Flood risk reduction by parallel flood defences – Case-study of a coastal multifunctional flood protection zone

Marijnissen, Richard J.C. (author), Kok, M. (author), Kroeze, Carolien (author), van Loon-Steensma, J.M. (author)

In this paper the safety of a double-dike system (or twin dikes) is assessed. Such a system consist of two parallel lines of flood defences. During storms the combined strength of the parallel flood defences must prevent flooding of the hinterland. A culvert can be implemented for the tidal exchange of sea water to enable new land-uses in the...

How natural processes contribute to flood protection: A sustainable adaptation scheme for a wide green dike

Marijnissen, Richard (author), Esselink, Peter (author), Kok, M. (author), Kroeze, Carolien (author), van Loon-Steensma, J.M. (author)

Effective adaptation to sea-level rise is critical for future flood protection. Nature-based solutions including salt marshes have been proposed to naturally enhance coastal infrastructure. A gently sloping grass-covered dike (i.e. Wide Green Dike) can be strengthened with clay accumulating locally in the salt marsh. This study explores the...

The sensitivity of a dike-marsh system to sea-level rise-a model-based exploration

Marijnissen, Richard (author), Kok, M. (author), Kroeze, Carolien (author), van Loon-Steensma, J.M. (author)

Integrating natural components in flood defence infrastructure can add resilience to sea-level rise. Natural foreshores can keep pace with sea-level rise by accumulating sediment and attenuate waves before reaching the adjacent flood defences. In this study we address how natural foreshores affect the future need for dike heightening. A...

Re-evaluating safety risks of multifunctional dikes with a probabilistic risk framework

Marijnissen, R.J.C. (author), Kok, M. (author), Kroeze, Carolien (author), van Loon-Steensma, J.M. (author)

It is not uncommon for a flood defence to be combined with other societal uses as a multifunctional flood defence, from housing in urban areas to nature conservation in rural areas. The assessment of the safety of multifunctional flood defences is often done using conservative estimates. This study synthesizes new probabilistic approaches to...

Marsh Recession and Erosion study of the Fraser Delta, B.C., Canada from Historic Satellite Imagery

Marijnissen, R.J.C. (author), Aarninkhof, S.G.J. (author)

The goal of the study is to map the changes of marsh extent and topography on both Sturgeon Bank and Westham Island between 1980 and now. The study will look for a correlation between the recession and the possible loss of sediment from the banks. If a sediment deficit is a (major) contributor of marsh recession within the...

Full-vector behavior of the geomagnetic field during a mid-Miocene reversal in Gran Canaria: An absolute intensity study

Marijnissen, K.A. (author)

The dynamo of the solid inner core and liquid outer core gives rise to the Earth’s magnetic field, a field that changes in direction and intensity and can be reversed. This process of geomagnetic reversals is still poorly understood, because only a few sections have been recorded in high resolution, which are crucial to get a better...

Reverse movement and coalescence of water microdroplets in electrohydrodynamic atomization

Agostinho, L.L.F. (author), Fuchs, E.C. (author), Metz, S.J. (author), Yurteri, C.U. (author), Marijnissen, J.C.M. (author)

When a high voltage is applied to a liquid pumped through a needle, charged microdroplets can be formed, which are carried along the electric field lines. This phenomenon is called electrohydrodynamic atomization (EHDA), or simply electrospray. In this work we show that in the case of water, droplets may reverse their paths flying back toward...
