Abstract
Methods of preventing or alleviating clogging of soil pores when spreading water on soil surfaces or injecting water into aquifers for recharge are discussed. Observations of methods such as suction cleaning or scraping to remove clogging materials and restore the infiltration rate in some installed systems are pointed out. Certain past experimental work on the subject is reviewed.Of various filter materials used in infiltrometers at Bakersfield, sand ranging in size from 0.5 to 1.6 mm maintained a higher infiltration rate than ⅛ or ¼ inch pea gravel or the existing aquifer material. Information is given on particle size distribution of both the filter and aquifer materials. Head losses due to filters and within the underlying aquifer are shown.
