16The Upper Rhine alluvial aquifer is an important transboundary water resource. However, as 17 in many alluvial systems, the aquifer inflows and outflows are not precisely known, due to the 18 difficulty in estimating the river infiltration flux and the boundary subsurface flow. To 19 provide a thorough representation of the aquifer system, a coupled surface-subsurface model 20 was applied on the whole aquifer basin, and several parameter sets were tested to investigate 21 the uncertainty due to poorly known parameters (e.g. aquifer transmissivity computed by an 22 inverse model, river bed characteristics). Twelve simulations were run and analysed using 23 standard statistical criteria, as well as a more advanced statistical method, the Karhunen 24 This quantity is larger than estimated in previous studies, but also in agreement with some 32 results obtained during low water periods. This important conclusion highlights the 33 vulnerability of the Upper Rhine Graben aquifer to pollution from the rivers and to climate 34 change since it is highly probable that the rivers' regime from the neighbouring mountain 35 ranges will be affected by a reduced snow cover. 36 37

“…The complexity of approaches for obtaining the climate data series appears to have increased in recent years, ranging from the use of global averages (Loaiciga et al 1996;Zektser and Loaiciga 1993) to the use of regional "bulk" projections (Allen et al 2004;Brouyere et al 2004;Vaccaro 1992;Yusoff et al 2002) to the direct application of downscaled climate data (Jyrkama and Sykes 2007;Scibek and Allen 2006b;Scibek et al 2007;Serrat-Capdevila et al 2007;Toews and Allen 2009) to the use of regional climate models (Rivard et al 2008;van Roosmalen et al 2007van Roosmalen et al , 2009). Some of the early efforts to assess potential hydrologic impacts were reviewed by Gleik (1986).…”

Integrated Groundwater Management

Projected global change includes groundwater systems, which are linked with changes in climate over space and time. Consequently, global change affects key aspects of subsurface hydrology (including soil water, deeper vadose zone water, and unconfined and confined aquifer waters), surface-groundwater interactions, and water quality. Research and publications addressing projected climate effects on subsurface water are catching up with surface water studies. Even so, technological advances, new insights and understanding are needed regarding terrestrial-subsurface systems, biophysical process interactions, and feedbacks to atmospheric processes. Importantly, groundwater resources need to be assessed in the context of atmospheric CO 2 enrichment, warming trends and associated changes in intensities and frequencies of wet and dry periods, even though projections in space and time are uncertain. Potential feedbacks of groundwater on the global climate system are largely unknown, but may be stronger than previously assumed. Groundwater has been depleted in many regions, but management of subsurface storage remains an important option to meet the combined demands of agriculture, industry (particularly the energy sector), municipal and domestic water supply, and ecosystems. In many regions, groundwater is central to the water-food-energy-climate nexus. Strategic adaptation to global change must include flexible, integrated groundwater management over many decades. Adaptation itself must be adaptive over time. Further research is needed to improve our understanding of climate and groundwater interactions and to guide integrated groundwater management.

“…In addition, climate change is probably one of the most challenging pressures facing hydrological systems and water resources. Consequently, there are several researches subject to the effect of climate change on the groundwater resource such as [1], [2], [3], [4], [5], [6]. [2] investigated the impact of climate change on two small aquifers in western Canada and the United States and revealed the impact from climate change on recharge and groundwater levels at both study areas.…”

Abstract. This research investigates the impact of climate change on the hydraulic heads of Thailand's Lower Chao Phraya basin. The research also determines the sustainability of groundwater as the result from climate change. In the study, the climatic scenario (IPSL-CM5A-MR) of the Representative Concentration Pathways (RCP) between 2.6, 4.5 and 8.5 were considered, and the simulations were carried out using the three-dimensional groundwater flow model (i.e. MODFLOW-2000) predicting the groundwater behavior between 2017 and 2036. The findings revealed that the impact of climate change on the hydraulic head fluctuation was positively correlated. Specifically, under the IPSL-CM5A-MR RCP 4.5 that has the highest average precipitation, the average hydraulic head increased. In conclusion, the sustainability of groundwater in the Lower Chao Phraya basin was sufficient during the simulated time. However, the groundwater budget was lower than the average groundwater budget during 2009 -2014 indicating, the groundwater storage was continuously decreased. Specifically, the 2 nd , and 3 rd (Phra Pradeang and Nakorn Luang) aquifers may be facing the groundwater shortage in the future.
