Hohrain-Rouffach

Hohrain-Rouffach

The Hohrain-Rouffach vineyard is connected to an artificial wet buffer zone. It enables the quantitative evaluation of matter transfer processes (water, solids, solutes, especially pesticides) in relation to hydrological and agronomic forcing in order to understand, quantify and predict the hydrological and biogeochemical functioning of an agrosystem in perennial culture.

Profile :

Located 15 km south-west of the town of Colmar in Alsace at the head-catchment area, the site is one of the observatories of the Laboratory of hydrology and geochemistry of Strasbourg (UMR7517 CNRS / UNITRA / ENGEES). It was partially equipped in 2003 for the monitoring of nitrates, and then in 2009 for the monitoring of flows and cycles of solutes, including pesticides and metals (Cu, Zn, etc.). The Hohrain’s catchment team is composed of researchers of the LHYGES, lecturers of ENGEES and EPLEFPA, as well as the city of Rouffach and winegrowers in the catchment area. The monitoring of the Hohrain-Rouffach catchment has been developed in the framework of the LIFE Environment project ArtWET (2006-2011), the INTERREG IV PhytoRET (2011-2014) and the PACOV project (2014-2018, AERM), coordinated by the LHyGeS.

RECOTOX site characteristics :

The Hohrain-Rouffach site is a 43 ha head-catchment, that is representative of agriculture, soil (calcareous loess) and of the continental climatic conditions of the Alsatian Piedmont. The site is equipped to quantify solute flows at the catchment scale and the vineyard plot (2 plots equipped). At the catchment’s outlet is an artificial stormwater wetland zone (320 m² and 1,500 m3) studied since 2009 in terms of reactive transport of pesticides and metals at the water / plant / sediment interface.

 

Contribution to RECOTOX dynamics :

The catchment area of Hohrain-Rouffach aims at studying the matter transfer (water, soil, particles and solutes) in relation to hydrological forcing and human activities in vineyards. It aims to understand, quantify and predict the hydrological and biogeochemical functionning of an agrosystem with perennial culture. For 10 years, the catchment has served to collect information on water and chemical flows as well as land use data. A specificity of the catchment is that it enables to investigate the plot – catchment – wetland buffer zone continuum. Among other things, it enables to study the phytoremediation and pesticides degradation potential of the stormwater wetland.
