Abstract

In this research, the effects of water spreading on PHYSICAL AND CHEMICAL CHARACTERISTICS of soil including EC, pH, the percent of sand, silt, clay and soil water saturation were studied. The research was conducted at two close areas: the control and the spreading area. Water spreading was designed, so that the flood water was transported by transition channel to the first diffusion channel and to the next spreading channel. The experiment was performed based on CRD design and the means compared by Duncan's multiple rang test. The samples were randomly gathered from 0-30 centimeter depth from the control area and adjacent water spreading area then PHYSICAL AND CHEMICAL CHARACTERISTICS were analyzed for each sample. The analysis of variance indicated that there is a significant difference between flood spread and control areas at 0.05 and 0.01 levels. Also, mean comparison tests showed that the maximum variation percentage is related to the first diffusion channel. The difference decreases when far from of the first spreading channel. So that at the first flood area all factors showed a significant difference in comparison with controls area. While no significant difference observed between the control area and the fifth flood area.
