Field measurements of salinity from 1978 to 1984 are used to investigate the horizontal structure of the Pearl River buoyant plume during high river discharge. According to the characteristics of horizontal salinity distribution in summer, buoyant plumes are classified into four types - offshore bugle spreading (Typel), west alongshore spreading (TypeII), East offshore spreading (Type III), western and eastern alongshore spreading (Type IV). It is found that the plume shapes vary with time, presenting obvious monthly and annual variations and TypeIIalways occur in June, while in July the plume type has very high probability belong to Type III which controlled by river discharge and local wind.

Journal of Coastal Research, SI 50 (Proceedings of the 9th International Coastal Symposium), 1116 – 1120. Gold Coast, Australia, ISSN 0749.0208 This work focusses on the Bragantinian Coastal Plain, which is located in the northeastern littoral of Para State, presenting an approximately 15 km waterfront. This area is situated in a macrotidal zone strongly affected by natural processes and human activities. The environmental and social aspects of five beaches in the Bragantinian littoral are described taking into account the several natural and human impacts that these beaches have been suffering along the last years. The methodology adopted in this study was based on interviews with inhabitants, direct observations and the monitoring of physical and human components. The obtained results showed that these beaches present several erosive problems, lack of adequate services and infrastructure, land use occupation disorder and lack of governmental incentive to support the sustainable development in the region. In addition, this coastal zone is one of the most frequented areas of the state, and it is considered of good quality by beach users, who pointed out its natural beauty, tranquility and fish abundance. On the other hand, the natural erosive process, intensified by the disordered occupation, is responsible for the destruction of their natural ecosystems and buildings located along the waterfront, mainly during the equinoctial spring tides. Due to importance that the Amazon littoral represents to the world, an urgent action plan is necessary to minimise the social and environmental problems observed in Braganca beaches, promoting a sustainable development of local natural resources.

Journal of Coastal Research, SI 50 (Proceedings of the 9th International Coastal Symposium), 668 – 672. Gold Coast, Australia, ISSN 0749.0208 Seagrass beds (Zostera muelleri) form extensive (> 10 Ha) intertidal beds in New Zealand estuaries potentially altering particle and nutrient fluxes to sediments. The effects of seagrass (blade length 5-8 cm, shoot density ~60/0.01m 2 ) on boundary layer dynamics were investigated at a site exposed to both tidal currents (~20 cm/s) and small wind waves (significant height 2-10 cm) over four days providing a variety of wave-current combinations. Flow characteristics were determined using two ADVs: one fixed at 15 cm above the bed and the other at varying heights within and above the canopy. The vertical variation of currents in and at the edge of the patch and on bare sediment during different tidal stages was measured. The inertial dissipation method was used to characterise changes to dissipation rate caused by varying bed character and hydrodynamic conditions. Results show that Z. muelleri altered the shape of the current profile by extending the boundary layer upward. The presence of waves caused substantial differences within the patch, appearing to increase the bed roughness. Dissipation rates outside the patch increased with proximity to the bed, whereas within the patch, they increased with distance from the bed. Dissipation rates were also observed to be greater on the incoming tide, even when differences in mean current speeds between flood and ebb tide were accounted for. Although the sudden transition at the edges of the Z. muelleri canopy caused more variable boundary profiles, the shape of the current profiles at the edge of the patch were clearly different on the ebb and the flood tides.
