The terrain slope is a real-world feature. In this study, the effect of a slight terrain slope on the flow structure is studied in connection with the problem of the urban heat island by a proposed two-length scale κ-ε model. Findings indicate that even a slight slope can cause appreciable change in the flow structure. The degree of alteration depends on both the slope and the temperature difference between the rural and urban area
