuorio, Luca (author), Hooimeijer, F.L. (author)In a world influenced by climate change and consequently sea-level rise, extreme floods are expected to become more frequent in the future, representing a serious threat for riverine and coastal settlements. Therefore, flood protection is a large component of climate adaptation and should be closely related to other measures of climate...conference paper 2022

Tran, N.B. (author), Van Der Kwast, Johannes (author), Mul, Marloes (author), Seyoum, S.D. (author), Uijlenhoet, R. (author), Jewitt, G.P.W. (author)Evapotranspiration (ET), a key variable in both water and energy cycles. It is very challenging to measure or estimate in large regions. Among many approaches to estimate ET indirectly (e.g. through hydrological modelling), models that are based on satellite remote sensing data (RS) are increasingly being used. However, the RS-based models...conference paper 2022

Kroon, M.E.N. (author), Rutten, M.M. (author), Stive, M.J.F. (author), Wunna, S. (author)Coastal squeeze is the reduction in the space of coastal habitats to operate (Phan et al, 2014) and an important cause for coastline retreat, increase in flood risk, salinity intrusion etc. Land use changes, such as deforestation and urbanization, reduce the space of natural habitats, such as mangrove forests, and cause deterioration of these...conference paper 2015

(author)Over the past decades the effect of vegetation (e.g. kelp, mangroves, sea grass) on nearshore coastal processes has received more and more attention. In recent years several numerical wave models have been extended to include this effect. In the current study, the numerical storm impact model XBeach was extended with formulations found in...conference paper 2015

(author)Measurements of nearshore currents can be performed using a range of existing measurement techniques. Although every technique has its specific benefits, capturing strong spatial gradients in a flow field with sufficiently high spatial resolution often proves to be difficult due to high costs or practical difficulties associated with these...conference paper 2015

(author)Deltas are generally recognized as vulnerable to climate change and therefore a salient topic in adaptation science. Deltas are also highly dynamic systems viewed from physical (erosion, sedimentation, subsidence), social (demographic), economic (trade), infrastructures (transport, energy, metropolization) and cultural (multiethnic) perspectives...conference paper 2015

Orru, C. (author), Chavarrias Borras, V. (author), Ferrara, V. (author), Stecca, G. (author), Blom, A. (author)A flume experiment was conducted to examine the evolution of a sand-gravel reach under a lack of sediment supply. A bed composed of a bimodal sediment mixture was installed with a uniform slope and an gradual fining pattern. At the upstream end of the flume the initial bed consisted of 100% gravel, which decreased stepwise (10% steps) in...conference paper 2015

As a result of the intensification of extreme weather conditions and human activities in this area (e.g. land reclamation, river damming, and coastal structures), coastal safety as well as economic and ecological values...conference paper 2015

Van Steeg, P. (author), Labruijere, A. (author), Mom, R. (author)The stability of grass covered slopes on primary flood defences under wave attack is an important aspect with respect to the strength of the entire dike. In a grass slope many transitions to objects (poles, stairs, fences, buildings et cetera) or other revetments (concrete, asphalt, placed block revetment) can be present. This can potentially...report 2015

(author)The Sand Motor is a mega-nourishment characterized by a very large sand volume of around 20 million m3 placed along the Dutch coast. The Sand Motor is a pilot project to evaluate the performance of an alternative nourishment strategy with respect to different functions of the coastal system. Within the scope of the coastal functions, the hook...conference paper 2015

This analysis is normally used by decision-makers in biodiversity conservation, species monitoring and environmental planning, among others. Habitat suitability modelling is a major component of the...conference paper 2015

van Damme, M. (author), Visser, P.J.

Singh, U. (author), Crosato, A. (author), Giri, S. (author), Hicks, M. (author), Mynett, A. (author)Recent studies have shown that the river bed topography is very sensitive to the composition of bed sediment. So, human interventions and natural processes leading to changes in sediment size grading might result in morphological adjustments of river reaches. This study deals with the effects of changing sediment size grading on the braiding...conference paper 2013

Stecca, G. (author), Blom, A. (author)Modelling the morphodynamic evolution of rivers due to flow-driven sediment transport requires the adoption of a flow model, such as the shallow water equations, and a conservation equation for sediment mass (the Exner equation).
