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

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...

Deterministic and probabilistic numerical modelling towards sustainable groundwater management : application to seawater intrusion in the Korba aquifer (Tunisia)

Kerrou, Jaouher ; Renard, Philippe (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2008 ; Th. 2053.

This PhD endeavours numerical groundwater modelling considering heterogeneous and uncertain hydraulic parameters. It is made of three parts. First, we investigated the effects of dimensionality and heterogeneity of the hydraulic conductivity on dispersive seawater intrusion (SWI) processes. Multiple 2D and 3D unconditional simulations of hydraulic conductivity fields sharing the same statistics...
