Chapter 1: Géneralities Geophysics & Hydro-geophysics

Conventional techniques for characterizing hydrogeological properties (such as pumping, and slug tests) typically rely on borehole access to the subsurface. Because their spatial extent is commonly limited to the vicinity near the wellbores, these methods often can not provide sufficient information to describe key controls on subsurface flow and transport. The natural heterogeneity and the large spatial variability of hydraulic parameters that control infiltration and transport of groundwater is widely recognized.
