Empirical Study on Environmental Creation through Artificial Tidal Flats: Oshima Tidal Flats, Shunan City, Yamaguchi Prefecture

Tidal Flats and Muddy Seafloors

The objectives of our studies in FY09 are to collect observations of currents, waves, and bathymetry on tidal flats, and to develop, test, and improve models for tidal-flat processes and for mud-induced dissipation of waves in shallow water. Specific goals relating to tidal flats are to: Investigate the relative importance to the circulation of riverine and tidal flows, and Estimate the bottom ...

Ichnological evidence of Megalosaurid Dinosaurs Crossing Middle Jurassic Tidal Flats

A new dinosaur tracksite in the Vale de Meios quarry (Serra de Aire Formation, Bathonian, Portugal)preserves more than 700 theropod tracks. They are organized in at least 80 unidirectional trackways arranged in a bimodal orientation pattern (W/NW and E/SE). Quantitative and qualitative comparisons reveal that the large tridactyl, elongated and asymmetric tracks resemble the typical Late Jurassi...

Tidal Flats, Muddy Seafloors, Sandy Coasts, and Inlets

Seagrass corridors and tidal state modify how fish use habitats on intertidal coral reef flats

Identifying pathways that animals use to move among ecosystems has become a focus for improving conservation planning. The function of habitat corridors in facilitating animal movement among terrestrial ecosystems is well established. By contrast, the role of habitat corridors for the movement of marine animals is poorly understood. We used underwater video cameras to evaluate the effects of se...

Morphodynamic processes in shallow estuaries: influence of tidal flats and channels on sand transport

Flood/ebb-dominance in net sediment transport of shallow sandy estuaries with tidal flats and channels (typical around the U.K.) is investigated using a 2D model (TELEMAC). The micro-tidal Dyfi Estuary is used as a case study. The along-estuary net sediment transport in the Dyfi has been predicted and characterised as ebbor flood-dominant. The simulations illustrated that shallow waters (inner-...
