Transitions from irrigated to dryland agriculture in the Ogallala Aquifer: Land use suitability and regional economic impacts

Many agricultural communities depend on groundwater irrigation as a supplemental or primary water source. However, groundwater resources are finite, and depletion can make continued irrigation inviable. When modeling the economic impacts of future …

Adding our leaves: A community-wide perspective on research directions in ecohydrology

Integrating the water planetary boundary with water management from local to global scales

The planetary boundaries framework defines the ‘safe operating space for humanity' represented by nine global processes which can destabilize the Earth System if perturbed. The water planetary boundary attempts to provide a global limit to …

Illuminating water cycle modifications and Earth System resilience in the Anthropocene

Fresh water – the bloodstream of the biosphere – is at the centre of the planetary drama of the Anthropocene. Water fluxes and stores regulate the Earth's climate and are essential for thriving aquatic and terrestrial ecosystems, as well as water, …

The evolution of virtual water flows in China's electricity transmission network and its driving forces

Long-distance electricity transmissions could transfer water stress associated with electric power generation from the consumption side to the production side. In China, the rapidly growing scale of west-to-east electricity transmission is …

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 …

Comparing the effects of climate and land use on surface water quality using future watershed scenarios

Eutrophication of freshwaters occurs in watersheds with excessive pollution of phosphorus (P). Factors that affect P cycling and transport, including climate and land use, are changing rapidly and can have legacy effects, making future freshwater …

Combining Evapotranspiration and Soil Apparent Electrical Conductivity Mapping to Identify Potential Precision Irrigation Benefits

Precision irrigation optimizes the spatiotemporal application of water using evapotranspiration (ET) maps to assess water stress or soil apparent electrical conductivity (ECa) maps as a proxy for plant available water content. However, ET and ECa …

Management of minimum lake levels and impacts on flood mitigation: A case study of the Yahara Watershed, Wisconsin, USA

Lake level regulation is commonly used to manage water resources and mitigate flood risk in watersheds with linked river-lake systems. In this study, we first assess exposure, in terms of both population and land area, to flooding impacts in the …

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 …
