Abstract:	本研究以理論推導,土壤深層的空氣壓縮對入滲通量的減緩。公式的推導主要是根據達西公式,並且多考慮空氣壓力的因子。用沙箱實驗佐證,結果顯示實測值與理論值吻合。實驗結果亦顯示空氣壓縮壓力不是定值,而隨土壤深度而變。 A theory was developed to estimate reduction of infiltration flux because of air compression in deeper soil profile before the wetting front. This theory is based on Darcy's equation with the effect of air pressure. This theory was tested in a sand column, and the experimental result confirms with theory estimation. The experiment shows that air compression is not a constant value but varies with depth.
