동수압 모형을 이용한 고립파의 처오름 해석

초록

A three-dimensional hydrodynamic pressure model is newly developed in this study. The velocity components, the free surface elevations and the hydrodynamic pressures are calculated with two steps in the model. In the first step, the momentum equations are solved using the previously calculated hydrodynamic pressure and free surface elevation within a staggered grid system. In the second step, the velocity fields and free surface elevations are obtained. The developed model is applied to propagation and subsequent run-up process of nearshore solitary waves attacking a circular island. The obtained run-up heights are compared with laboratory measurements done by the Coastal Engineering Research Center(CERC), US Army Corps of Engineers. A very reasonable agreement is observed.
