Kervidy Naizin site

Kervidy Naizin

For a review of researches conducted on Kervidy-Naizin site see also Gascuel-Odoux et al. (2018) "Evolution of scientific questions over 50 years in the Kervidy-Naizin catchment: from catchment hydrology to integrated studies of biogeochemical cycles and agroecosystems in a rural landscape"

Biogeochemical cycling:

  • processes related to Soil Organic Matter (SOM) and Dissolved Organic Carbon (DOC) transfers (Lambert et al., 2013, 2011; Morel et al., 2009) associated to Rare Earth Elements and emerging pollutants (Drug residuals and fecal indicators) 
  • transfers & transformation of nitrates and nitrogen cascade in agricultural landscape (including the interface between soil and atmosphere)
  • exportation of Phosphorus & suspended sediments (Gascuel-Odoux et al., 2009; Dupas et al., 2015 a,b,c; VongVixay et al., 2018)
  • Linking C-N-P nutrients

Modelling hydrological transfers and associated chemical species:

  • Catchments dominated by subsurface flows and nitrogen transfers (Molénat et al., 2002)
  • Identification of hydrological compartment by deconvoluting storm events (Lambert et al., 2011; Morel et al., 2009; Fovet et al., 2018)
  • Taking into account topography, landscape structures (Viaud et al., 2004) and agricultural practices and systems in models: TNT2 (Beaujouan et al., 2001, Moreau et al., 2013), wetland integration (Montreuil et al., 2010; Oehler et al., 2009) and hedgerows simulation (Benhamou et al., 2013)
  • Impact of climate variability on hydrochemical variability at the outlet (Aubert et al., 2013 a,b,c, 2014; Gascuel-Odoux et al., 2010)
