The influence of installation practices on evaporation from Symon's tank and American Class A-pan evaporimeters
Abstract
Results from Symon's tanks and American Class A-pans proved that the nature of the immediate environment has a pronounced influence on evaporation. Class A-pans above bare soil and crushed stone (both without protective screening) evaporated 6 and 19%, respectively, more than that above grass cover. Bare soil treatments with protective screening evaporated 18% less than those without protection. Symon's tanks surrounded by bare soil and crushed stone evaporated 13 and 12%, respectively, more than tanks surrounded by grass. Symon's tanks in bare soil with protective screens, averaged 16% less evaporation than those without screening. A-pan treatments on different wooden bases above bare soil showed random differences for monthly evaporation, although these differences were not significant on an annual basis.
Annual evaporation for sodium chloride and copper sulphate treatments did not differ significantly from control values.- Publication:
