Generally, the capacity of infiltration ability of a region is one of the factors that influence the flooding of the region, this infiltration ability depends on soil characteristics such as soil texture, hydraulic conductivity, soil structure, land cover etc. Winongo watershed is one of the affected areas of Mount Merapi activity so that this condition affects the infiltration which then refers to the flood of Yogyakarta area. This study aims to conduct an assessment of infiltration capacity in areas along the Winongo basin. In this study, the measurement of the rate of infiltration in the field using the Double Ring infiltrometer whereas analytical methods infiltration capacity equation is used Horton where the results of this analysis are then mapped with the help of software ArcMap formulir of interpolation methods, namely: Kriging, Inverse Distance Weighting (IDW) and Radial Basis Function (RBF). The result of this research is the diversity of infiltration capacity value. If Winongo watershed is divided into 3, namely: upstream and downstream, upstream watershed is a high distribution of infiltration capacity with a fragile value of 4,21-5,54 cm / h, low value is in the middle of the catchment area with a vulnerable value of 2,31-3,59 cm / h, and the value is in the downstream area with a vulnerable value of 3,60-4,20 cm / hr with low surface runoff potential.
