中文摘要 | 本文旨在以非達西理論建立一適用於抽水井附近的非達西標準曲線,藉由合併抽 水井周圍存在之非達西流與遠離井之達西流的概念,可得到完全貫穿井之不平衡公式,並將 其基本微分方程的解析解以標準曲線之圖解法來表示。最後,將以臺灣中部彰濱地區之抽水 試驗應用於非達西標準曲線,從而決定出含水層參數,再以此估測含水層之洩降量,並與達 西標準曲線所求得之結果相互比較。 |
英文摘要 | The purpose of this paper is to establish the type curve for Non-Darcy flow and is useful in determining either the aquifer parameters form the time of drawdown observations or in predicting the drawdown variation in a confined aquifer, that is revision for the residual of the Darcy type curve. First, in accord with the Non-Darcy theory former time it proposed two approaches, namely, the polynomial and the exponential forms, which deduced the formulas of groundwater flows to a well. Nonequilibrium analyses are presented for fully pentrating well by incorporating the concept of the existence of a Non-Darcy flow regime around the pumping well and a Darcian flow regime away from the well. The analytical solution for its primary differential equation is presented in the form of type curves. Finally, the application of the Non-Darcy methodology has been performed for Chang-Hwa Coast to decide that the aquifer parameter, then the estimations of aquifer's drawdowns are done. These results are also compared with those of the Darcy type-curve and the field test data. |
