Geographers and hydro-geomorphologists from LIVE studied the history of Rohrschollen Island to improve their current understanding of the landscape and anticipate future changes.

Historical, paleo-environmental(1) study

 

A diachronic(2) study based on the compilation of old cards and aerial photographs was coupled with a morpho-sedimentary study conducted on the Bauerngrundwasser. They highlighted the influence of re-structuring work done on the Rhine, reducing the island's alluvial character since the 19th century. reduction in the frequency and intensity of floods, the stopping of morphogenic(3) activity, the sedimentary filling in of hydraulic annexes, the drying of the forest, reduction in exchanges between the water table and the river.

(1) Paleo-environment: study of the environment in the past.
(2) Diachronic: evolution of the landscape at different dates in the past.
(3)Morphogenic activity (in a river context): evolution of the shape of a channel through erosion and the depositing of sediments.

Diachronic evolution of Rohrschollen Island's landscape since the start of the 19th century.
