Abstract
There exist 5 wells drilled at the Yecheon hot spring area, the distance between the wells is about $159m{\sim}702.6m$. The safe yield of each well is controlled by interference drawdown between a pumping well and an observation well after pumping test. The well No. 2 and the well No. 5 are the closest, at the distance of 159 m; therefore interference drawdown between two wells was occurred considerably. The drawdown of the well No. 2 (an observation well) was 16.67 m; the drawdown of the well No. 5 (a pumping well) was 17.21 m. The degree of the interference is about 97% and the safe yield decreased from $750m^3/day\;to\;24m^3/day$. Significant interference between two wells is due to the fact that the aquifer has 1.5 dimensions.
