Abstract: The hydrological processes in the urban drainage are known as rainfall, runoff, and infiltration. This research aims to find out how the relationship of soil density, initial moisture content, and slope of lands influences the rain, runoff, and infiltration process. This research is conducted in a laboratory using a rainfall simulator plot tank. The size of the plot tank is 1. 17 m x 0. 97 m x 0. 30 m. The plot tank is filled with soil of the same specific gravity for different initial water content in soil compaction land slope variation. The experiment carried out on steady rain intensity where every point in the plot is assumed to have uniform velocity. The method describes the compaction of urban land using prototype that influences the infiltration rate. Runoff processes. Infiltration rate was calculated by reducing intensity of rain and runoff as output data from a running rainfall simulator. The processes are explained in water balance concept in urban drainage. Based on the results of the study, the compaction and the slope will positively affect against the runoff where the higher the compaction, the greater the runoff will be. However, it will negatively affect the infiltration
