“…It thus provided a more realistic picture of the groundwater recharge process, taking into account the position of the groundwater level in every time step, than previous studies [9][10][11][12][13][14][15][16]44]. Understanding and information on this process are important for sustainable water resource management and vulnerability assessments in low-lying aquifers.…”

“…A number of recent studies have assessed the impact of climate change on groundwater using groundwater flow modelling as an assessment tool, and have found that recharge estimation is one of the most challenging parts of groundwater modelling [9][10][11][12][13][14][15][16]. Many previous studies have linked the results of recharge models to groundwater flow models in a one-way approach in which time-dependent recharge is calculated first, basically for different soil columns where hydraulic permeability of soil and average groundwater level are known.…”

Abstract:The impact of climate change and Baltic Sea level rise on groundwater resources in a shallow, unconfined, low-lying coastal aquifer in Hanko, southern Finland, was assessed using the UZF1 model package coupled with the three-dimensional groundwater flow model MODFLOW to simulate flow from the unsaturated zone through the aquifer. The snow and PET models were used to calculate the surface water availability for infiltration from the precipitation data used in UZF1. Infiltration rate, flow in the unsaturated zone and groundwater recharge were then simulated using UZF1. The simulation data from climate and sea level rise scenarios were compared with present data. The results indicated changes in recharge pattern during 2071-2100, with recharge occurring earlier in winter and early spring. The seasonal impacts of climate change on groundwater recharge were more significant, with surface overflow resulting in flooding during winter and early spring and drought during summer. Rising sea level would cause some parts of the aquifer to be under sea level, compromising groundwater quality due to intrusion of sea water. This, together with increased groundwater recharge, would raise groundwater levels and consequently contribute more surface leakage and potential flooding in the low-lying aquifer.

“…In this paper, the sliding average method and the Mann-Kendall test method have been adopted to analyze the annual variations of climatic factors [14], such as precipitation, temperature, and land evaporation [15,16]. The purpose of this study is to reveal the influence of atmospheric precipitation and Fenhe River leakage on karst groundwater recharge in the spring region and to provide a scientific basis for the reasonable exploitation and utilization of karst groundwater resources in the spring region and the establishment of karst groundwater management and protection policies [17,18].…”

Due to climate change and human activities over the last fifty years, the spring flow volume of karst groundwater has sharply diminished in China. Climate change is one of the critical factors that initiates a series of karst hydrogeologic and water ecological environmental problems, because the precipitation shows a decreasing trend while the temperature shows an increasing trend. The Jinci Spring is one of the largest, most famous springs in northern China. This study employed data from the Taiyuan Meteorological Station and ten precipitation stations in and around the Jinci Spring region as well as the runoff data gathered from two hydrological monitoring stations during 1960-2012. The sliding average method and the Mann-Kendall test were used to analyze the variation tendency of precipitation, temperature, and land evaporation in this area. Finally, the following were calculated: the varying pattern of the karst groundwater recharge amount and the response of the recharge amount to precipitation, land evaporation, and river runoff by quantitative analysis. The results indicated that the precipitation and land evaporation amount decreased at first and then subsequently increased. Likewise, the variation trend of the karst groundwater recharge amount in the spring region was roughly consistent with the precipitation variation pattern. In contrast, the temperature displayed an increasing trend. The climate change resulted in a reduction of the karst groundwater recharge amount, and it had the greatest influence in the 1990s, which caused the karst groundwater recharge amount to decrease 26.75 mm as compared to that of the 1960s (about 39.68% lower than that of the 1960s). The Jinci Spring had zero flow during this period. The reduction in precipitation was one of main factors that caused the cutoff of the Jinci Spring.

“…The future impacts of climate change on dryland cropping systems have been widely studied in different agricultural regions (Thomas 2008, Xiao et al 2010, Ö zdogan 2011, Gohari et al 2013, Sommer et al 2013, including Australia (Ludwig and Asseng 2006, Anwar et al 2007, Luo et al 2009, Asseng et al 2011, Barlow et al 2013. Countries with Mediterraneantype climates, particularly semiarid regions like the grain belt of southwestern Australia, appear to be most vulnerable to climate change and the subsequent reduction in water resources (Ali et al 2012, Silberstein et al 2012. Although the overall frequency of frost events is likely to decrease with rising temperature, drier atmospheric conditions may result in radiative frosts earlier in the growing season (Zheng et al 2012).…”
