“…However there are no catchment-scale or experimental data which demonstrate that this zone is effective in mitigating pollutant loads in managed landscapes (Smith et al, 2008). Sprenger et al (2011) found that bank filtration processes are vulnerable to climate change due to the drastically shortened travel time during flood events.…”

This paper reviews the potential impacts of climate change on nitrate concentrations in groundwater of the UK using a Source-Pathway-Receptor framework. Changes in temperature, precipitation quantity and distribution, and atmospheric carbon dioxide concentrations will affect the agricultural nitrate source term through changes in both soil processes and agricultural productivity. Non-agricultural source terms, such as urban areas and atmospheric deposition, are also expected to be affected. The implications for the rate of nitrate leaching to groundwater as a result of these changes are not yet fully understood but predictions suggest that leaching rate may increase under future climate scenarios. Climate change will affect the hydrological cycle with changes to recharge, groundwater levels and resources and flow processes. These changes will impact on concentrations of nitrate in abstracted water and other receptors, such as surface water and groundwater-fed wetlands.The implications for nitrate leaching to groundwater as a result of climate changes are not yet well enough understood to be able to make useful predictions without more site-specific data.The few studies which address the whole cycle show likely changes in nitrate leaching ranging from limited increases to a possible doubling of aquifer concentrations by 2100.These changes may be masked by nitrate reductions from improved agricultural practices, but a range of adaption measures need to be identified. Future impact may also be driven by economic responses to climate change. The study draws on extensive literature mainly from the UK and so presents a UK-based perspective, although literature for other temperate climates is included to augment that from Keywordsthe UK and to demonstrate that the proposed framework and general conclusions have a wider applicability.The principal N input to UK groundwater is derived from manures, fertilisers, sewage sludges and crop residues in agricultural areas (DEFRA, 2006). There are also smaller inputs from urban point sources and aerial deposition (Wakida and Lerner, 2005). N fertiliser can be applied as urea or ammonia, as well as nitrate, but the non-nitrate forms are generally converted rapidly to nitrate in the soils of the UK (MAFF, 1999). A small percentage of applied N is lost to the atmosphere as NH 3 , NO or N 2 O (Destouni and Darracq, 2009;Skiba et al., 1997;Sommer and Hutchings, 1995). A proportion of soil N is leached as nitrate from the base of the soil. This is either stored in, or transmitted through, the unsaturated zone to groundwater. groundwater. They found that although an ensemble average suggests there will be about a 5% reduction in annual potential groundwater recharge across the study area, this was not statistically significant at the 95% confidence level and more importantly observed that the spread of results for simulated changes in annual potential groundwater recharge range from a 26% decrease to a 31% increase by the 2080s, with ten GCMs predicting a decrease and three a...

“…Inferences about the potential impact of future scenarios on pre-and post-treatment systems for BF systems in India can be drawn from various plausible sources/scenarios as well as from published literature on BF and climate change (Schoenheinz, 2004;Schoenheinz & Grischek, 2011;Sprenger et al, 2011). The impact of future scenarios or influencing factors on the quantity and quality of water, the consequent impact on BF systems and the coping strategies as well as potential post-treatment requirements for BF sites in India are described in Table 12.4.…”

“…RBF, which is an important part of managed aquifer recharge (MAR) systems (Rauch-Williams et al, 2010), has been used for water supplies in Europe along the Rhine, Elbe, Danube, and Seine Rivers for over a century (Schubert, 2002;Tufenkji et al, 2002) and it has provided the majority of the drinking water for large cities in Russia (Filimonova and Shtengelov, 2013), the USA Roy et al, 2012), China (Wu et al, 2007) and other countries (Hamdan et al, 2013;Lee et al, 2009;Polomčić et al, 2013;Shamsuddin et al, 2014) over the last few decades. The obvious advantage of RBF is the conjunctive use of infiltrated surface water and groundwater from the alluvial catchments of intake structures (Polomčić et al, 2013), which ensure long-term productivity and stability of the water supply (Sprenger et al, 2011). Additionally, surface water contaminants can be significantly removed or degraded as the infiltrating water moves from the river/lake to the production wells due to a combination of physicochemical and microbiological processes (Hiscock and Grischek, 2002;Maeng et al, 2010;Singh et al, 2010;Weiss et al, 2005).…”

Keywords:Groundwater and surface water interactions Riverbank filtration Riverbed clogging Hydraulic conductivity MODFLOW s u m m a r y A steady-state flow regime in riverbank well fields is often violated by fluctuations in river stages and variations in groundwater extraction. In this study, a criterion of quasi-steady flow during filtration processes at riverbank well fields was introduced. Under the assumption of steady-state flow, an analytical approach for determining the key hydraulic parameters (aquifer transmissivity and riverbed filtration resistance) between a stream and a hydraulically connected aquifer during riverbank filtration was presented. An optimal regular observation network (consisting of the locations of monitoring wells and the observation regime), which is based on the model-oriented approach using an example of a riverbank well field near the Kuybyshev Reservoir, Russia, was designed to minimise the uncertainty in the estimates of hydraulic parameters. The analyses showed that the initial recession in the surface water levels for the simplest constant groundwater withdrawal patterns can be used to determine the key hydraulic parameters; the error in these estimated parameters was less than 7% or 12%, depending on the designed monitoring network. When comparing the two typical monitoring networks, observation line A-A that passes midway through the water supply wells performed better than observation line B-B that passes through the water supply wells when estimating the hydraulic parameters. The results of this study can be used as a reference for designing and optimising a monitoring network that aims to determine the key hydraulic parameters at riverbank well fields.
