Water Repellency Induced by Organic Matter (OM) in Treated Wastewater (TWW) Infiltration Ponds and Irrigation

摘要：

　　TWW irrigation is being largely applied to soils in semiarid and arid regions around the world that are subjected to a shortage of fresh water (FW) resources.This research dealt with effects of TWW irrigation on water infiltration,retention and distribution in soils.Long term TWW irrigation was found to alter physicochemical properties of soils due to accumulation of OM originating from the applied TWW and may result soil water repellency (SWR).This research dealt with two aspects of the problem:(i) SWR in TWW irrigated soils;and (ii) SWR in infiltration basins (tertiary treatment) of wastewater.Significant SWR was found in these two systems involving utilization of TWW.
