Irrigation with Effluent Water Effects of Rainfall Energy on Soil Infiltration

摘要: Seal formation at soil surfaces is significantly affected by raindrop kinetic energy (KE). We hypothesized that the deterioration in seal permeability of soils irrigated with effluents, relative to fresh water (FW), KE. The effects four droplet KE levels (3.6, 8.0, 12.4, and 15.9 kJ m 3 ) on infiltration parameters Israeli smectitic had been FW or were studied a drip-type rain simulator. At lowest (3.6 3), final rate (IR) values for FW-irrigated samples range 9 14 mm h -1 higher than corresponding effluent-irrigated samples, suggesting seals not fully developed this low irrigation type played major role determining permeability. high (15.9 ), differences between IRs given small (<1.1 KE, effect drop impact overshadowed quality IR. Rate was faster ones, regardless sensitivity all use effluents greatest 8 -3 . both lower levels, IR, FW, less severe.
