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.

地下水提供了英国供水的很大一部分以及英格兰南部、东南部和东部许多地区的大部分生活用水。它是英国农业灌溉和工业的重要来源。它支持英国许多最具标志性的河流的流量，例如奇尔特恩斯河和南北丘陵的白垩溪流，维持健康的生态系统，并提供便利价值并支持与这些依赖地下水的河流相关的生计。如果管理得当，它是一种可靠、有弹性的水源。然而，由于降雨量的自然年际变化，容易遭受严重干旱。例如，在 2010 年 12 月英国上一次地下水严重干旱期间，英格兰南部和东部的七家自来水公司不得不于 2012 年春季对约 2000 万人实施临时使用禁令（俗称“软管禁令”）。环境和农业部门也因用水限制而受到严重不利影响。因此，需要更好地了解地下水干旱及其影响，以支持英国地下水干旱规划和管理的改进。地下水干旱被定义为地下水低于正常水平，并会产生许多不良影响，例如钻孔地下水产量减少，以及依赖地下水的河流干涸，从而对野生动物和生计产生影响。自然环境研究委员会目前正在资助“英国干旱和水资源短缺计划”，该计划提供具有战略意义的重要研究，以改善对英国干旱事件的描述和预测。然而，重大干旱需要一段时间才能发展并影响大片地区。例如，当英国出现长期地下水干旱时，例如2010-12 年，同样的干旱也影响了欧洲大陆的大部分地区。因此，了解欧洲范围内重大干旱的发展和影响将为英国带来巨大的好处。然而，目前整个欧洲还没有协调相关地下水信息或地下水干旱研究，目前无法在大陆范围内监测地下水干旱状况或评估其影响。该项目名为地下水干旱倡议（GDI），旨在解决这些缺陷，从而显着改善英国和欧洲大陆的地下水干旱特征和影响评估。 GDI 将在当前 NERC 英国干旱和缺水计划中的两个现有 NERC 资助项目（历史性干旱和 IMPETUS 项目）的基础上建立并增加价值，并将与奥地利 BOKU 的合作伙伴合作；法国鲁昂大学；德国弗莱堡大学；挪威奥斯陆大学；荷兰瓦赫宁根大学；夸美纽斯大学，斯洛伐克；以及西班牙 CISC 以及欧洲其他研究人员。 GDI 将编制并发布第一份泛欧洲地下水干旱状况评估（从 1960 年至今），并将分析最近的欧洲地下水干旱。 GDI将调查地下水干旱对人们意味着什么——通过将新的欧洲范围地下水干旱状况评估的结果与现有的近期干旱影响的信息进行比较，首次系统地调查近期地下水干旱的影响。在线数据库（欧洲干旱影响报告清单，EDII）。 GDI所有活动的核心将是建立一个新的网络来协调整个欧洲地下水干旱专家的工作以及相关数据和信息，确保公共资源的传播、使用和维护，以实现未来有影响力的研究导致地下水干旱。
