中文摘要 | 本文簡單介紹有限元素法在淺水波問題研究上之潛力及其將來可能之發展。本文 並以一維及二維淺水波模式為例分別介紹一維模式在單一河道、匯流河流、分流河系、及天 然河系之應用,並與文獻上其他方法及實驗室模型或現場實際觀測資料作一比較,檢討其精 確度及優劣性。在二維淺水波模式之應用,主要以二維漫地流為例,說明二維淺水波也可以 很成功的應用到更複雜的流域上。 |
英文摘要 | The purpose of this paper is to introduce the major potentials and perspectives of applications of finite element analysis in solving the problems of shallow water wave equations. One-dimensional and two-dimensional shallow water wave equations will both be incorporated into the modeling procedures. For one-dimensional flows, the models will cover the typical single channels, confluence channels system, division channels system, and natural river systems. As far as two-dimensional flows are concerned, the overland flows are investigated. The simulation results are compared with the data obtained by physical modeling and field observation and with the results of other existing literature. The models were found to be very feasible in modeling the complex flow fields of shallow water wave equation problems. |
