چکیده

Acid deposition is one of the most important environmental issues in East Asia including Japan. The long range transport of acidic species from Asian continent to Japan islands cause large amount of acid deposition especially in winter. These phenomena are strongly affected by the precipitation on the sea, however, it is not easy to get enough information on it. This study aims to develop a simplified probabilistic model to estimate the precipitation on the sea for long term prediction of transportation and deposition of acidic species in East Asia.

Development of a Computer Model for the Prediction of Littoral Sediment Transport Rate

In this paper, longshore sediment transport in littoral zones is investigated. For investigation of sediment transport in the nearshore zone, the effects of waves, currents and topographical conditions of coast are considered. Linear wave theory was used for the investigation of the wave behaviour. Governing equations of littoral current are continuity and momentum ones. For calculating concent...
