The Groundwater Governance Project by Global Environmental Facility and other international organizations from 2011 to 2014 comprehensively reviewed the current status of groundwater governance all over the world and concluded that it is still far from an ideal state. In the case of Japan,top-down regulations by national and local governments have been the main way for groundwater management traditionally. However,there have been moves to adopt the concept of groundwater governance recently. This paper gives a brief overview of groundwater management in Japan based on \"four components of governance\" by the Groundwater Governance Project actors; legal, regulatory and institutional frameworks; goals, policies and plans; and information,knowledge and science and discusses the significance and issues of introducing the concept of groundwater governance.","PeriodicalId":173171,"journal":{"name":"Journal of groundwater hydrology","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117123929","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 FEFLOW code was used to solve density-dependent groundwater flow and mass transport in unsaturated-saturated porous media. The simulations indicated that the maximum amount of seawater intrusion during the tsunami was controlled by the total unsaturated void space of the soil beneath the inundation area. After the tsunami, directions of seawater movement and flushing time depended on the pre-tsunami groundwater flow conditions and bedrock structures. Some groundwater was found to be survived from salinization, and showed the potential to provide water supply in an equivalent amount of the pre-tsunami level without worsening the recovery process. The simulated attempt to remove the intruded seawater from a polluted well could accelerate aquifer recovery but might not be practical due to the cost of maintaining intensive pumping over years.","PeriodicalId":173171,"journal":{"name":"Journal of groundwater hydrology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116232008","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}

Based on a change (multiple stratification) of policy agenda on groundwater in Japan,we suggest that social value of groundwater is a key concept to grasp related cases comprehensively. The types of reaction to social value include countermeasures against social loss,avoidance of social loss and creation of social value. We clarify the degree of groundwater governance is stronger with expansion of those types of social value. A change of groundwater management is another topic,we clarify how that change reflects the characteristics of groundwater governance which consist of multi-actor,multi-level and policy mix through some case studies of groundwater infrastructure.","PeriodicalId":173171,"journal":{"name":"Journal of groundwater hydrology","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114446417","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}
