Stream-Aquifer Interactions

Cannabis and residential groundwater pumping impacts on streamflow and ecosystems in Northern California

Cannabis is an emerging agricultural frontier, but due to its quasi-legal status its environmental impacts are poorly understood. Where cannabis is irrigated by groundwater, pumping can lead to streamflow depletion in surrounding streams which may …

Rapid and accurate estimates of streamflow depletion caused by groundwater pumping using analytical depletion functions

Reductions in streamflow due to groundwater pumping (streamflow depletion) can negatively impact water users and aquatic ecosystems but are challenging to estimate due to the time and expertise required to develop numerical models often used for …

Groundwater controls on post-fire permafrost thaw: Water and energy balance effects

Fire frequency and severity are increasing in high-latitude regions, but the degree to which groundwater flow impacts the response of permafrost to fire remains poorly understood. Here we use the Anaktuvuk River Fire (Alaska, USA) as an example for …

Groundwater pumping impacts on real stream networks: Testing the performance of simple management tools

Quantifying reductions in streamflow due to groundwater pumping (‘streamflow depletion') is essential for conjunctive management of groundwater and surface water resources. Analytical models are widely used to estimate streamflow depletion but …

Changing groundwater discharge dynamics in permafrost regions

Permafrost thaw due to climate warming modifies hydrological processes by increasing hydrological connectivity between aquifers and surface water bodies and increasing groundwater storage. While previous studies have documented arctic river baseflow …

Does hillslope trenching enhance groundwater recharge and baseflow in the Peruvian Andes?

As Andean glaciers rapidly retreat due to climate change, the balance of groundwater and glacial meltwater contributions to stream discharge in tropical, proglacial watersheds will change, potentially increasing vulnerability of water resources. The …
