Stream-Aquifer Interactions

Modeling Assessment of Aquifer Contamination by Sulfate and Uranium in the Upper Arkansas River Corridor in Kansas

Groundwater in the upper Arkansas River corridor has been contaminated by elevated concentrations of dissolved solids in Arkansas River water. Most of the dissolved solids originate from the soils and bedrock in eastern Colorado, where river water is …

Potential Impacts of Groundwater Pumping on Stream Temperature Are Greatest in Streams With Substantial Cold Groundwater Inflows

Groundwater pumping-induced reductions in streamflow (known as 'streamflow depletion') have been documented worldwide, but potential impacts of streamflow depletion on water quality indicators like stream temperature are not well understood. Here, we …

Lagged streamflow depletion due to pumping-induced stream drying: Incorporation into analytical streamflow depletion estimation methods

Water management often requires accounting for reductions in streamflow caused by groundwater pumping (‘streamflow depletion’). Since streamflow depletion cannot be quantified from observational data, it is typically modeled. Analytical depletion …

Using values-informed mental models to understand farmer, water manager, and scientist use and perceptions of hydrologic models

Decision-support systems using environmental data and models are increasingly common, but not always adopted by the intended end-users. This disconnect may be partly due to different values related to nature and the scientific process. In this study, …

STICr: An open-source package and workflow for stream temperature, intermittency, and conductivity (STIC) data

Non-perennial streams constitute over half the world's stream miles but are not commonly included in streamflow monitoring networks. As a result, Stream Temperature, Intermittency, and Conductivity (STIC) loggers are widely used for characterizing …

Current trends and biases in groundwater modelling using the community-driven groundwater model portal (GroMoPo)

Using national hydrologic models to obtain regional climate change impacts on streamflow basins with unrepresented processes

Climate change is increasingly impacting water availability. National-scale hydrologic models simulate streamflow resulting from many important processes, but often without processes such as human water use and management activities. This work …

Biogeochemical and community ecology responses to the wetting of non-perennial streams

Transitions between dry and wet hydrologic states are the defining characteristic of non-perennial rivers and streams, which constitute the majority of the global river network. Although past work has focused on stream drying characteristics, there …

Streamflow Depletion Caused by Groundwater Pumping: Fundamental Research Priorities for Management-Relevant Science

Reductions in streamflow caused by groundwater pumping, known as streamflow depletion, link the hydrologic process of stream-aquifer interactions to human modifications of the water cycle. Isolating the impacts of groundwater pumping on streamflow is …

Exploring drivers of groundwater recharge at Konza Prairie (Flint Hills region, Kansas, USA) using transfer function noise models

Intermittent streams, which lack continuous surface water flow throughout the year, constitute a large proportion of global waterways and influence downstream water quality and quantity. Stream intermittency has been increasing in the Great Plains …
