Hydrogeological and topographical controls on catchment dynamics and their implications for low flows

Carlier, Claire ; Brunner, Philip (Dir.) ; Hunkeler, Daniel (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2018.

Periods with scarce precipitation will likely occur more frequently and last longer under changing climatic conditions, even in relatively humid regions like Switzerland. To assess the sensitivity of water resources to dry spells and to identify regions that might experience water scarcity issues, a thorough understanding of the mechanisms governing catchment dynamics in the absence of rain is...

Advances in characterizing surface water-groundwater interactions : combining unconventional data with complex, fully-integrated models

Schilling, Oliver S. ; Brunner, Philip (Dir.) ; Hunkeler, Daniel (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2017.

The characterization and simulation of the interactions between surface water and groundwater require observations of hydrological state variables and flow processes. While the latest generation of physically-based flow models allows the integrated simulation of all relevant hydrological processes, the current modelling practice is not adequate to provide reliable predictions. Numerous studies...

Numerical simulations and uncertainty analysis for assessing spatial and temporal dynamics in alluvial river-aquifer systems : an application in the context of the 3rd Rhône River Correction

Gianni, Guillaume ; Brunner, Philip (Dir.) ; Perrochet, Pierre (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2017.

Characterizing river-groundwater interactions in alluvial aquifers is essential when forecasting the impact of river management strategies, such as river restorations, on the overall water resources distribution and dynamics. Therefore, the development of methods and calibration approaches that allow for better identification of the spatial and temporal characteristics of the hydraulic properties...

Estimation et cartographie de la vulnérabilité des aquifères en milieu forestier

Thüler, Lorienne ; Brunner, Philip (Dir.) ; Zwahlen, François (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2014.

Groundwater vulnerability assessment is a valuable tool to protect groundwater resources against pollution. Through an active protection of vulnerable aquifers, uninterrupted drinking water supply without expensive treatment can be ensured. Many methods for groundwater vulnerability mapping exist, such as EPIK and DRASTIC. However, these are general methods that do not take into account a range...
