Abstract EN
The French Atlantic marshlands, reclaimed since the Middle Age, have been successively used for extensive grazing and more recently for cereal cultivation from 1970.
The soils have acquired specific properties which have been induced by the successive reclaiming and drainage works and by the response of the clay dominant primary sediments, that is, structure, moisture, and salinity profiles.
Based on the whole survey of the Marais Poitevin and Marais de Rochefort and in order to explain the mechanisms of marsh soil behavior, the work focuses on two typical spots: an undrained grassland since at least 1964 and a drained cereal cultivated field.
The structure-hydromechanical profiles relationships have been established thanks to the clay matrix shrinkage curve.
They are confronted to the hydraulic functioning including the fresh-to-salt water transfers and to the recording of tensiometer profiles.
The CE1/5 profiles supply the water geochemical and geophysical data by their better accuracy.
Associated to the available water capacity calculation they allow the representation of the parallel evolution of the residual available water capacity profiles and salinity profiles according to the plant growing and rooting from the mesophile systems of grassland to the hygrophile systems of drained fields.
