Evaluation and Determination of the Coefficients of Infiltration Models in Marvdasht Region, Fars Province
Infiltration process plays an important role in water cycle of the nature. Conducting field experiments is necessary to determine the coefficients of infiltration equations due to the dependence of these coefficients to the soil type, soil surface conditions and the amount of initial soil moisture content. This study has been carried out in a field located in Islamic Azad University, Marvdasht ...

متن کاملIntrinsic Sorptivity and Water Infiltration into Dry Soil at Different Degrees of Saturation
The sorptivity S quantifies the effect of capillarity on liquid movement in a porous material. For liquid infiltration into an initially dry material, S is a parameter that is contingent on both liquid and material properties as well as the maximum liquid content behind the infiltrating front, θm. In prior work, Culligan et al. (2005) used scaling analyses to derive a dimensionless, intrinsic s...
متن کاملEffect of Grazing Intensity on Soil Density of Inchehbroon Rangelands (Golestan province, Iran)
Infiltration rate of water into the soil depends on the factors such as rock and litter cover, canopy cover, rainfall intensity, coarse material, land slope, soil texture and amount of initial soil moisture. The most important factors that are effective in the water infiltration rate of rangelands are livestock trampling and vegetation reduction due to the overgrazing. In present study, through...
