See the H+ Observatory presentation booklet (created in december 2007)

The observation service H+ was created in 2002, with three main goals:

The first goal of the H+ observatory is to maintain and coordinate a network of experimental sites capable of providing data - including chronicles or data on long term experiments - relevant to the understanding of the water cycle and of the traveling of solute elements in aquifers.

The coupling between measurements, theories, and models, is a fundamental goal of the H+ observatory. Modeling at all scales is an essential prediction tool. The Obervatory aims at creating a long term relation between research teams interested in theoretical, numerical, and experimental aspects of transport in heterogeneous media.

The H+ observatory also aims at maintaining a partnership between basic research, university/continuous training, and professional expertise (consulting agencies, water management services). The H+ sites accomodate students and professionals for traineeships on the exploitation of water ressources and the prevention of environmental risks.
