홈페이지논문 초록 (Abstract)
A new technique of predicting a one-dimensional wave transformation due to bottom variation was developed by using analytical andnumerical approaches. The coefficients of the governing equation, the mild sl ope equation, were approximated as polynomialforms using the least squ ares method. The power series technique was applied to solve the second-order ordinary differential equation originally conv erted from the mild slope equation. Because the approximation was carr ied out after setting the coefficient of the highest-order term of the equation to unity, there was no singular point. This solution becam e, consequently, applicable to arbitrarily varying topography . Comparison of results from this study with the numerical solutions ca lculated by the finite element method showed good agreement for variou s cases.
