A Study of Pedotransfer Function Application for Estimating Water Characteristic Curve

, 2014
水分特性曲線為重要的土壤水力性質之一，但是實驗過程卻是非常繁瑣費時。近年來學者們紛紛提出土壤轉換函數（PTFs），利用常見之參數推估水分特性，為往後之研究提供便利之管道。 本研究以採集自台灣各地的22個土壤樣本進行分析，先進行基本土壤物理實驗及水分特性曲線之測定後，隨機選取其中12個土樣為實驗組，再將實驗數據代入van Genuchten Model中擬合出水力性質α與n。爾後利用複迴歸分析中之主成分分析法歸納出實驗組α、n值之迴歸式。並以剩餘10個土樣評估迴歸式之適用性，迴歸公式如下所示： ln⁡(α)

Evaluation of DRAINMOD using saturated hydraulic conductivity estimated by a pedotransfer function model

Direct measurement of soil saturated hydraulic conductivity (Ks) is time-consuming and therefore costly. The ROSETTA pedotransfer function model is able to estimate Ks from soil textural data, bulk density and one or two water retention points.
