heal.abstract	The estimation of the wind energy potential or pollutant dispersion in a complex domain requires a reliable knowledge of the wind field, which can be obtained only after the solution of the 3D Reynolds equations; since the numerical solution of the Reynolds equations for complex terrain is computationally expensive, simpler numerical approaches have been developed. This paper compares predictions of the wind field obtained from a simple model, of mass consistent type, with the results obtained after the solution of the full 3D Reynolds equations. The comparison shows that in those parts of the complex terrain in which the flow is accelerating, there are no major differences in predictions between the simple and the complex approach; however, in areas of decelerated flow, the simple approach underestimates substantially the deceleration of the flow field particularly near the ground.	en
