| 内容記述 | The number of lakes in Japan is about 600, which are recognized on the 1/50,000 map published by the Geographical Survery Institute of Japan. About 150 lakes among 600 were investigated and their lake basins were reprorted (Fig. 1). The author selected so called “closed (without outlet) lake” from these lakes. The annual water balance of selected lakes are given by : G_O=(P-E_A)・S_A・f+(P-E_L)・S_L where G_O is groundwater outflow from the lake (㎥・year^-1), P is precipitation (m・year^-1), E_A is evapo-transpiration from the catchment area (m・year^-1), S_A is catchment area (㎡), E_L is evaporation of water from lake surface (m・year^-1) and S_L is area of lake (㎡). In this paper, the author make the assumption that G_O is equal to the water depth of leakage of the closed lake. The results of calculated water balance are shown in Tables 1 and 2. The lakes in Table 1 are crater lakes, caldera lakes and maars by volcanic activity. The lakes in Table 2 are in non-volcanic region. The purpose of this paper is clarify conditions of location of closed lake in Japan through water balance consideration. The results are summarized as follows ; 1) In volcanic region, caldera lakes show lower value of leakage. For example, the depth of leakage in Lake Mashu-ko (V-1) is 0.58 m・year^-1. Maximum value is 87.47 m・year^-1 on Lake Hiki-numa (V-44). In non-volcanic region, the depth of leakage is comparatively high. This values ranges 3.77 m・year^-1 to 129.38 m・year^-1. Minimum value is Lake Menkozaka-no-ike (N-1) and maximum is Lake Wakahata-numa (N-25). 2) The depth of leakage can be derived from field observations (e.g. Okada, 1985, 1987, 1988). These values are 14.24 m・year^-1 in Lake Sai-no-ko, 9.13 m・year^-1 in Lake Kirigome-ko Karigome-ko and 5.11 m・year^-1 in Lake Shibire-ko. The calculated values for these lakes are 34.07, 45.24, 6.30 m・year^-1, respectively. However, these may be overestimated, because the geological structure around the lakes is not taken into consideration. The condition of location of closed lake is closely related to the origin of lake to some extent. | |||||
