Effects of climate change on depression‐focused groundwater recharge in the Canadian Prairies [PDF]
Vadose Zone Journal, 2021 Abstract 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 runoff in addition to vertical inputs of ...

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

A Coupled Soil Water Balance Model for Simulating Depression‐Focused Groundwater Recharge
Vadose Zone Journal, 2018 Core Ideas Ephemeral ponds in depressions are the foci of groundwater recharge in the Canadian Prairies. Freeze–thaw processes influence snowmelt runoff and ...

The Canadian Prairies is characterized by a cold, semiarid climate with topographical variations containing numerous depressions. These depressions play an important role in the hydrology of the prairie region by storing runoff water and replenishing groundwater through focused infiltration termed as depression-focused groundwater recharge.

Abstract The Oak Ridges Moraine (ORM) is a key hydrogeologic feature in southern Ontario. Previous work has emphasized the value of groundwater recharge (R) estimates and information on the timing and location of R to incorporating groundwater protection into land-use planning on the ORM, and has suggested that ponding and depression-focused recharge

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

AbstractThe Oak Ridges Moraine (ORM) is a key hydrogeologic feature in southern Ontario. Previous research has emphasized the importance of depression‐focused recharge (DFR) for the timing and location of water recharge to the ORM's aquifers. However, the significance of DFR has not been empirically demonstrated, and the ORM's permeable surficial ...

Field‐Scale Preferential Transport of Water and Chloride Tracer by Depression‐Focused Recharge
Journal of Environmental Quality, 2001ABSTRACTA tracer study was initiated in November 1993 to investigate depression‐focused recharge and to monitor solute movement through the vadose zone into the shallow ground water in southeastern North Dakota. Granular potassium chloride (KCl) was surface‐applied to two areas overlying subsurface drains and to one area instrumented with soil solution
