Abstract

This paper reviews methods available for addressing fluxes of water and nitrate, as well as the process affecting nitrate concentrations in the transition from groundwater to surface water, in a comprehensive tabular compilation. Small-scale methods, typically involving direct measurements, give the most quantitative information, while methods working on a larger scale, e.g. airborne or waterborne techniques, can give information on a larger and, in many contexts, more useful scale, but rarely with appropriate quantification. Bridging the gap may be possible by simultaneously applying large-scale measurements and small-scale direct measurements covering the range of values, using these for calibration.
