- Abstract
Spring water, however, is often formed in complex geological formations and therefore it is difficult to determine the catchment area contributing to the flow. The Sayanokami spring, located in western part of Fukuoka City, Japan, is such a spring and an important water resource for the local agriculture. In order to better understand the hydrological properties of infiltration and groundwater processes for the spring water, 222Rn and tritium were used as tracers. Results showed that the residence time for the spring water is 10 - 20 years. A groundwater model confirmed these results and the travel time from the catchment border estimated to be about 25 years. Using this information the catchment border and uptake area were... (More)

In order to better understand the hydrological properties of infiltration and groundwater processes for the spring water, 222Rn and tritium were used as tracers. Results showed that the residence time for the spring water is 10 - 20 years. A groundwater model confirmed these results and the travel time from the catchment border estimated to be about 25 years. Using this information the catchment border and uptake area were estimated. The method can be used to more efficiently determine catchment area and travel time for groundwater and thus to better manage the spring water.
