Effect of Aquifer Management on Some Soil Properties (Case Study: Meymand Station, Kerman Province)

In addition of precipitation deficiency, the rainfall with high intensity and short duration are the characteristics of arid and semiarid regions. This situation caused huge floods. These floods carries a lot of fine sediments that were silted on land and could change the soil properties. In addition of precipitation deficiency, the rainfall with high intensity and short duration are the characteristics of arid and semiarid regions. This situation caused huge floods. These floods carries a lot of fine sediments that were silted on land and could change the soil properties. In this study, the effect of flood spreading on soil was investigated at Flood Spreading Station after 15 years of its construction. Meymand Floodwater spreading Station is located 210 km from Kerman and has 23 broadcast channels. According to the number of floodwater spreading channels, sampling for soil experiments was carried out from three parts of the flood spreading area (first, middle and end of the flood spreading area), one channel and each channel of three samples were randomly taken from 0 to 30 cm depth. Analysis and comparison of the meanings were done using Duncan test. Statistical analysis of the data showed a significant increase in the percentage of clay, sand, silt, electrical conductivity, saturation percent, total nitrogen, phosphorus and potassium, and a significant decrease in the percentage of sand and saturation percent. There was no significant difference in pH in floodwater spreading and control area.There was no significant difference in pH in floodwater spreading and control area.There was no significant difference in pH in floodwater spreading and control area.
