Landward Perspective of Coastal Eutrophication Potential Under Future Climate Change: The Seine River Case (France)

Carbon Dynamics Along the Seine River Network: Insight From a Coupled Estuarine/River Modeling Approach

“…pyNuts-Riverstrahler is a modeling environment written in python (the "py" prefix), setting up the Riverstrahler generic model of water quality for describing the cycling of carbon and nutrients ("Nuts" suffix) in large river systems (Billen et al, 2015(Billen et al, , 2018Raimonet et al, 2018). Biogeochemical processes are simulated within the water column (assumed perfectly mixed), at the water-atmosphere interface (for gaseous variables), at the interface with benthic sediments (see Billen et al, 2015), and at the interface with terrestrial part of the watershed, namely the riparian zone (see Billen et al, 2018).…”

“…The genericity of the Riverstrahler model has been demonstrated throughout successful applications to contrasted fluvial basins, from temperate climate including (among other) the Moselle (Garnier et al, 2000), the Danube (Garnier et al, 2002), the Scheldt (Thieu et al, 2009) among other, sub-tropical climate as the Red River (Le et al, 2014) or the Nam Kan river (Causse et al, 2015) and or under nordic climate, such as the Kalix and Lule rivers (Sferratore et al, 2008) and the Seine river (Raimonet et al, 2018). The Riverstrahler model has also been chained with the coastal marine model (ECO-MARS3D, Cugier et al, 2005), extended to the estuarine part in terms of hydrosedimentary representation (Passy et al, 2016), and with nutrient description (Romero et al, 2018).…”

“…Here, the application to the Seine estuary-river system of the generic transport reactive model C-GEM (for Carbon Generic Estuarine Model, Volta et al, 2014) combined with pyNuts-Riverstrahler (Thieu et al, 2015;Raimonet et al, 2018) allows understanding the carbonate system dynamics in a well monitored and intensively studied system. Fully transient simulations over the entire year 2010 are performed to quantify the annually integrated CO 2 exchange at the airwater interface and better understand the evolution over the year and along the estuarine-river continuum of the CO 2 exchange with the atmosphere and organic carbon degradation as well as the longitudinal variations of inorganic to organic carbon ratio in response to anthropic pressures.…”

Hydrological Alteration Index as an Indicator of the Calibration Complexity of Water Quantity and Quality Modeling in the Context of Global Change

“…In Europe, the summer water scarcity impacts ecosystems and affects human management over the entire South-Western Europe [4]; (http://www.aguamod-sudoe.eu/en/). Climate change and anthropogenic activities increase the risk of water quantity and quality deterioration [5,6]. The European Union is currently supporting research programs helping regional and local governments to establish and implement policies addressing such environmental issues (i.e., http://www.aguamodsudoe.eu/en/).…”

Hydrodynamic-Based Numerical Assessment of Flood Risk of Tamuín City, Mexico, by Tampaón River: A Forecast Considering Climate Change

“…The outcome shows increments in peak flows and duration of streamflow during the monsoon months, which allow assessing regional socio-economic changes [32]. In [33], biogeochemical and hydrological models were coupled to assess the impacts of CC in coastal eutrophication potential in the Seine River basin, considering the BC-CORDEX projections of precipitation and temperature for RCP4.5 and RCP8.5. The results show more intense extreme streamflow, which results in the degradation of water quality for RCP8.5.…”
