The purpose of authority control is to ensure consistency in representing a value - a name of a person, a place name, or a term or code representing a subject - in the elements used as access points in information retrieval. The primary purpose of this study is to produce a framework that will provide a clearly stated and commonly shared understanding of what the subject authority data/record/file aims to provide information about, and the expectation of what such data should achieve in terms of answering user needs.

In the alluvial plain of the river Meuse, in the area of Jupille-sur-Meuse in Liège, the construction of a short-tunnel is foreseen, at the intersection between Avenue Georges Truffaut and Avenue of Jupille.
For this reason, this Master Thesis work focuses on the numerical simulation of the alluvial aquifer behaviour by establishing a groundwater flow model of the concerning area. The model is carried out with the use of GMS-MODFLOW, using the finite difference technique to conceptualize the reality.
The aim is to investigate whether the presence of the foreseen short-tunnel modifies the natural groundwater flow in the aquifer and if it could lead to possible consequences on the pumping activity of the Jupiler brewery located not far and which strongly affects the piezometric levels. 
Different scenarios will be simulated, according to the different construction approaches that may be performed for the short-tunnel during the construction phase and at the end of the construction phase. 
The flow budget concerning the needed withdrawals from the excavation area to guarantee a dry and safe work condition is also studied. In this way, it is possible to detect the influence in choosing the dimension of the cut-off walls used for the excavation. If the walls reach the bedrock (here considered as impervious) the groundwater is totally or partially blocked by the walls, and then the dewatering wells (during the construction phase) and the drainage system (at the end of the construction phase) can pump water only inside the zone enclosed by the barriers.
Furthermore, the sensitivity analysis on the conductance value between the river and the aquifer and then between the drainage system and the aquifer is performed.
Lastly, this area may be a potential site for the development of geothermal open systems, thanks to the geological and hydrogeological properties of the alluvial aquifer. In this Master thesis work, the opportunity will be taken to use also the model in order to investigate the influence of a doublet with a pumping well and injection well. Different scenarios will be simulated to investigate the alluvial aquifer behaviour and also to assess the influence on the pumping wells of the Jupiler brewery. The study of those scenarios serves to lay the foundation for further analysis in the exploitation of the site in the field of geothermal energy.

The UNIMARC Authorities Format was designed in the early 1990's to allow the creation of authority and reference records for the management of controlled access points in a bibliographic database. Incorporated in this work is relevant information from other IFLA working groups and from UNIMARC users. It is published under the auspices of the IFLA Cataloguing Section. This is the 3rd, completely updated and enlarged edition.
