SPATIOTEMPORAL VARIATIONS IN THE IMPACTS OF URBAN LAND USE TYPES ON URBAN HEAT ISLAND EFFECTS: THE CASE OF RIYADH, SAUDI ARABIA

We developed and tested a conceptual model to estimate depression storage capacity (DSC) having small roughness values usually encountered in rainwater harvesting microcatchments in arid regions with only one fitting parameter. Results indicated that the developed linear model between DSC and the square root of the ration of random roughness (RR) to slope was significant. The model predicts depression storage of small relief at higher accuracy compared to other models found in the literature.
