抄録: | From a series of geological and hydraulic investigations on the groundwater problemsin the inland region around the Lake Biwa, the authors ever assumed the water-tabledepression in the inland accompanied with the variation in the water level of the lakewhich may be expected as low as 3 in. The results were about 3-5 km from the shorein the eastern side of the lake, while as far as about 2km in the western side.The present report treats the mechanism of formation of the water-curtain whichappears on the seepage from a canal when it encounters with the natural undergroundflow at the upstream part of the canal. The phenomena are proved by seepage exper-iments using sand model in the laboratory and also by in-situ tests performed at a shoreof the Lake Biwa. Thus it is concluded that such a mean using recharge canal withsuitable scale can be adaptable to maintain the ground-water level surrounding the lake. |
