“…Due to the rapid economic growth in the past few decades, the over-exploitation of groundwater resources has constantly raised the alert. Numerous studies, most of which solely focus on the groundwater component and employ MODFLOW as their modeling tool, have been completed to analyze the NCP's hydrological system and groundwater resources utilization, such as Jia et al (2002), Foster et al (2004), Mao et al (2005), Xu et al (2005), Nakayama et al (2006), Wang (2006), Xu (2006), Liu et al (2008), Wang et al (2008), Shao et al (2009), , Lu et al (2011), Zhou et al (2012) and Cao et al (2013). Groundwater recharge in these models is oversimplified, estimated as a fraction of the precipitation without considering the dynamics of the evaporation or the existence of irrigation.…”

“…In some areas of the world groundwater levels of major aquifers are rapidly declining as an effect of unsustainable pumping and insufficient recharge. This is for instance the case in West Java, Indonesia; Dhaka, Bangladesh; and Beijing, China (Braadbaart and Braadbaart, 1997;Hoque et al, 2007;Zhou et al, 2012). Large-scale hydrological models have become increasingly popular in assisting water resources management of large aquifer systems (Casper and Vohland, 2008;Goderniaux et al, 2009;Branger et al, 2010).…”

Abstract. Groundwater overdraft has caused fast water level decline in the North China Plain (NCP) since the 1980s. Although many hydrological models have been developed for the NCP in the past few decades, most of them deal only with the groundwater component or only at local scales. In the present study, a coupled surface water-groundwater model using the MIKE SHE code has been developed for the entire alluvial plain of the NCP. All the major processes in the land phase of the hydrological cycle are considered in the integrated modeling approach. The most important parameters of the model are first identified by a sensitivity analysis process and then calibrated for the period 2000-2005. The calibrated model is validated for the period 2006-2008 against daily observations of groundwater heads. The simulation results compare well with the observations where acceptable values of root mean square error (RMSE) (most values lie below 4 m) and correlation coefficient (R) (0.36-0.97) are obtained. The simulated evapotranspiration (ET) is then compared with the remote sensing (RS)-based ET data to further validate the model simulation. The comparison result with a R 2 value of 0.93 between the monthly averaged values of simulated actual evapotranspiration (AET) and RS AET for the entire NCP shows a good performance of the model. The water balance results indicate that more than 70 % of water leaving the flow system is attributed to the ET component, of which about 0.25 % is taken from the saturated zone (SZ); about 29 % comes from pumping, including irrigation pumping and non-irrigation pumping (net pumping). Sustainable water management analysis of the NCP is conducted using the simulation results obtained from the integrated model. An effective approach to improve water use efficiency in the NCP is by reducing the actual ET, e.g. by introducing watersaving technologies and changes in cropping.

“…In these areas groundwater is mainly derived from shallow depths of not more than 100-120 m (Dou et al, 2006) compared to the deeper origin of the groundwater (N 100 m) for the tap water production in urban Beijing. In contrast to the deeper aquifers of the Beijing Plain, which consist mainly of coarse-grained sand-pebble-gravel associations (Zhou et al, 2012), the shallow alluvial sediments consistent of fine-grained sediments and clays with sulfide minerals and organic matter are suggested to contain substantial amounts of As (Plant et al, 2003). Consequently, the elevated arsenic contents in the tap water of rural Beijing are probably caused by its origin from shallow As-rich aquifers.…”

“…The Bohai Bay as part of the East China Sea lies in a distance of around 150 km to the southeast of Beijing. The two major rivers Yongding River and Chaobai River, dammed by the Guanting Reservoir west and the Miyun Reservoir northeast of Beijing City, account for 90% of the total surface water inflow to the Beijing Plain (Zhou et al, 2012).…”

The sedimentary deposits of the Quaternary layer are classified into four aquifers based on their lithological properties and hydrodynamic conditions.…”

In the present study we investigated Beijing tap water from urban and suburban areas as well as bottled water from Beijing supermarkets with a focus on selected anions (Cl − , NO 3 − , SO 4 2− , F − ), metals and trace elements (Al, As, Co, Cr, Cu, Fe, Mn, Ni, Pb, Se, V, Zn), in order to reveal the degree of anthropogenic pollution and the ability of both water types to serve as a safe drinking water source. S sulfate ) analyses on Beijing tap water for the identification of specific pollution sources. 27% of the analyzed tap water samples show one or more constituents above the national guideline limits. 9% of the samples reveal concentrations above the NO 3 − limit, while 5% exceed the standard value for As, which makes this tap water unsuitable for daily consumption due to a serious health risk, especially for children and babies. The median concentrations of most analyzed compounds are significantly higher in Beijing tap water compared to European countries. Concentration and isotope data for tap water indicate urban sewage as the major origin of anthropogenic pollutants probably released by leaking wastewater pipes to the local groundwater as the principal tap water source. The results suggest industrial emissions and As-rich alluvial deposits as further but minor pollutant sources. In contrast, bottled water exhibits exclusively concentrations below the standard values and clearly lower median values compared to Beijing tap water. Hence, bottled water can be recommended as a valuable alternative to Beijing tap water, especially in areas where the pollutant levels in tap water are high. Moreover, the results reveal the problematic groundwater situation in Beijing and demonstrate the advantages of a combined geochemical and multiple isotope approach in order to uncover complex pollution mechanisms in metropolitan areas.

Water sustainability in megacities is a growing challenge with far‐reaching effects. Addressing sustainability requires an integrated, multidisciplinary approach able to capture interactions among hydrology, population growth, and socioeconomic factors and to reflect changes due to climate variability and land use. We developed a new systems modeling framework to quantify the influence of changes in land use, crop growth, and urbanization on groundwater storage for Beijing, China. This framework was then used to understand and quantify causes of observed decreases in groundwater storage from 1993 to 2006, revealing that the expansion of Beijing's urban areas at the expense of croplands has enhanced recharge while reducing water lost to evapotranspiration, partially ameliorating groundwater declines. The results demonstrate the efficacy of such a systems approach to quantify the impacts of changes in climate and land use on water sustainability for megacities, while providing a quantitative framework to improve mitigation and adaptation strategies that can help address future water challenges.
