Inverse modeling of groundwater flow in the Rhône alluvial aquifer - impact of the Third Rhône correction

Glenz, Damian ; Renard, Philippe (Dir.) ; Perrochet, Pierre (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2013.

The main objective of this thesis is the quantitative evaluation of the impact of the Third Rhône correction (PR3) on groundwater within the Rhône alluvial aquifer. PR3 is a river restoration project which aims at improving flood protection and at upgrading the ecologically deficient streambed of the Rhône River (Valais, Switzerland). The approach taken to extend the drainage capacity of the...

Hydraulic testing of low-permeability formations: A case study in the granite of Cadalso de los Vidrios, Spain

Mejías, Miguel ; Renard, Philippe ; Glenz, Damian

In: Engineering Geology, 2009, vol. 107, no. 3-4, p. 88-97

In recent years, the study of low-permeability geological formations has undergone considerable development. This is mainly due to the use of natural geological barriers to confine waste disposals, preventing leaking water from bringing contaminants into contact with the biosphere and the groundwater resources. In that context, the Spanish Geological Survey (IGME, Spanish acronym), supported...

Understanding diagnostic plots for well-test interpretation = Comprendre l’utilisation des graphes de diagnostic pour l’interprétation des essais de pompage

Renard, Philippe ; Glenz, Damian ; Mejias, Miguel

In: Hydrogeology Journal, 2009, vol. 17, no. 3, p. 589-600

In well-test analysis, a diagnostic plot is a scatter plot of both drawdown and its logarithmic derivative versus time. It is usually plotted in log–log scale. The main advantages and limitations of the method are reviewed with the help of three hydrogeological field examples. Guidelines are provided for the selection of an appropriate conceptual model from a qualitative analysis of the...
