“…Notably, differences in seasonal recharge estimates were as large as 28% depending on year and site, with overestimations occurring in the cold season and underestimations during the warm season. These findings become increasingly valuable when seasonal groundwater recharge is of great importance (Liu et al., 2021; Mollema & Antonellini, 2013; Zhang et al., 2019). The results also show that given groundwater recession rates change over seasons; therefore, it may be more appropriate to call them recession time coefficients.…”

Groundwater is a vital resource for both natural ecosystems and humans (Wada et al., 2014). Over 2 billion people rely on groundwater as their main freshwater resource (Famiglietti, 2014). Groundwater is also extensively used in irrigated agriculture (Siebert et al., 2010). The increased water extraction to satisfy human needs has led to groundwater depletion in many parts of the world (Aeschbach-Hertig & Gleeson, 2012;Rodell et al., 2009;Scanlon et al., 2007). Given these evolving challenges, which are expected to get worse with increasing population, assessment of groundwater recharge, that is, the amount of water that replenishes aquifers after escaping the vadose zone , is crucial for sustainable management and development of groundwater resources (Moon et al., 2004). Groundwater recharge is, however, an inherently complex process controlled by multiple factors including climate, geomorphology, vegetation characteristics and antecedent soil moisture conditions, among others (De Vries & Simmers, 2002). Several methods to obtain estimates of groundwater recharge exist, including those based on direct measurements (Flint et al., 2002) and indirect methods that often use empirical models (Reitz & Sanford, 2020), physically based land surface models (

“…The maximum terrain rise (d) is about 250 m according to Digital Elevation Models (DEM) of the Ordos Plateau. Additionally, the recharge rate (W) as 1.23×10 −5 m/d was calculated based on the precipitation amount (300 mm/a) multiplied by the average precipitation recharge coefficient of 0.15 (Yin et al 2010;Zhang et al 2019). With these numerical values, the calculation result of ∆h/d is determined to be 14.8 for a specific value of m, namely 8.…”

“…There is a hypothesis of groundwater flow systems in the lake-concentrated regions ( Figure 1c): It also develops hierarchically nested groundwater flow systems that include local, intermediate and regional flow systems under the control of the groundwater-fed lakes as discharge areas, as shown in Figure 2a [24,25]. The local flow system usually occurs between groundwater divides and neighboring lakes (e.g., Dake Lake and Mukai Lake) with a relatively shallow circulation depth, while, intermediate and regional flow systems are present between the major divides and the relatively larger lakes such as HTCH Lake, with significantly deeper circulation depths and longer flow distances relative to local flow systems.…”

The lowest reaches of a large-scale basin could be the discharge areas of local, intermediate and regional groundwater flow systems with significantly distinct travel distances and travel times. This study aims to delineate the groundwater chemical characteristics and the mechanism controlling the chemical evolution in the lowest reaches of the Wushenzhao Cretaceous basin, NW China. A total of 38 groundwater samples were collected and were chemically classified into five distinct water types by means of a Piper Plot. According to the hydrogeological setting and groundwater age, the spatial distribution of these water types is found to be associated with hierarchically nested groundwater flow systems (local and regional system): Types 1, 2, 3 and 4 belong to the local groundwater flow system, while type 5 belongs to the regional flow system. Graphical plots, stable isotopes and geochemical modeling techniques were used to interpret the observed compositions. The results show the dominance of carbonate and gypsum dissolution in type 1 waters; ion exchange in types 2, 3 and 4; and evaporite dissolution in type 5. In addition, human activities in the form of extensive irrigation also affect the chemical compositions of type 1 water. These findings are important for the sustainable management of groundwater resources in the study area.
