Cover Story: A floating bridge across the mouth of the narrow fjord-like waterbody of Hood Canal, Washington impacts water quality parameters and creates a migration barrier for surface-oriented fish species. The bridge floats on concrete pontoons, which span 85% of the width of the canal and extend several meters into the water column. Three-dimensional hydrodynamic models of Hood Canal, validated by an intensive field data collection program, show that the pontoons obstruct the brackish outflow surface layer, causing increased local mixing and up-current pooling/down-current sheltering during ebb and flood tidal exchange. This physical obstruction within the upper water column alters temperature, salinity, and current velocity near the bridge. The cover image shows the Hood Canal Bridge infrastructure within the waterbody and demonstrates the pooling/sheltering effects of the physical barrier. View this paper.

The highly urbanized estuary of San Francisco Bay is an excellent example of a location susceptible to flooding from both coastal and fluvial influences. As part of developing a forecast model that integrates fluvial and oceanic drivers, a case study...

This study addresses the problem of age determination of the southern king crab (Lithodes santolla). Given that recapture is difficult for this species and, thus, age cannot be directly determined with the help of the annual marks on the shell, the v...

13 December 2018

The wave impacts on horizontal and vertical step fronts of stepped revetments is investigated by means of hydraulic model tests conducted with wave spectra in a wave flume. Wave impacts on revetments with relative step heights of 0.3 < Hm0/Sh <...

On Air-Cavity Formation during Water Entry of Flexible Wedges

  • Giangiacomo Minak

12 December 2018

Elastic bodies entering water might experience fluid–structure interaction phenomena introduced by the mutual interaction between structural deformation and fluid motion. Cavity formation, often misleadingly named cavitation, is one of these. T...

Our research focuses on refining the ability to discriminate two petrogenic oil-slick categories: the sea surface expression of naturally-occurring oil seeps and man-made oil spills. For that, a long-term RADARSAT-2 dataset (244 scenes imaged between...

We present a model for the morphodynamics of tidal basin-inlet-delta systems at the centennial time scales. Tidal flow is calculated through a friction dominated model, with a semi-empirical correction to account for the advection of momentum. Transp...

This paper presents the design of a linear quadratic (LQ) optimal controller for a spar-type floating offshore wind turbine (FOWT). The FOWT is exposed to different sea states and constant wind turbulence intensity above rated wind speed. A new LQ co...

Most guidelines on wave overtopping over coastal structures are based on conditions with waves from one direction only. Here, wave basin tests with oblique wave attack are presented where waves from one direction are combined with waves from another...
