| Abstract | ||
| Floodwater spreading stations have been established with different goals. that enhance our understanding of some unknowns and suitable programming for reaching them, can present clear resplendence for future. For these purposes, this study was done to evaluate of some of physical-chemical characteristics change of topsoil in Zanjan floodwater spreading station. A plot in 100×80 m in control site and 3 plots in 500×80 m in spreading site were selected. The infiltration of topsoil was measured by double ring method. The pH, EC, TNV%, P, K, O.C and soil texture in depth of 30 cm was also measured. The results showed that infiltration rate decreased on spreading site, so, its difference with control site was statistically significant at the 1% level. Increase O.C was observed in spreading site compared with the control site. The amount of O.C and silt decreased significantly from up to down of spreading site. Also, within each plot of spreading area the values of infiltration, silt and O.C increased along the slop up to down (from spreading channel to next channel embankment). | ||
