Nitrogen dynamics in the shallow groundwater of a riparian wetland zone of the Garonne, SW France: nitrate inputs, bacterial densities, organic matter supply and denitrification measurements
riparian zone nitrate removal spatial variations
2009/3/12
This study highlights the role of interactions between surface and sub-surface water of the riparian zone of a large river (the Garonne, SW France). Information is given about the role of surface wate...
A standardised method for measuring in situ denitrification in shallow aquifers: numerical validation and measurements in riparian wetlands

2009/3/12
A tracer test to examine in situ denitrification in shallow groundwater by a piezometer with a packer system used bromide as a tracer of dilution and acetylene (10%) to block the denitrification proce...
Hydrological controls on denitrification in riparian ecosystems
nitrous oxide denitrification
2009/3/6
Nitrous oxide fluxes and denitrification rates were measured in situ over a year at a riparian site in the UK. An exponential relationship was found between denitrification rates and soil moisture, wi...
