An analytical model of evaporation efficiency for unsaturated soil surfaces with an arbitrary thickness
Analytical expressions of evaporative efficiency over bare soil (defined as the ratio of actual to potential soil evaporation) have been limited to soil layers with a fixed depth and/or to specific atmospheric conditions. To fill the gap, a new analytical model is developed for arbitrary soil thicknesses and varying boundary layer conditions. The soil evaporative efficiency is written [0.5 − 0....
متن کاملEstimating Evaporation Coefficient during Two-stage Evaporation from Soil Surfaces
Evaporation coefficient (KE) is defined as the ratio of actual evaporation over potential evaporation under the same atmospheric conditions. The use of KE provides an alternative means for evaluating soil moisture status and quantifying soil evaporation by reducing in situ measurements. However, little effort has been made to evaluate the estimation of KE over soil surfaces. In this study, a re...
متن کاملMeasuring evaporation from soil surfaces for environmental and geotechnical purposes
There are many reasons for the need to assess rates and quantities of evaporation or evapotranspiration from natural soil surfaces, the surfaces of deposits of mine or industrial waste, or soil-covered waste surfaces. These include assessing water balances for nearsurface soil strata, landfills, tailings dams and waste dumps and suitable deposition or application intervals for hydraulic fill ta...
متن کاملModeling soil evaporation efficiency in a range of soil and atmospheric conditions using a meta-analysis approach
A meta-analysis data-driven approach is developed to represent the soil evaporative efficiency (SEE) defined as the ratio of actual to potential soil evaporation. The new model is tested across a bare soil database composed of more than 30 sites around the world, a clay fraction range of 0.02–0.56, a sand fraction range of 0.05–0.92, and about 30,000 acquisition times. SEE is modeled using a so...
متن کاملToward a phenomenological theory of nucleation
Nucleation plays an important role in various contexts ranging from formation of atmospheric aerosols to material processing. A quantitative description of these processes often requires an accurate estimate on the rate of nucleation as an input. Classical nucleation theory has been used extensively in practice to predict this quantity. The essential content of classical theory is as follows. T...
