This master thesis analyses the hydrogeological properties that are determining the transport of water and solutes in a limestone aquifer. A closer look is been taken at the hydraulic conductivity and effective porosity of the limestone aquifer through experiments on small scale samples and an iterative process of in situ tests and numerical modelling.
This thesis provides a toolbox to investigate and describe the architecture of the dual porosity system in limestone by gas diffusion through small scale samples. The hydraulic conductivity and effective porosity of small scale samples are determined through indirect and direct measurement methods and visualisation techniques. These hydrogeological parameters are also defined for a limestone aquifer through an iterative process of in situ tests and modelling. These parameters for both scales are compared and connected to each other to conclude this thesis.
