Meiofauna communities in exposed sandy beaches on the Galician coast (NW Spain), six months after the Prestige oil spill: the role of polycyclic aromatic hydrocarbons (PAHs)

open access: yesScientia Marina, 2010
The effect of polycyclic aromatic hydrocarbons (PAHs) on Galician sandy beach ecosystems, six months after the Prestige oil spill, was evaluated using the meiobenthos at a higher taxon level as an indicator. Meiobenthos community structure, environmental

Low-cost mapping of coastal geomorphology by remote sensing in Angels Cove, Arraial do Cabo, Brazil

open access: yesRevista Brasileira de Geomorfologia, 2023
Bathymetry is a crucial information for understanding coastal geomorphological processes. This study aims to evaluate the applicability of Satellite-Derived Bathymetry (SDB) as a low-cost alternative for coastal geomorphological mapping in Angels Cove ...

Fish pass design - criteria for the design and approval of fish passes and other structures to facilitate the passage of migratory fish in rivers [PDF]

open access: yes, 1984
Many of British rivers hold stocks of salmon (Salmo salar L.) and sea trout (Salmo trutta L.) and during most of the year some of the adult fish migrate upstream to the head waters where, with the advent of winter, they will eventually spawn.

Morphological changes, beach inundation and overwash caused by an extreme storm on a low-lying embayed beach bounded by a dune system (NW Mediterranean) [PDF]

open access: yes, 2016
The geomorphological evolution of a low-lying, micro-tidal sandy beach in the western Mediterranean, Pals beach, was characterized using airborne Light Detection and Ranging (LiDAR) data. Data were collected in prior to and six months after the impact of

A hybrid Cartesian loop and envelope modulated PA linear transmitter architecture [PDF]

open access: yes, 2003
A high efficiency and linearity PA solution is presented based on hybrid linearisation schemes that employ complementary techniques to overcome the weakness (or constraints) of either method on its own. In particular, the high linearity of Cartesian loop

Tsunami generation by paddle motion and its interaction with a beach: Lagrangian modelling and experiment [PDF]

open access: yes, 2013
A 2D Lagrangian numerical wave model is presented and validated against a set of physical wave-flume experiments on interaction of tsunami waves with a sloping beach. An iterative methodology is proposed and applied for experimental generation of tsunami-
