“…The dominant direction of groundwater movement in the shallow aquifer is longitudinal to the stream at this site rather than transverse to the stream (from field to stream) as is more commonly observed (e.g., Vidon and Hill, 2004). This drainage pattern has implications for the movement of contaminants in the landscape.…”

Riparian wetlands can act as both phosphorus (P) sources and sinks depending upon a range of factors that affect hydrological and biogeochemical processes that govern P mobilization. Stream flow, groundwater levels and water chemistry (total P (TP), soluble reactive P (SRP)) were measured in a series of nested piezometers along three transects located in a riparian zone prior to and throughout a flood event resulting from the release of water from an upstream reservoir. Results of the study show that the stream was influent on all sampling dates, and groundwater flow through the riparian zone was longitudinal to the channel, rather than transverse to the stream. This drainage pattern affected riparian zone biogeochemistry. The riparian zone was a source of TP and SRP to the shallow groundwater system under both pre-flood and flood conditions, as P levels were higher in piezometers at the downstream end of the riparian zone (p B0.001). Flooding induced a brief increase in TP concentrations in shallow groundwater due to mixing with surface runoff following overbank flooding; however, these concentrations quickly returned to pre-event levels. In contrast, SRP concentrations in shallow groundwater decreased during flooding, likely resulting from mixing with oxygen-rich stream water. A large pulse of TP (12,000 mg L(1 ) was observed in the creek on the peak flood date. This P did not originate from the reservoir and was more likely due to the mobilization of P from the riparian zone surface when overbank flooding occurred. The results indicate that autumn flooding of riparian zones downstream from impoundments may mobilize phosphorus if overbank flooding occurs, thereby reducing the nutrient retention potential of riparian zones in some settings.Ré sumé : Les milieux humides riverains, sous l'influence des facteurs hydrologiques et biochimiques, responsables de la mobilisation du phosphore (P), peuvent agir en tant que source et puits de P.

“…Even maps at the 1:10 000 to 1:20 000 scale may have limitations when determining the topography of riparian areas and adjacent upland perimeter slope (Vidon and Hill, 2004b). At such scales the contour interval is 5 m, and riparian areas with less than 5 m difference in elevation between the upland and riparian area cannot be delineated.…”

Nutrient dynamics, transfer and retention along the aquatic continuum from land to ocean: towards integration of ecological and biogeochemical models

Abstract. In river basins, soils, groundwater, riparian zones and floodplains, streams, rivers, lakes and reservoirs act as successive filters in which the hydrology, ecology and biogeochemical processing are strongly coupled and together act to retain a significant fraction of the nutrients transported. This paper compares existing river ecology concepts with current approaches to describe river biogeochemistry, and assesses the value of these concepts and approaches for understanding the impacts of interacting global change disturbances on river biogeochemistry. Through merging perspectives, concepts, and modeling techniques, we propose integrated model approaches that encompass both aquatic and terrestrial components in heterogeneous landscapes. In this model framework, existing ecological and biogeochemical concepts are extended with a balanced approach for assessing nutrient and sediment delivery, on the one hand, and nutrient in-stream retention on the other hand.

“…However, the effectiveness of this instrument is dependant on local conditions. For example, where the hydrological pathway is groundwater driven the riparian buffer zone has the potential to be bypassed (Bohlike and Denver, 1995;Vidon and Hill, 2004). Other research has shown that a riparian buffer zone can lead to pollution swapping.…”

In the European Union, mitigation measures to abate diffuse pollution from agricultural land are implemented under the direction of the EU Nitrates and Water Framework Directives. As these measures are implemented in national policies, a review process will look at the efficacy of the measures with a view to recommending further measures as necessary and following scientific and stakeholder consultation. Riparian buffer zones, beyond those zones used as mandatory set back distances for fertiliser and organic manure spreading, have been used as filters in some countries to attenuate nutrient rich runoff and may be proposed as supplementary measures elsewhere. Notwithstanding the ongoing research on the physio-chemical efficiency of riparian buffer zones, this study examined the willingness of farmers to adopt such features on agricultural land. The sample size was 247 farmers in 12 catchments (approximately 4-12km 2 ) in the Republic of Ireland. The survey was based on a proposal to install a 10 metre deep riparian buffer zone on a five year scheme and the analysis was based on principal components analysis, contingent valuation methodology and a Generalized Tobit Interval model. Results from this analysis indicated that famers' willingness to supply a riparian buffer zone depended on a mix of economic, attitudinal and farm structural factors. A total of 53% of the sample indicated a negative preference for provision. Principle constraints to adoption include interference with production, nuisance effects and loss of production in small field systems. Of those willing to engage with supply, the mean willingness to accept based cost of provision for a 10 metre riparian buffer zone was estimated to be €1513 ha -1 per annum equivalent to €1.51 per linear metre of riparian area.
