Groundwater provides a significant proportion of water supplies in the UK and the majority of our domestic water in many parts of southern, south-eastern and eastern England. It is an important source for agricultural irrigation and for industry in the UK. It supports flow in many of the UKs most iconic rivers, such as the Chalk streams of the Chilterns and the North and South Downs, maintaining healthy ecosystems, and providing amenity value and supporting livelihoods associated with those groundwater-dependent rivers. When managed appropriately, it is a dependable, resilient source of water. However, due to natural year-on-year variations in rainfall, it is susceptible to major droughts. For example, during the last major groundwater drought in the UK in 2010-12 seven water companies in south and east England had to impose temporary use bans (colloquially known as 'hosepipe bans') on about 20 million people in spring of 2012 with the environment and farming sectors also significantly adversely affected by restrictions on their use of water. Consequently, there is a need for a much better understanding of groundwater droughts and their impacts to support improvement in planning for and managing groundwater droughts in the UK. Groundwater droughts are defined as below normal levels of groundwater and have a number of unwelcome effects, such as reduced production of groundwater from boreholes, and the drying up of groundwater-dependent rivers with resulting implications for wildlife and livelihoods. The Natural Environment Research Council is currently funding the 'UK Droughts and Water Scarcity Programme' providing strategically important research to improve characterisation and prediction of episodes of drought in the UK. However, major episodes of drought take time to develop and affect large areas. For example, when there is a long groundwater drought in the UK, e.g. 2010-12, that same drought also affects large parts of continental Europe. As a result, there is significant benefit to be gained for the UK by understanding the development and impacts of major droughts at the European scale. However, there is currently no co-ordination of relevant groundwater information or groundwater drought research across Europe, and currently groundwater drought status cannot be monitored or its impacts assessed at the continental scale. This project, the Groundwater Drought Initiative (GDI), aims to address these shortcomings leading to significant improvements in groundwater drought characterization and impact assessment for the UK and continental Europe. The GDI will build on and add value to two existing NERC-funded projects (the Historic Droughts and IMPETUS projects) in the current NERC UK Droughts and Water Scarcity Programme and will work with partners from BOKU, Austria; University of Rouen, France; University of Freiburg, Germany; University of Oslo, Norway; Wageningen University, Netherlands; Comenius University, Slovakia; and, CISC, Spain as well as other researchers across Europe. The GDI will produce and publish the first pan-European assessment of groundwater drought status (from 1960 to present), and will analyse the most recent European groundwater droughts. The GDI will investigate what groundwater droughts mean for people - for the first time systematically investigating the impacts of recent groundwater droughts by comparing the results of the new European-scale groundwater drought status assessments with information about impacts of previous recent droughts held in an existing on-line database (the European Drought Impact Report Inventory, EDII). Central to all the activities of the GDI will be the establishment of a new network to co-ordinate the work of groundwater drought specialists and related data and information across Europe, ensuring the dissemination, use and maintenance of the common resources to enable future impactful research into groundwater droughts.

地下水在英国提供了相当一部分的水供应，以及我们在英格兰南部，东南部和东部许多地区的大部分家庭用水。它是英国农业灌溉和工业的重要来源。它支持许多UKS中最具标志性的河流中的流动，例如Chilterns和North and South Downs的粉笔流，维持健康的生态系统，并提供与地下水依赖河流相关的舒适性价值并支持生计。当适当地管理时，它是一种可靠的弹性水源。但是，由于降雨的同期自然变化，这很容易受到重大干旱的影响。例如，在2010 - 12年英国的最后一次重大地下水干旱期间，南部和东英格兰的七家自来水公司不得不在2012年春季施加临时使用禁令（通俗被称为“软管禁令”），该公司在环境和农业领域的限制也对水的限制产生了严重的不利影响。因此，需要更好地了解地下水干旱及其影响，以支持在英国为计划和管理地下水干旱的改进和管理。地下水干旱的定义为低于正常水平的地下水，并且具有许多不受欢迎的作用，例如钻孔的地下水产量降低，以及地下水依赖性河流的干燥，对野生动植物和生计产生了影响。自然环境研究委员会目前正在资助“英国干旱和水短缺计划”，提供了具有战略意义的研究，以改善英国干旱发作的特征和预测。但是，干旱的主要事件需要时间来发展和影响大面积。例如，当英国发生长期的地下水干旱时，例如2010-12，同样的干旱也影响了欧洲大陆的大部分地区。结果，通过了解欧洲规模的重大干旱的发展和影响，为英国带来了可观的好处。但是，目前尚无欧洲相关地下水信息或地下水干旱研究的协调，目前无法监测地下水干旱状况或在大陆规模上评估其影响。该项目是地下水干旱倡议（GDI），旨在解决这些缺点，从而对英国和欧洲大陆的地下水干旱表征和影响评估进行显着改善。 GDI将在当前的NERC英国干旱和水稀缺计划中建立并为两个现有的NERC资助项目（历史干旱和动力项目）增值，并将与奥地利Boku的合作伙伴合作；法国鲁恩大学；德国弗雷堡大学；奥斯陆大学，挪威；荷兰瓦格宁根大学；斯洛伐克的科尼乌斯大学；以及西班牙以及欧洲其他研究人员的CISC。 GDI将制作并发布第一次对地下水干旱状况的泛欧评估（从1960年到现在），并将分析最近的欧洲地下水干旱。 GDI将研究地下水干旱对人们的意义 - 首次系统地研究了新的地下水干旱的影响，通过比较新的欧洲规模的地下水干旱状况评估的结果与有关现有的在线数据库中现有的近期干旱的影响的信息（欧洲影响报告库库存，EDII，EDII）。 GDI的所有活动的中心将是建立一个新网络，以协调欧洲整个欧洲地下水干旱专家以及相关数据和信息的工作，以确保对共同资源的传播，使用和维护，以使未来有影响力的研究对地下水干旱。
