明渠二維水理模式之應用評估研究

Abstract

本文針對三個水深平均二維有限元素模式，包括RMA2、HIVEL2D及FESWMS，依據理論基礎及數值處理的觀點，提出三模式之研選準則，並利用迴流演算案例及彎道案例之測試，初步評估模式之適用性。最後，將此三模式應用在濁水溪河槽水庫實際案例的模擬。

Three depth-averaged two-dimensional finite-element numerical models, including RMA2, HIVEL2D and FESWMS, have been evaluated in this study. Based on their mathematical formulations, the present study proposes a guideline for model users to select the suitable model.These models have been examined roughly by the simulation of the back-water flow and the bend-flow cases. At last, effect of in river reservoir of Cho-Shui River has been studied through the use of these models.
