Effects of climate change on depression‐focused groundwater recharge in the Canadian Prairies [PDF]
Vadose Zone Journal, 2021 Small topographic depressions are ubiquitous in the glaciated terrain of the Northern Prairies characterized by a cold semiarid climate. Groundwater recharge in this region is focused in topographic depressions, which receive lateral inputs of snowmelt ...

A Coupled Soil Water Balance Model for Simulating Depression-Focused Groundwater Recharge
Vadose Zone Journal, 2018 In arid and semiarid environments, focused infiltration of rain and snowmelt water under topographic depressions is an important mechanism of groundwater recharge.

Ephemeral Ponds: Are They the Dominant Source of Depression‐Focused Groundwater Recharge? [PDF]
Water Resources Research, 2020 AbstractDepression‐focused recharge is a concept proposed to explain groundwater recharge in the prairie regions of North America. Topographic depressions in this hummocky landscape collect blowing snow and snowmelt, and occasional runoff during rainfall events.

Quantifying seasonal, depression focused recharge in the context of public supply well vulnerability
Hydrological Processes, 2023 AbstractDepression focused recharge (DFR) may be a hydrologically important process that impacts the vulnerability of public supply wells, specifically related to pathogenic contaminants. The nature of DFR in glacial moraine environments, such as those located in northern latitudes within North America and Europe, is less well established than in other

Water Resources Research, 2004 In the northern prairie region of North America, numerous seasonal wetlands and ephemeral ponds form as snowmelt water is trapped in small topographical depressions. A detailed hydrogeological investigation is combined with electrical resistivity imaging (ERI) to evaluate the roles of the wetlands and ponds on depression‐focused groundwater recharge at

Sensors, 2021 In semi-arid ecoregions of temperate zones, focused snowmelt water infiltration in topographic depressions is a key, but imperfectly understood, groundwater recharge mechanism. Routine monitoring is precluded by the abundance of depressions. We have used

Effects of preferential flow on snowmelt partitioning and groundwater recharge in frozen soils [PDF]
Hydrology and Earth System Sciences, 2019 Snowmelt is a major source of groundwater recharge in cold regions. Throughout many landscapes snowmelt occurs when the ground is still frozen; thus frozen soil processes play an important role in snowmelt routing, and, by extension, the timing and ...

Runoff and focused groundwater-recharge response to flooding rains in the arid zone of Australia
Hydrogeology Journal, 2021 A groundwater recharge investigation in the arid zone of Australia is presented. The investigation used a wide range of hydrogeological techniques including geological mapping, surface and borehole geophysics, groundwater hydraulics, streambed ...
