L'influence de la radiation, de la conduction de la chaleur, du vent et de l'humidité de l'air sur l'évaporation d'eau par un évaporomètre de Piche, est décrite quantitativement. Une théorie sur l'évaporation d'une surface mouillée soumise à la radiation, élaborée par Penman, a servi de base pour ces considérations. On a obtenu expérimentalement po...

... Of the sunken pans, Colorado pans are perhaps the most widely known. Other smaller evaporimeters (or atmometers), such as the Piche evaporimeter (Piche 1872, de Vries andVenema 1953), are gaining renewed interest as cheaper, reliable replacements to pans for use in, for example, metering ET rc in irrigation scheduling. It was against observations from evaporation pans that Penman (1948) verified estimates of his new meteorological parameterpotential evaporation (E p ). Bridging the gap between such purely physical models and instrumented observations are synthetic estimates that attempt to emulate the performance of instrumentation, such as the PenPan formulation (Linacre 1994, Rotstayn et al. 2006) that adjusts the Penman (1948) equation for E p to better characterize the enhanced radiative and advective dynamics of US Class A evaporation pans. ...
