H+ observatory
H+ is the French national network of hydrogeological sites. Its main goal is to maintain and coordinate a network of experimental sites that can provide relevant data – including monitoring datasets and long term experiments for characterizing and modeling the water cycle and the transport of chemical substances aquifers. Hence, the coupling of measurements / theories / models is at the core of H+ scientific objectives, with the aim of developing and validating predictive models for subsurface flow and transport processes.
