| Summary: | Equations and tables for estimating Fuess evaporation from climatological data were developed. Ten years of average records from 22 stations in Venezuela were analyzed in order to develop the equations.
Mathematical regression analysis, and plotting and computer programs were used to work out the equations. The form of the final expression for estimating Fuess evaporation is as follows:Ev = K CRCTCWCHCDTCSCM Pan evaporation was computed using the Christiansen, Mathison, Blaney-Criddle, Hargreaves, Penman, and Kohler formulas. The computed pan evaporation from these formulas, measured Fuess evaporation, and computed Fuess evaporation were compared. The equation best suited for estimating Fuess evaporation in Venezuela was selected by statistical analysis. Coefficients were determined for the new Fuess evaporation formula. An example showing ease of application of the equation is given. |
