Water Supply Strategies in the Gallo-Roman Town of Cassinomagus (Chassenon, Charente)

The aim of this study was to determine water resources in a shock-metamorphism context (Rochechouart-Chassenon meteorite crater), to investigate the spatial extent of Gallo-roman buried structures of Cassinomagus and to try to understand relationships between various Gallo-roman buildings and water resources. We have conformed to this problematic by the realisation of geophysical surveys.The magnetic and electric surveys and measures of magnetic susceptibility highlight archaeological buried structures as extension of thermae, the organization of domestic dwellings near the monumental complex and the extent of hydraulic structures. Electromagnetic soundings indicate the presence of a subsurface aquifer and reveal connexions between its geometry and the water catchment area.
