Khakzad, N. (author), Reniers, G.L.L.M.E. (author)Fires and explosions in chemical plants are still among the major accidents threatening human lives and causing huge asset losses. Although might not completely be eliminated, the risks of such accidents can be reduced by allocating safety measures, applying inherently safer design (ISD) methods, observing land use planning (LUP) regulations,...journal article 2016

Argenti, F. (author), Landucci, G (author), Reniers, G.L.L.M.E. (author)Acts of interference against chemical facilities or chemical clusters might result in severe consequences in case of a successful attack (major explosions, fires, toxic dispersions or environmental contamination). Although process facilities implement multiple safety barriers to control process hazards that may result in major accidents and...journal article 2016

Gough, M.K. (author), Reniers, A.J.H.M. (author), MacMahan, JH (author), Howden, SD (author)The inertial frequency is nearly diurnal at 30°N latitude which transects the northeastern Gulf of Mexico (NeGoM). At this latitude, near-surface inertial oscillations can amplify due to resonance with diurnal wind forcing. Diurnal oscillations have also been attributed to diurnal tidal forcing in this region. Because tidal forcing, wind forcing...journal article 2016

(author)Aquatic vegetation in the coastal zone attenuates wave energy and reduces the risk of coastal hazards, e.g., flooding. Besides the attenuation of sea-swell waves, vegetation may also affect infragravity-band (IG) waves and wave setup. To date, knowledge on the effect of vegetation on IG waves and wave setup is lacking, while they are potentially...journal article 2016

Reniers, G.L.L.M.E. (author)De tijd is gekomen dat antiterrorisme security een volwassen domein wordt in alle chemische bedrijven. De speeltijd is voorbij na de mislukte aanslagen in 2015 op een gasfabriek bij Lyon op 26 juni en een opslagtankfarm bij Marseille op 14 juli. Tot recent waren er de afgelopen decennia geen bekende aanslagen op chemische installaties in het...journal article 2016

(author)Very low frequency (VLF, 0.001–0.005 Hz) waves are important drivers of flooding of low-lying coral reef-islands. In particular, VLF wave resonance is known to drive large wave runup and subsequent overwash.

(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)Larvae of many intertidal species develop offshore and must cross the surf zone to complete their onshore migration to adult habitats. Depending on hydrodynamics, the surf zone may limit this migration, especially on reflective rocky shores. As a logistically tractable analog of a rocky shore environment, we carried out a comprehensive...journal article 2015

Such large nourishments can act as a geometric perturbation, which might cause the tidal current to detach from the coastline. The Sand Motor is a mega-scale beach nourishment in the Netherlands.

(author)Coastal waters are an aerodynamically unique environment that has been little explored from an air-sea interaction point of view. Consequently, most studies must assume that open ocean-derived parameterizations of the air-sea momentum flux are representative of the nearshore wind forcing.
