In 1974, the use of glass shields over Bellani plate evaporimeters at Summerland reduced the rate of evaporation by 5.09%. Records from Vancouver indicated a reduction of 6.5–6.9%. On rainy days, not shielding produced serious errors, especially at

Evaporation tests were conducted using black Bellani plate and carborundum block evaporimeters operated at water pressures of 0 to − 64 cm. In both cases, the reduction in recorded evaporation was rapid as the pressure changed from 0 to − 2 cm. A

Correlations were calculated between the peak flow of water per acre delivered to 174 orchards in the Okanagan Valley in 1958 and the irrigation interval used—that is, the interval between the start of one irrigation and the start of the next irrig

Water samples were taken and the stream flow measured at intervals during the summer, 1962, at several locations on a mountain stream and its tributaries which are a source of water for domestic and irrigation purposes for Summerland, B.C. Electrical

The balance sheet method, keeping an account of evapotranspiration (estimated from evaporation as measured by Bellani plates) and rainfall, was used for scheduling irrigations on a practical field basis on five orchards in Summerland, B.C. Four of th

Bare soil was irrigated, covered to prevent evaporation, and sampled periodically to depths of 6 or 7 feet. In 12 tests the total time after irrigating varied from 15 days to 64 days. By charting moisture content against time on log-log paper, straig

Evaporation and evapotranspiration were measured in 1958 and 1959. Bellani plate evaporimeters proved to be just as reliable as Class A pans and more convenient. Evapotranspiration was determined on alfalfa, ladino clover and brome grass growing in l
