“…The groundwater models have been constructed to quality criteria (Hulme et al 2002) that are applied by the Environment Agency to all groundwater models used for catchment management. This includes validation of the groundwater models against observed groundwater level time series and total surface water flow time series measured at gauging stations (streamflow gauges for catchments in the range 30-400 km 2 with data for the last 30-40 years).…”

. Bringing groundwater models to LIFE: a new way to assess water resource management options. Hydrological Sciences Journal, 59 (3-4), 578-593.Abstract If management of water resources is to fully take into account the requirements of the environment, it will benefit from quantitative predictions of the ecological effects of river flow alterations. A significant relationship between flow reductions caused by groundwater abstraction and ecological conditions (as measured by relevant biotic indices) has been shown in streams in the midlands of England. In this article, we combine this relationship with hydrological indices derived from calibrated regional groundwater models to assess river reaches that are likely to be ecologically impacted by abstraction and might consequently be at risk of failing to meet EC Water Framework Directive standards. We demonstrate the application of this method within the framework of the Ecological Limits of Hydrologic Alteration (ELOHA) approach to making water resource decisions. We provide examples of how this approach can be used to assess the implications of different groundwater abstraction scenarios for river water bodies.Key words hydro-ecology; groundwater model; low flows; macro-invertebrates; abstraction Faire VIVRE les modèles hydrogéologiques-une nouvelle façon d'évaluer les options de gestion des ressources en eau Résumé Si la gestion des ressources en eau doit prendre pleinement en compte les besoins de l'environnement, elle bénéficiera des prévisions quantitatives des effets écologiques des altérations des écoulements en rivière. Une relation significative entre les réductions de débit causées par les prélèvements en eau souterraine et les conditions écologiques (telles que mesurées par des indices biotiques pertinents) a été démontrée pour des cours d'eau du centre de l'Angleterre. Dans cet article, nous combinons cette relation avec des indices hydrologiques issus de modèles hydrogéologiques régionaux, calés de manière à déterminer les tronçons de rivière susceptibles d'être impactés écologiquement par les prélèvements et qui, par conséquent, pourraient présenter le risque de ne pas répondre aux normes de la Directive cadre sur l'eau. Nous décrivons l'application de cette méthode dans le cadre de l'approche ELOHA (Ecological Limits Of Hydrologic Alteration-limites écologiques liées aux modifications hydrologiques) pour la prise de décision sur les ressources en eau. Nous fournissons des exemples sur la façon dont cette approche peut être utilisée pour évaluer les conséquences de différents scénarios de prélèvement d'eau souterraine sur les cours d'eau.

“…The national modelling framework outlined by Brown & Hulme (2001) and reported by Hulme et al (2002) provides a technical and management approach to individual projects as part of planned regional modelling strategies. Each of the seven regions of the Environment Agency in England and also the Environment Agency Wales (Fig.…”

“…(1) the national programme has been led by the powerful national environmental regulator, the Environment Agency for England and Wales; (2) there has been collaboration between the regulator and water companies so that any arguments are not about which model to use; (3) a national modelling framework has been developed including Modelling Guidance Notes produced and revised over the years by a group of about 20 -30 practitioners from the regulator, universities and consultants (Hulme et al 2002); (4) the Environment Agency has invested in modelling training in collaboration with universities, as part of provision for a modular Masters degree in Environmental Engineering; (5) a central server system (the National Groundwater Modelling System) has been developed, with the aspiration to make model results more readily available in the UK where data are not accessible, unlike other countries such as the USA, where access to data is widely available.…”

“…To address this, the Environment Agency initiated a national technical framework for groundwater modelling, reported by Hulme et al (2002), to provide a set of standards and practices to minimize these problems. Skinner (2008) reported that, because of the existence of national standards and common practice, the work done by the Environment Agency, water companies and other private industry is more likely to be complementary in the same or adjacent areas and increases the level of factual consensus on which planning decisions can be taken.…”

Over the last 10 years there has been a unique regulator-led programme involving extensive development of regional groundwater models across England and Wales for water resources purposes by the Environment Agency for England and Wales. Eight regionally managed programmes are underpinned by a framework, which has allowed a coordinated national approach. The main uses of the models are for catchment abstraction management and licensing. Models have also assisted in monitoring network design, investigating groundwater quality and implementing groundwater source protection zones. A five-yearly review of the programmes recognized the importance of benefit realization and stakeholder involvement as well as technical good practice. The programme already delivered provides a solid foundation for supporting the management decisions required in areas such as climate change mitigation and integrated catchment management using appropriate tools at a time of rapid organization change and financial uncertainty.

“…It was in a response to those challenges that the Environment Agency, which had become the environmental regulator for England and Wales in 1996, initiated a programme of work to develop a more consistent, cooperative and sustainable approach to groundwater modelling (Hiscock et al 2002;Hulme et al 2002a;Grout et al 2004). The key challenge was the development of models at the requisite standard across the Environment Agency that were acceptable to the various stakeholders.…”

A national approach to groundwater modelling: developing a programme and establishing technical standards

In the 1970s regional groundwater modelling began to be used in support of many hydrogeological investigations in the UK. A number of the studies were concerned with groundwater development at a regional scale in conjunctive use schemes; elsewhere the effect of pumping from aquifers on river flows or the ingress of saline water was considered. Due to the limited power of digital computers at that time, special numerical codes were often prepared for individual projects, with consequent inefficiency and inconsistency of practice. However, by the mid 1990s the need to formalize and standardize groundwater modelling projects was recognized. The Environment Agency of England and Wales prepared a strategy to manage and monitor the projects. A Template Project Brief was prepared to define the many tasks involved in groundwater studies and to clarify the roles of contractor and client (Environment Agency). In addition Guidance Notes were prepared to disseminate procedures and techniques that had resulted in successful outcomes. This paper summarizes some of the earlier studies, provides information about the Project Brief and Guidance Notes and illustrates some critical issues in groundwater modelling by reference to two case studies.
