Burned chaparral watersheds in southern California have been found to possess a “nonwettable” soil property. This resistance to wetting is believed to be instrumental in producing high surface runoff and erosion rates during storm periods. A laboratory leaching study was conducted to estimate the teachability of a remedial wetting agent treatment in this problem soil. Results from the study showed that the wetting agent treatment persisted after 40 cm of water have passed through the soil samples.
