Data of The effect of rainfall intensity on the threshold for generation of saturation excess overland flow on steep hillslopes

Simulated storage threshold for saturation excess overland flow TSO, occurrence time T and water table height h on twenty-five hillslopes by kinematic wave analytical solutions (KW) and Boussinesq numerical solutions (BS) under rainfall rates from 1mm/h to 20mm/h.The rainfall intensity threshold N0, its corresponding storage threshold TSO0, and occurrence time T0 of 25 hillslopes simulated by the two methods are also given.
