Abstract
Three glass columns with a high of 0.8 m and a diameter of 0.055 m used to fill it with a three different soil texture passed through a 2mm sieve with a three replicate, water column with a high of ±3 cm was applied, discharge were received at 0.15m, 0.3m and 0.4m depth increments to study the change of the moisture content length of wetting front percentagevolume discharged related to length of wetting front and the hydraulic head which considered as a function to predict the value of hydraulic conductivity.
The results indicated that the values of the hydraulic conductivity as a function of the hydraulic head content and length of wetting front were Closer compared with that as a function of percentage of volume discharged related to wetting front and moisture content and were height in three soils to that of both properties of variation of water content and percentage of water volume discharged related to length of wetting front.
