This study has been conducted to find out the location and amount of the subterrain water body developed in the alluvial stratum in Paho-Dong, Sungsee-Myo-n, Dalsung-Kun are. An earlier test drilling was done in this area by R.O.K. Agricultural Promotion Corporation. The area consists of a small river basin and surrounding low hills developed around the junction of the Nakdong and Kumho Rivers. The strata of this area are made of Paldal gravel, Bokhyundong and Banyawol layers which were formed in the cretaceous period of the Meso-saicera or acid dikes and covered with-irregular alluvial layers. The alluvial layer in this area is composed of rather minute particles and proportional electric resistance tests on this layer show $10^2\;-\;10^3\;\Omega/cm$. The drillings up to 12meters deep showed only the sand layer (Form 3 to 26meters in thickness) contains water. The sand layers can not be considered a good water trapping one. Applying the data from the drillings to A.Hazen's equation, $K\;=\;{cd_e}^2\;(0.7\;+0.03t)$ to get the theoretical value of the water infilterated, I calculated it as K=13.92m/day. And again the value was set to Dupuit equation, (equation omitted) to acquire the pumping water amount the result was $Q_1\;=\;77.20\;\textrm{m}^3/day$. When the data-applied to the equation for pumping water amount, (equation omitted), the results were $Q_2\;=\;122.39\;\textrm{m}^3/day$ and K = 38m/day $Q_1\;and;Q_2$ (tow types of pumping water amount) represent proper value decrease and maximum value decrease respectively. Therefore, $Q_2$ is the least amount of water we can pump. The area covers about $1,555,000\;\textrm{m}^2$ and the maximum water needed in this area amounts to $155,000\textrm{m}^3$. That means we have to drill 1,406 pumping wells. It is concluded that undertaking the project in this area is irrational or even desperate and surface water should be developed more favorably.
