“…The annual precipitation and potential evaporation are approximately 600 mm and 1,800 mm, respectively (M. Zhang et al, ). Because Beijing is the capital of China, many studies have been conducted by Chinese government (Y. Zhang et al, ; Zhou et al, ; Zhu et al, ), including the continuous monitoring of the groundwater level, and evaluating the sustainability of water resources development.…”

Due to coarse spatial resolution, the application of Gravity Recovery and Climate Experiment (GRACE) data in local groundwater resource management has been limited. To overcome this issue, a downscaling approach is presented to improve the spatial resolution of GRACE‐derived groundwater storage anomalies using evapotranspiration (ET) data. The statistical downscaling method is only applied in areas where there is a strong relationship between GRACE‐derived groundwater storage (GWS) and ET, and the relationship can be established under different spatial resolutions. In this study, GWS anomalies are downscaled from 110 km to 2 km in the North China Plain, capturing subgrid heterogeneity in groundwater storage changes. The downscaled results are further validated using data from 111 observation wells from 2003 to 2014 in the Beijing Plain. The results show that the in situ groundwater levels agree with the Gravity Recovery and Climate Experiment (GRACE) downscaled results for the Beijing Plain in both interannual and monthly scales, with the correlation coefficient of 0.94 and 0.80, respectively. The correlation coefficients vary from 0.63 to 0.78, in 10 of the 13 Beijing Plain administrative regions. The regional downscaling approach employed in this study may be readily integrated into local water resources planning activities.

“…The ultimate configuration of the monitoring network aims to determine the key hydraulic characteristics of the groundwater flow systems (Heath, 1976;Hudak and Loaiciga, 1993;Zhou et al, 2013), which are based on the parameter estimations using monitoring materials (Loaiciga, 1989). Nevertheless, the interpretation of the monitoring data, which targets the understanding of surface-groundwater interactions under induced filtration (e.g., riverbed clogging processes), remains a challenge due to the non-steady-state flow conditions under RBF.…”

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.

“…Over abstraction manifests itself through declining groundwater levels in many major aquifers globally, with a typical range of 0.5 to 5 m/yr (Guru et al, 2000;Khater, 2002;Bajjali and Al-Hadidi, 2005;Elmore et al, 2006;Khair et al, 2010;Gaur et al, 2011;Zhou et al, 2013). This can be briefly illustrated by a few examples.…”

“…Elmore et al (2006) noted a decline in groundwater level between 0.5 and 5 m/yr in the Owens Valley, Eastern California. Significant decline in groundwater levels in the Beijing Plain, China has been observed since the 1970s, with a total drop in groundwater of more than 20 m (Zhou et al, 2013). Prakash and Ballabh (2004) observed that in Northern Gujarat, in the west part of India, the water table declined by 2.5m/yr since 1960.…”

“…Consequently, a continuous decline of groundwater levels has been observed in many countries in the past half century (Bajjali and Al-Hadidi, 2005;Gaur et al, 2011;Zhou et al, 2013). The overexploitation of renewable and non-renewable aquifers for both urban use and irrigation frequently results in a reduction of groundwater availability and quality (FAO, 2003;Goode et al, 2013).…”
