| Abstract | There exist 38 boreholes at the Onyang hot spring area and submersible pumps are currently being used in 29 of them. The usage of hot water tends to increase in the spring and decrease in the autumn. This study analyzes the relationship between the pumping rate and the piezometric head. Data for the usage of hot water was collected for 10 months and the change of the piezometric head was observed during the same period. A sine curve (amplitude 1-2 m) of the piezometric head was observed within a day and another sine curve (amplitude 40 m) was observed within a year. The relationship between the pumping rate and the piezometric head was interpreted and its result would be useful to manage hot water resources. |
