Beach Profile Evolution towards Equilibrium from Varying Initial Morphologies

open access: yesJournal of Marine Science and Engineering, 2019
The evolution of different initial beach profiles towards the same final beach configuration is investigated based on large-scale experimental data. The same wave condition was performed three times, each time starting from a different initial profile ...

Constant lift rotor for a heavier than air craft [PDF]

open access: yes, 1979
A rotor blade extended radially from a hub, characterized by an elongated spar and a plurality of axially aligned shells pivotally mounted on the spar is presented.

WAVE PERIOD AND THE SWASH ZONE ENERGY BALANCE

open access: yesCoastal Engineering Proceedings, 1968
The shape sorting of pebbles in the swash zone was studied in an effort to determine the effect of the amount of foreshore infiltration per wave on the swash zone energy balance. Measurements were made of pebbles collected from the swash limit and from the step of selected sandy beaches.

Microfungal diversity in the swash zone interstitial water (SZIW) of three Ligurian urban beaches (NW, Italy)

open access: yesItalian Journal of Mycology, 2017
Microfungal species abundance and specific composition of three urban beaches near Genoa (Liguria, NW Italy) in the swash zone interstitial water (SZIW) were evaluated. These beaches are characterized by a high presence of tourists. The investigation was

Geomorphological control on boulder transport and coastal erosion before, during and after an extreme extra-tropical cyclone [PDF]

open access: yes, 2016
Extreme wave events in coastal zones are principal drivers of geomorphic change. Evidence of boulder entrainment and erosional impact during storms is increasing.

Motion of water and sediment due to non-breaking waves in the swash zone

open access: yesOceanologia, 2012
A long wave run-up theory is applied to the modelling of wave-induced flow velocities, sediment transport rates and bottom changes in a swash zone. First, the properties of the water tongue motion and the resulting lithodynamic response are analysed ...

Relationship between high-frequency sediment-level oscillations in the swash zone and inner surf zone wave characteristics under calm wave conditions

open access: yesOpen Geosciences, 2016
Swash zone topography rapidly responds to the surf zone waves. Understanding how sandy beaches respond to wave action is critical for beach erosion research, and plays a critical role in the design and maintenance of shore protection structures. The main

LANDSAT application of remote sensing to shoreline-form analysis [PDF]

open access: yes
The author has identified the following significant results. LANDSAT imagery of the southern end of Assateague Island, Virginia, was enlarged to 1:80,000 and compared with high altitude (1:130,000) and low altitude (1:24,000) aerial photography in an ...

Shifting sands [PDF]

open access: yes, 2007
The article presents the proposed changes to the New Zealand Draft Curriculum on the Nature of Science. In July 2006, the draft was released to school and the wider educational community for consultation on the national curriculum policy.

Swash zone morphodynamics

open access: yes, 2003
The morphodynamical evolution of four beaches in Europe have been monitored during swash processes, together with the fluctuations of the water table and the recording of the hydrodynamical conditions.
