Comparative Study of Various Formulations of Evaporations from Bare Soil Using In Situ Data

摘要: Abstract Vajious formulations of surface evaporation are tested against in situ data collected over a plot loamy bare ground. Numerical simulations lasting seven days compared with observations near-surface water content and cumulative evaporation. A comparison classical bulk aerodynamic shows similar predictions daytime while significant differences exhibited during the night. The so-called “surface moisture availability method” seems to overestimate nocturnal flux. In context this dataset, threshold methods strongly underestimate whole period observations. sensitivity analysis reveals that (maximum sustainable flux) is highly sensitive upon depth top soil layer.
