Abstract
The characteristics of evaporation from the layers of fallen leaves are studied in laboratory. To investigate the relationship among the rate of evaporation, the weather conditions and the moisture condition of layers, we use a wind tunnel, Temperature, humidity and wind speed are chosen for the index of weather condition, water content is chosen for the index of moisture condition in the layer. The result of this study shows that the rate of evaporation can be express as a function of the weather condition and moisture condition. The relationship obtained by the Iaboratory test is similar to the case of bare soil.
