Rates of water vapor loss, E, through surfactant treated soil mulch of varying porosity and thickness were measured in pots exposed to various wind velocities under a wide range of evaporative demand. Empirical values of constant ‘BD’ obtained from the relation Eo/E = 1+BDZn (where Eo is the potential evaporation from the medium and Zn is the thickness of mulch) were expressed in terms of wind velocity (X1) and porosity mulch (X2). Multiple regression of the type BD = q + q1X1 + q2X2 was used to express BD as a function of wind velocity and porosity of mulch within the range of linearity of the relation Eo/E = f (Zn).
