This paper proposes an analytical method of the variation of ground-water level due to the discharge of ground-water in industrial areas or due to the change of the water level in a surface reservoir and presents some examples in Yamato Basin, Nara prefecture. The characteristics of the method are to introduce the conception "quasi-depth" and to use numerical analysis. Those are as follows : (1) In most alluvial plains the strata are so complicated that the permeability and the depth cannot be surveyed continuously. So instead of them the authors introduce the quasi-depth which means permeable capacity and is determined easily from the ground-water level map and a few boring data. (2) Even if the permeable capacities were determined most of them would be so irregular and complicated that we cannot treat these problems theoretically. So the authors use numerical analysis to calculate the variation of ground-water level. By this analytical method, the authors can find out the behaviors of the variation of ground-water level in comparatively wide areas. As the result, the plan on the long period use of ground-water can be formed.
