A reduction in the water recharge area has been recognized as one of consequences. The purpose this study was to determine condition and distribution zones city. Geographic Information System (GIS) used overlay maps soil type, rainfall, slope, input Spatial Multi-Criteria Evaluation (SMCE). research output map potential City.
