First

Evaporation Estimations

Meyer's Formula (1915): EL = KM (ew - ea) ( I + u9/16 )

u9 = monthly mean wind velocity about 9 m above ground

KM = coefficient of 0.36 for large deep waters and 0.50 for small,

shallow waters

The limitations of the formula that at best be expected to give an approximate magnitude of the evaporation.
