Wadi – AL- Hayat area is considered as one of important agriculture areas in south west of Libya, which famous of planting vegetable and fruits, which considered as local market supplier in those productions. Despite of depending on irrigation 100/% on irrigate those crops on the groundwater; however; the irrigation practices was not good.The basic infiltration rate is considered one of the physical properties that effects the irrigation operations important factor where depend on flow rate in sprinkler irrigation and length of frowwr in surface irrigation. If the infiltration rat dose not calculated accurately; that will resulted in runoff or deep percolation. In this paper, double rings methods used to measure the infiltration rate; the date collection was analysis using Kostiakov equations. The result showed that, there was deference between the two sits; with the same irrigations practices in the region
