Title

INVESTIGATING THE EFFECT OF FLOODWATER SPREADING ON PHYSICO-CHEMICAL SOIL PROPERTIES AT QOOSHEH STATION, SEMNAN PROVINCE

Pages

  39-44

Abstract

 Using of seasonal floodwaters is very important in arid and semi-arid regions. In these areas, surface flow contains a lot of suspended particles that have an effective role in the reduction of infiltration; Therefore, the objective of this research is the investigating the effect of FLOODWATER SPREADING on the QOOSHEH soil project. In this regards, INFILTRATION RATE was measured in 30 points in the FLOODWATER SPREADING area and in 5 points in the area without FLOODWATER SPREADING as witness. The samples were collected in the center of triangles (sites for measuring infiltration) in the field to determine chemical and physical characteristics of soil layers, and the parameters such texture, pH, EC, Na+, Mg++ and Ca++. Based on the results obtained in this research, it is concluded that the sediments are caused variation in the soil texture. In the FLOODWATER SPREADING area, sand percentage shows a decreasing of 2 times, and silt and clay show a decreasing of 2 times compare with the witness. Studying of chemical characteristics of soil also shows that pH and EC had little variation, but Mg++ and Ca++ had an increasing of 2 times and Na+ a decreasing of 2 times compare with the witness. Based on the data collected in the field, after 5 floods, the average of sediment thickness was about 9.0 cm in the back of embankments that caused a decreasing of 9.6 times of INFILTRATION RATE.
