Armijos Moya, T.E. (author), van den Dobbelsteen, A.A.J.F. (author), Ottele, M. (author), Bluyssen, P.M. (author)Vegetation systems in combination with biofiltration processes are emerging processes that are expected to have beneficial effects on the improvement of indoor air quality (IAQ). Common indoor plants may provide a valuable strategy to avoid rising levels of indoor air pollution. In an active vegetation system air cleaning rates may be...abstract 2018

Spriggs, A.M.S. (author), Mosselman, E. (author), Schielen, R.M.J. (author), Stancanelli, L.M. (author)Recent policy initiatives in Europe emphasize a movement towards nature-based solutions in flood management; however, a quantitative relationship between specific flood management measures and indicators of ecological health and biodiversity is difficult to establish (Penning et al., 2023). In the Netherlands, several studies have been conducted...abstract 2024

Vuik, V. (author), Jonkman, Sebastiaan N. (author)Salt marshes are a characteristic feature of estuaries and coastal seas. They are found in the upper coastal intertidal zones between land and water, which are regularly flooded by tides and surges. They are covered with salt-tolerant vegetation types, such as herbs and grasses. Sheltering from continuous intense hydrodynamic forcing by waves...abstract 2016

Truong Hong, S. (author), Phan, K.L. (author), Stive, M.J.F. (author), Uijttewaal, W.S.J. (author)The significant defensive role of vegetation in general and mangroves in particular for coastal and estuarine regions has been increasingly recognized. However, understanding the shallow flow field in and around the region of vegetation is still limited. In order to gain more insight, a laboratory experiment of a vegetated compound channel...book chapter 2020

Kamerling, M.W. (author)The paper presents the structural design of a thin barrel vault constructed with Fusée Ceramique infill elements. The load transfer is analyzed and validated. For the structure composed of Fusée Ceramique elements, steel and concrete the stresses are calculated and compared to the stresses given in the codes used from 1950 to the present. The...conference paper 2013

Samir-Saleh, M. (author), Crosato, A. (author)Flume experiments and field observations demonstrating the effects of vegetation on river planforms are reported in literature, but numerical studies of these effects at the river scale are lacking. We investigated the effects of vegetation in a 2D morphodynamic model using submodels for flow resistance and colonisation of newly formed deposits....conference paper 2010

(author)In the Weichselian, the Lower Rhine in the Dutch-German border region has used three courses, dissecting ice-marginal topography inherited from the Saalian. In the Late Weichselian, the three courses functioned simultaneously, with the central one gaining importance and the outer ones abandoning. This study aims to reconstruct the fluvial...conference paper 2012

Suzuki, T. (author), Arikawa, T. (author)In this paper, bulk drag coefficient in rigid dense vegetation is investigated mainly by using a three dimensional numerical simulation model CADMAS-SURF/3D by incorporating Immersed Boundary Method to calculate flow around the vertical cylinder in the Cartesian grid. Large Eddy Simulation is also incorporated as a turbulence model. Firstly,...conference paper 2010

Ali, S. (author), Uijttewaal, W.S.J. (author)At high water stages obstacles in the floodplains of a river contribute to the flow resistance. In particular the elevated vegetated parts are expected to play an important role. The objective of this study is to estimate and parameterize the form drag due to vegetated oblique weir-like obstacles. An experimental study has been carried out in...conference paper 2011

Abd Rahman, M.Z. (author), Gorte, B.G.H. (author), Bucksch, A.K. (author)High density airborne LiDAR, for example FLI-MAP 400 data, has opened an opportunity for individual tree measurement. This paper presents a method for individual tree delineation and undergrowth vegetation removal in forest area. The delineation of individual trees involves two steps namely 1) tree crown delineation based on density of high...conference paper 2009

Cattaneo, N. (author), Di Maria, F. (author), Guzzetti, F. (author), Privitera, A. (author), Righetti, G. (author)In the last eight years the structure of Topographical Database of green areas has been implemented and consolidated: originally born to manage green areas in Milan, it is now used in other cities. Beside the optimizations achieved in data management (i.e. relationship between data and working process, updating procedures, exhaustive Index of...conference paper 2011

Dijkstra, J.T. (author)Seagrasses are a valuable but threatened part of coastal systems. To aid restoration attempts, a model has been made to study the effect of such flexible aquatic vegetation on flow and sediment transport. Because this model needs to be tested against field results, a field experiment was undertaken around an eelgrass meadow in Dinard, France....conference paper 2009

Dijkstra, J.T. (author)Worldwide, aquatic vegetation is important for the physical and ecological condition of coastal areas. Unfortunately, this vegetation (e.g. seagrasses) is also under pressure due to human activities. Protection and restoration are cumbersome, particularly because the complex relations between vegetation and its environment are not yet well...conference paper 2008

Ali, S. (author), Uijttewaal, W.S.J. (author)The Objective of this study is to estimate the form drag due to vegetated weir- like obstacles. Head loss due to submerged vegetated dikes and groins has been modeled by expansion loss form drag model (Energy and momentum balance principles) and it has been compared with experimental data. An experimental study has been carried out on a scaled...conference paper 2009

Dijkstra, J.T. (author), Uittenbogaard, R.E. (author), Stive, M.J.F. (author)In many areas around the world, there is a large interest in the protection and restoration of aquatic vegetation, like eelgrass (Zostera marina), but little is known about the interaction of such vegetation with its environment. To improve this knowledge, a model has been developed that simulates this interaction between highly flexible...conference paper 2006

Pannozzo, N. (author), Leonardi, N. (author), Carnacina, I. (author), Smedley, R. (author)Salt marshes are ecosystems with significant economic and environmental value. They provide numerous services, including nutrient removal, habitat provision and carbon sequestration (Barbier et al., 2011). They are also widely recognised as nature-based solutions for coastal defence due to their ability to buffer storm waves (Leonardi et al.,...conference paper 2021

Dijkstra, J.T. (author)By changing flow patterns and sediment transport, aquatic vegetation can affect the development of estuarine bed topography. Besides, since the sediment transport also determines the amount of light available for photosynthetic growth, the presence of vegetation can also affect its own development. This selfsupporting interaction should be taken...conference paper 2007
