The objectives of this study are to develop an agricultural drought evaluation model based administrative boundaries and to assist the effective drought-related decision-making of local governments. The model which was named ADEM(Administrative Drought Evaluation Model for Paddies) is designed to simulate daily water balance between available water quantities from various agricultural water facilitied such as agricultural drought severity, two indices were defined; One is ADFP (Agricultural Drought Frequency for Paddies) which is calculated with a frequency analysis of monthly water deficit, and the other is ADIP(Agricultural Drought Index for Paddies) with a scale of -4.2~+4.2. The developed model was applied to Yeoju district and showed good correspondence with the historical records of drought.
