A simple model for current speed in tidal channels
Coastal environment ; Denmark ; Hydrodynamics ; Model ; Sea level ; Storm ; Tidal creek ; Tidal current ; Wind
This paper presents a simple non-distributed, PC-based model describing current speed in a tidal channel based on the continuity equation with tide gauge water level as the only time dependent input parameter. This model is tested in a tidal channel
in the Danish Wadden Sea. This type of model can be used to extend and/or complete time series of current speed in a particular tidal channel and to make quick estimates of the current speed, with a minimum of information and CPU consumption.

Resuspension, sediment fluxes, and suspended sediment diffusion coefficients under wave and current forcing in two coastal environments
Atlantic Ocean ; Coastal dynamics ; Coastal environment ; Coastal sedimentation ; Denmark ; Grain size distribution ; North Sea ; Sea current ; Sedimentology ; Turbulence ; Wave ; Wind speed
This study presents results on sedimentation fluxes obtained during deployments of a tripod equipped with sediment traps and instruments for measuring wave and current parameters in each of two environments (Løgstør Broad and Amstrup Bay), dominated
respectively by surface waves and by currents.

Acoustic Doppler current profiler measurments in coastal and estuarine environments : examples from the Tay Estuary, Scotland
Coastal environment ; Current ; Estuary ; Geophysics ; Model ; Scotland ; Suspended load ; United Kingdom ; Water circulation
Acoustic Doppler current profilers (ADCPs) provide a means to measure the components of water current velocities in three dimensions. Using examples of ADCP datasets acquired from the macrotidal Tay Estuary, eastern Scotland, the principles of field
deployment, data acquisition and forms of output are critically summarised. It is shown for the first time in the Tay Estuary, that vertical current velocities are significant and are particularly so in downwelling zones associated with the development

Frontal festures of the Agulhas Current in the Natal Bight
Features of the inshore front of the Agulhas Current between Durban and Richards Bay are investigated by means of historic airborne radiation thermometer data and recent satellite imagery. Small and large frontal eddies are identified

Major characteristics of the air current in 51 Slovak localities. Average velocity and frequency of the wind as well as average frequency of the wind at graduated velocity are worked up. A survey of spatial distribution of the wind velocity

Current trends of coastal research in the Netherlands
Recent Dutch coastal research has also emphasized several other areas of study, including the geologic history of the coastal belt, coastal ecology, and coastal processes. In the latter area, the complex interaction between tidal currents, waves
