The importance of dew in watershed-management research

Abstract

Many studies, using various methods, have been made of dew deposition to determine its importance as a source of moisture. For example, Duvdevani (1947) used an optical method in which dew collected on a wooden block was compared with a set of standardized photographs of dew. Potvin (1949) exposed diamond-shaped glass plates at 45º to ground level, so that condensed dew ran into a graduate. Lloyd (1961) studied amount and duration of dew by using polystyrene blocks mounted on a balance linked to a 7-day continuous recorder. Craddock (1951) devised a sub-groundlevel balance and recorder to give continuous records of dewfall on a soil mass or a plant surface at groundlevel; and the Craddock recorder was later - in 1954 - improved upon by Jennings and Monteith.
