The study area is located north of Urmia lake and Tasuj plain. The average height of 1700m and average
rainfall in the area about 363mm. The average annual temperature 10/65°C. Investigations on the surface
penetration of flood deposits are important for the implementation of artificial recharge aquifers. In this study, soil permeability changes from Plain to lake were measured using double cylinders. One of the objectives project is permeability monitoring in the plain geomorphology units. Quaternary deposits Were classified of three classes (Q1, Q2, Q3) with using wells log and geophysical sections showed, Q3 is the youngest deposition. The results showed that the amount of surface cumulative penetration and the rate of penetration of the base was decreasing from the plain to the lake. Plain deposits are mixed clay, sand and gravel. The texture analysis contains 13 percent clay, 18 percent silt and 69 percent sand. The highest rate of penetration of the base with 8.5cm/h corresponds to the north of the plain. The rate of base infiltration from the beginning of the plain to the lake has decreased from 1.3cm/h to about 0.22. The analysis in this unit contains 73 percent of sand in the upper plain and 46 percent on the margin of the lake.
