Impact of Flood Spreading on Infiltration Rate and Soil Properties in an Arid Environment

摘要: Flood spreading (FS) is one of the suitable methods for flood management and water harvesting that increases groundwater recharge, makes soil more fertile nutrients in soil. It also a method reusing sediment, which usually wasted. The purpose this paper to investigate impact on physical chemical properties (soil texture, infiltration rate, pH, EC, Na, P, K, Ca, Mg, Cl, HCO3, SO4). examined change projection area (FSP). physico-chemical rate were measured different depths at both control area. For 20 cm top soil, amount clay increased after implementation especially first second dikes. Increasing was accompanied by decreasing sand percentage. mean differences clay, between FSP statistically significant (P < 0.01). A difference not observed 20–30 depth. Soil Cl SO4 layers did show any FSP. EC 0–20 depth showed 0.05) but no found deeper 0.05). Na Ca remarkably 0 10 whereas Comparison rates dikes shows there are medians dike 1 with 2, 3, 4 5, 5. Our results operation can be influenced under operation. This study allowed us mechanisms regulate throughout seasonally flooded
