“…Sustainable groundwater management has also been addressed in cold and humid climates where GR is often considered to be abundant and non-limiting (i.e., Dripps et al 2007;Rivard et al 2014;Boumaiza et al 2020). However, even when water is abundant overall, increased temperatures due to climate change may trigger increased evapotranspiration rates during the summer when water needs are the greatest (e.g., agriculture and recreational activities) and this can have large impacts on groundwater renewal rates (Turkeltaub et al 2015;Saha et al 2017;Guerrero-Morales et al 2020).…”

Groundwater recharge (GR) is a complex process that is difficult to quantify. Increasing attention has been given to unsaturated zone modeling to estimate GR and better understand the processes controlling it. Continuous soil-moisture time series have been shown to provide valuable information in this regard. The objectives of this study were to (i) analyze the processes and factors controlling GR in an unconfined granular aquifer in a cold and humid environment and (ii) assess the uncertainties associated with the use of data from different sources. Soil moisture data monitored over three years at three experimental sites in southern Quebec (Canada) were used to calibrate the HYDRUS-1D model and to estimate ranges of possible GR in a region where groundwater is increasingly used as a source of fresh water. The simulations identified and quantified important factors responsible for the near-surface water balance that leads to GR. The resulting GR estimates from 2016 to 2018 showed marked differences between the three sites, with values ranging from 347 to 735 mm/y. Mean GR for the three sites was 517 mm/y for 2016–2018 and 455 mm/y for the previous 12-year period. GR was shown to depend on monthly variations in precipitation and on soil textural parameters in the root zone, both controlling soil-water retention and evapotranspiration. Monthly recharge patterns showed distinct preferential GR periods during the spring snowmelt (38–45% of precipitation) and in the fall (29% of precipitation). The use of different meteorological datasets was shown to influence the GR estimates.

“…The impact of human activities on the water resource system is more obvious in arid and semi-arid areas, such as in river diversion by damming [7] water diversion irrigation [8], GW overdraft [9] and water quality deterioration [10], which change the original SW-GW interaction mode and decrease their exchange in some basins. Saha et al [11] studied the dynamics of SW-GW interactions under the impact of climate change based on the temporal average contribution of GW to SW. Their results show that these contributions vary monthly, seasonally and annually due to precipitation variations. Based on long-term observation data, Wang et al [12] deduced the strong impacts of climate change and human activities on the GW system and basin base flow.…”

The interaction of surface water (SW) and groundwater (GW) is becoming more and more complex under the effects of climate change and human activity. It is of great significance to fully understand the characteristics of regional SW–GW circulation to reveal the water circulation system and the effect of its evolution mechanism to improve the rational allocation of water resources, especially in arid and semi-arid areas. In this paper, Yinchuan Plain is selected as the study area, where the SW–GW interaction is intensive. Three typical profiles are selected to build two-dimensional hydrogeological structure models, using an integrated approach involving field investigation, numerical simulation, hydrogeochemistry and isotope analysis. The SW–GW transformation characteristics are analyzed with these models, showing that geological structure controls the SW–GW interaction in Yinchuan Plain. The SW–GW flow system presents a multi-level nested system including local, intermediate and regional flow systems. The runoff intensity and renewal rate of different flow systems are evidently different, motivating evolution of the hydro-chemical field; human activities (well mining, agricultural irrigation, ditch drainage, etc.) change the local water flow system with a certain impacting width and depth, resulting in a variation of the hydrological and hydro-chemical fields. This study presents the efficacy of an integrated approach combining numerical simulation, hydrogeochemistry and isotope data, as well as an analysis for the determination of GW-SW interactions in Yinchuan Plain.

“…Employing physically based hydrological modeling approaches taking into consideration both surface and subsurface processes in order to project the climate change impacts on surface-groundwater interactions has not been well documented as of yet. To that respect, a few studies have investigated the interconnection between a groundwater system and a river network under a changing climate (Goderniaux et al, 2011(Goderniaux et al, , 2015; P. Goderniaux et al, 2009;Saha et al, 2017;Scibek et al, 2007). Moreover, a few works have explored the response of groundwater-dependent ecosystems, including wetlands, lakes, and riparian areas to climate change scenarios (Dwire et al, 2017;Havril et al, 2017;Klove et al, 2014;Taviani & Henriksen, 2015;van Engelenburg et al, 2018).…”

“…Thus, a spatiotemporal analysis of the climate change scenario on the surface‐groundwater interactions represented by the gaining/losing streams in relation to their adjoining groundwater domain was not conducted. Notwithstanding the previous studies, Saha et al (2017) explored the groundwater discharge/baseflow generated from gaining reaches under climate change scenarios A2 and B1 of SRES using a physically based and distributed model, that is, Gridded Surface Subsurface Hydrologic Analysis (GSSHA). Although the baseflow, supplied by the gaining streams, was projected for 2020–2040 for different temporal scales, the spatial variability of this water component across the Kiskatinaw River Watershed in British Columbia, Canada, was not evaluated.…”

Projections of potential impacts of climate change and groundwater abstraction on gaining and losing streams, particularly in ephemeral river basins exhibiting sporadic and intricate flux exchanges, have remained largely unexplored. To fill this gap, we propose a promising modeling scheme based on the new fully integrated hydrological model SWAT-MODFLOW-NWT, calibrated and validated for 1978-2012, to quantify the intertwined surface-groundwater interactions under a conjuncture of three climatic emission scenarios (RCP 2.6, 4.5 and 8.5) and two groundwater pumping variants: "pumping" (extending current groundwater utilization into the future) and "nonpumping" (assuming a complete cease of pumping in the future). By forcing the integrated model with future downscaled climate predictors of CanESM2 under the aforementioned RCPs for three time slices up to year 2100, projections of various water resources components for the Gharehsoo River Basin (GRB), in northwestern Iran were made. Results demonstrate that because of a general decrease of future precipitation, though with ups and downs across the total projection period, most of the surface and-subsurface budget quantities and fluxes are substantially affected. In particular, future groundwater discharge (baseflow) to the gaining streams will be more influenced by the "pumping" variant (increasing and decreasing for "nonpumping" and "pumping", respectively) than the concentrated groundwater recharge from the losing streams (decreasing and increasing for "nonpumping" and "pumping", respectively). Future water yield and groundwater storage will also diminish and, surprisingly, this cannot be alleviated by future "nonpumping", indicating the groundwater overutilization is the compelling reason for the future water scarcity in the GRB, rather than climate change alone. Plain Language Summary Understanding climate change impacts on surface-groundwater interactions, accommodating nearly all of water resources components of a watershed, is of paramount importance in devising effective strategies to alleviate the adverse impacts of climate change. This is particularly important in semiarid regions where the surface water scarcity has markedly increased the dependency on groundwater resources which, in turn, has highly affected the interaction between these two. We have provided an innovative scheme to assess and project climate change impacts on water resources of a basin and, in particularly, on gaining and losing streams at different temporal and spatial scales. In addition, the net impacts of climate change impacts on the quantity of the water resources, compared with the groundwater overutilization, can be quantified using the proposed methodological approach. Our findings importantly highlight that the groundwater overutilization is the major reason, rather than climate change impacts, for extreme groundwater storage depletion in the Gharehsoo River Basin, in northwestern Iran. As a result, groundwater discharge to the river network will diminish tremendously under the...
