Abstract

To reclaim the lakes to their pristine conditions, it is essential to examine the environment where the lakes occur and rejuvenate natural water circulation. As an attempt to achieve this target, a program is planned for the western shore area of Kitaura utilizing groundwater with the knowledge of its flow system. In the program, a water amenity park/lakeside bathing resort is planned with the flowing wells as source of water. To measure aquifer coefficients, flow tests of wells, which have been done rarely in Japan, were carried out in the area. The flow tests using flowing wells do not need lifting pumps in contrast to the tests of ordinary wells, and because of that aquifer coefficients can be obtained by just measuring the amount of discharge. A method of calculation, for how many mutually interfering flowing wells are to be required to secure necessary amount of water for the water amenity park/lakeside bathing resort, is presented based on the result. The amount of total discharge for the group of flowing wells is examined using the calculated result. <br>
