“…This can lead to different proportions of runoff components in drainage runoff, e.g., sites lying in higher positions on slopes (typically P53) have lower proportions of baseflow and higher numbers of REs. Similar (very variable) proportions of event water (12% to 50%) for similar amounts of precipitation (20 to 30 mm) are reported by other studies [21,[50][51][52]. This variability in REs is more probably caused by diverse hydrological conditions in the catchments preceding the rain, namely, soil moisture, the groundwater level in summer, and snow cover for winter events, than by the intensity of rainfall [51], although some other studies reported contrarily [21,53].…”

Rainfall-runoff events significantly influence water runoff and the loss of pollutants from tile-drained agricultural land. We monitored ten small (4 to 38 ha) tile-drained catchments in Czechia for three to five years (2012 to 2016). The discharge was measured continuously; a regular 14-day scheme of water quality monitoring was accompanied with event sampling provided by automatic samplers in 20 to 120 min intervals. A new semi-automated algorithm was developed for the identification of runoff events (RE) based on discharge and water temperature changes. We then quantified the share of RE on the total runoff and the N and P losses, and we compared six methods for nutrient load estimation on an annual and monthly basis. The results showed considerable differences among the monitored sites, seasons, and applied methods. The share of RE on N loads was on average 5% to 30% of the total annual load, whereas for P (dissolved and total), the share of RE was on average 10% to 80% on the total annual load. The most precise method for nutrient load estimation included the RE. The methods based on point monitoring of the discharge and water quality underestimated the loads of N by 10% to 20% and of P by 30% to 80%. The acquired findings are crucial for the improvement of nutrient load assessment in tile-drained catchments, as well as for the design of various mitigation measures on tile-drained agricultural land.

“…Approximately 80% of watershed B is systematically tile drained, but tile drainage contributions to streamflow will likely be less in headwater watersheds with lower drainage intensities. For example, Kennedy et al (2012) showed that event water contributions to watershed discharge were significantly greater in an intensively drained watershed (70% of the watershed was tile drained) compared to a watershed with lower drainage intensity (30% of the watershed was tile drained). Differences in climate can also potentially influence the amount of tile drainage and its contributions to streamflow.…”

“…Water quality monitoring at the outlet of watersheds with different drainage intensities (Kennedy et al, 2012) and monitoring in nested watersheds (Tomer et al, 2003) have been used to estimate the impact of tile drains on watershed N fluxes. Studies have also calculated tile drainage contributions to watershed N export based on N loads from select tile drains within a watershed (David et al, 1997).…”

“…The issue has long been disregarded by hydrologists dealing with the quantification of input/output water fluxes, and has now rightfully become a cornerstone of hydrochemical studies. Typical applications include both atmospheric compounds entering the catchment through precipitation [Shaw et al, 2008;Godsey et al, 2010] or anthropogenic compounds injected onto the catchment, for example, due to farming activities [e.g., Basu et al, 2010;Rouxel et al, 2011;Kennedy et al, 2012]. Chlorides are an example of solutes which can be considered either geogenic or anthropogenic, because the mass input to the terrestrial part of the hydrologic cycle, whose proper quantification is sometimes problematic [Neal et al, 1988;Tetzlaff et al, 2007;Dunn and Bacon, 2008], originates either from atmospheric deposition and/or from the application of inorganic fertilizers.…”

[1] Travel times are fundamental catchment descriptors that blend key information about storage, geochemistry, flow pathways and sources of water into a coherent mathematical framework. Here we analyze travel time distributions (TTDs) (and related attributes) estimated on the basis of the extensive hydrochemical information available for the Hupsel Brook lowland catchment in the Netherlands. The relevance of the work is perceived to lie in the general importance of characterizing nonstationary TTDs to capture catchment transport properties, here chloride flux concentrations at the basin outlet. The relative roles of evapotranspiration, water storage dynamics, hydrologic pathways and mass sources/sinks are discussed. Different hydrochemical models are tested and ranked, providing compelling examples of the improved process understanding achieved through coupled calibration of flow and transport processes. The ability of the model to reproduce measured flux concentrations is shown to lie mostly in the description of nonstationarities of TTDs at multiple time scales, including short-term fluctuations induced by soil moisture dynamics in the root zone and long-term seasonal dynamics. Our results prove reliable and suggest, for instance, that drastically reducing fertilization loads for one or more years would not result in significant permanent decreases in average solute concentrations in the Hupsel runoff because of the long memory shown by the system. Through comparison of field and theoretical evidence, our results highlight, unambiguously, the basic transport mechanisms operating in the catchment at hand, with a view to general applications.
