Both one-layer and two-layer models were used. Our results indicate that no visible difference betweeen one-layer and two-layer model is found. Furthermore, to understand the nonlinear effect, the reflection coefficients due to periodic seabed are discussed for

Japan and the United States have been exploiting the DOW for utilization in water, pharmaceutical, cosmetic, and fishery industries for many years. Since 2000, Taiwan has started the preliminary planning for the exploitation

A series of large-scale experiments were conducted in the SUPER TANK of Tainan Hydraulics Laboratory with three plane beaches of slope 0.05, 0.025 and 0.017 (1:20, 1:40 and 1:60). Solitary waves of which relative wave heights, H/h0, ranged from 0.03 to 0.31 were generated by two types of wave-board displacement trajectory: the ramp-trajectory and the solitary-wave trajectory proposed by Goring (1979). Experimental results show that under the same relative wave height, the waveforms produced by the two generation procedures becomes noticeably different as the waves propagate prior to the breaking point. Meanwhile, under the same relative wave height, the larger the constant water depth is, the larger the dimensionless run-up heights would be. Scale effects associated with the breaking process are discussed.

The explicit parametric solution gives the trajectory of a water particle and the wave kinematics for Lagrangian points above the mean water level, and in a water column. The water particle orbits and mass transport velocity as functions of the surface tension are obtained. Some

Reducing such conflict of stakeholders has become an important issue during the initial stage of planning Marine Protected Areas (MPAs). When it comes to promoting MPAs, cognitive differences and stakeholder conflict are the two main challenges Taiwan faces. This study collects data from in-depth interviews and
