Hot spring water quality was classified by five groups (G 1 , G 2 a, G 2 b, G 2 c, and G 3 ). G 1 and G 2 a are distributed in the Kamegawa thermal zone, and G 3 and G 2 c are mainly found in the Beppu thermal zone. G 2 b is observed in both thermal zones. The water types of the hot springs were almost consistent with those in the 1980 s but changed from Cl to HCO 3 type in the Beppu thermal zone. The vertical distribution of the hot springs implies that there are two distinct flow paths in the Beppu thermal zone, and confirmed the seawater mixing in the well located near the shore. The mixing rate between the seawater and hot spring water was calculated by Cl － concentration, which was 12 % of seawater.","PeriodicalId":173171,"journal":{"name":"Journal of groundwater hydrology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128677267","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Groundwater is managed by two kinds of organizations, the land improvement district that has the responsibility for sending irrigation water to the entire command area through principal distributing systems, and the farmers or the water users associations that irrigates paddy plots in the terminal command areas controlling terminal division works and groundwater pumping wells. Groundwater use in the entire command area compensates for the shortage of surface water intake and complements the fluctuation of surface water intake due to meteorological conditions. Water managers use groundwater with excellent handleability responding to the changes in precipitation and situation of rice growth stages in the terminal plots. The appropriate division of roles and cooperative works among the two different organizations are important for desirable agricultural groundwater management.","PeriodicalId":173171,"journal":{"name":"Journal of groundwater hydrology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121371035","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The unconfined groundwater level was periodically fluctuated between 40 m and 50 m above sea level and indicated the maximum value in October or November and the minimum value in April or May. Annual effective precipitation was related to the maximum groundwater level in each year and it had decreased 0 . 7 mm every year. The urban area was slightly increased from the 1970 s to 2016 , but it was not a factor to decrease the unconfined groundwater level. The hot spring yield was inversely related to the maximum groundwater level in each year and it had increased 7 . 9 mm/y, which is approximately 11 times higher than the effective precipitation. Thus, it could conclude that the increase of the hot spring yield mainly affected the decline of the unconfined groundwater level from 1971 to 1999 .","PeriodicalId":173171,"journal":{"name":"Journal of groundwater hydrology","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129787703","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
