97年高雄港域波流場數值模擬及特性研究

Abstract

本計畫將進行兩部分研究，一部份應用高雄港內外海象觀測資料，建立高雄港未來擴建港域之流場分析數值模式，透過96年度與今年度的模擬結果，比較高雄港擴建前後之流場分布及流況改變之差異；另一部份則分析高雄港海域波浪特性，利用樣本機率密度之直方圖與參數化之機率密度函數比對，探討高雄港域最適之波高與週期分布函數，同時透過極值統計分析方式，分析高雄港的波浪設計條件，提供高港局船隻作業及營運維護之參考依據。

Two aims of a 5-year project for the Kaohsiung harbor are procured. One is to set up a numerical model for the hydrodynamics in the Kaohsiung harbor at the present layouts and at the future layouts. The model validity is examined by using new field observations of current patterns at some points inside and outside the harbor. The other is to investigate the wave statistics and extreme analysis for checking design wave conditions. Through wave data collection, some probability density functions (PDF) with two or three parameters are examined to fit the wave-height and wave-period data, respectively. Through statistical test criteria, the best PDF will be determined to describe the wave statistics and be extended to do extreme analysis. The conditions of the design wave will be checked using extreme analysis.
