“…They found that although evapotranspiration should be higher during the monsoonal summer, recharge occurred primarily during this season, likely due to thin soil cover that permits rapid infiltration to highly permeable bedrock. Gleeson et al (2009) investigated and confirmed that recharge was controlled by fracture networks and soil thickness in a fractured crystalline aquifer using evidence that included 2 H from snowmelt and groundwater samples. Finally, Praamsma et al (2009) used the stable isotopes of water to track the groundwater flow path in a shallow bedrock setting.…”

“…Numerous other studies have used stable isotopes to explore recharge dynamics, specifically in fractured bedrock (Lee et al, 1999;Gleeson et al, 2009;Praamsma et al, 2009). Lee et al (1999) analyzed the δ 18 O and δ 2 H composition of precipitation, groundwater, and surface water in order to determine the relative contribution of rainy and dry season precipitation to recharge in Korea.…”

The response of a fractured bedrock aquifer in a temperate region (Gulf Islands, British Columbia) to heavy rainfall events is characterized. Of the 14 provincial observation wells with hourly groundwater level data, wells with shallow water levels showed pronounced responses to heavy rain events, a lag less than 12 hours, and a strong correlation to all rain events. Rises in groundwater level at Well 125 appear to be better related to all rain events than exclusively heavy rain during summer, and decrease as the rainfall intensity increases. Thermal infrared images and δ 18 O and δ 2 H composition for precipitation and seepage indicate an increase in seepage in the late fall and winter.Solution of the Green-Ampt equation for rainfall events of varying magnitude suggest that an increase in winter rainfall intensity leads to more surface ponding and overland flow. The projected occurrence of more heavy rain events in the future may result in lower net recharge.

Groundwater recharged by meteoric water supports human life by providing two billion people with drinking water and by supplying 40% of cropland irrigation. While annual groundwater recharge rates are reported in many studies, fewer studies have explicitly quantified intra-annual (i.e., seasonal) differences in groundwater recharge. Understanding seasonal differences in the fraction of precipitation that recharges aquifers is important for predicting annual recharge groundwater rates under changing seasonal precipitation and evapotranspiration regimes in a warming climate, for accurately interpreting isotopic proxies in paleoclimate records, and for understanding linkages between ecosystem productivity and groundwater recharge. Here we determine seasonal differences in the groundwater recharge ratio, defined here as the ratio of groundwater recharge to precipitation, at 54 globally distributed locations on the basis of 18 O/ 16 O and 2 H/ 1 H ratios in precipitation and groundwater. Our analysis shows that arid and temperate climates have wintertime groundwater recharge ratios that are consistently higher than summertime groundwater recharge ratios, while tropical groundwater recharge ratios are at a maximum during the wet season. The isotope-based recharge ratio seasonality is consistent with monthly outputs from a global hydrological model (PCR-GLOBWB) for most, but not all locations. The pronounced seasonality in groundwater recharge ratios shown in this study signifies that, from the point of view of predicting future groundwater recharge rates, a unit change in winter (temperate and arid regions) or wet season (tropics) precipitation will result in a greater change to the annual groundwater recharge rate than the same unit change to summer or dry season precipitation.
