Micro‐relief surface depression storage is one of the dynamic components of the rainfall‐runoff process. The quantification of the effect of rainfall intensity and duration on the micro‐relief was the subject of this study. Micro‐relief measurements were made on 88 soil bin samples before and after the application of simulated rainfdl events. The surface depression changes are described with empirical equations, using basic rainfall, surface hydrology, and soil parameters and their cross products as independent variables. A rainfall‐runoff model demonstrates the value of a dynamic description of the surface depression storage function.
