Advancing Water Security and Environmental Sustainability Through Evaluation of Water Use From the Field to State-Wide Scale
The United States (US) has experienced a surge in water shortages and droughts in recent times. Water shortages can result from population growth, climate change, inadequate water management policies, and the improper use of available technologies. The existing data and research on water use …

Statistically Evaluating Water Consumption Historically and Across Multiple Users in Virginia
This study explores key aspects of water usage in Virginia via a broad-scale analysis of multiple water users through thirty years of time-series records from the Virginia Water Use Data System. A full spectrum of users is considered, including water used for energy, industrial, agricultural and …

Toward joint water-power electric grid modeling
The water-energy nexus refers to the relationship between how much water is used to generate and transmit energy, and how much energy it takes to collect, clean, move, store, and dispose of water. The dependence of the electric power grid on water varies based on generation technology (i.e., prime …

Estimating hydrologic fluxes, crop water use, and agricultural land use in China from multiple data sources
… (Ramankutty et al., 2008) and by altering the water cycle through both co-opting rainfall and surface water withdrawals (Postel et al., 1996). As the world's population continues to grow and individual diets become more resource-intensive, the demand for food - and the land and water necessary …

Understanding Streamflow Change at the Scale of a Major City: Chicago
… observed in urban, suburban and agricultural watersheds in and around the Greater Chicago area. A novel statistical method, the Procedure for Change Pattern and Signi ficance (PCPS), is developed to detect non-stationarity and identify the timing and duration of these shifts in hydrologic …

Avoided Water Cost of Electricity Generation for Solar PV and Wind Technologies in Southern California
… is to provide a foundation for evaluating the water costs associated with electricity production to calculate the avoided water cost of energy for solar PV and wind technologies relative to coal, natural gas, nuclear, geothermal, concentrated solar thermal, and biomass. Water consumption is …

Water footprint of electric power generation : modeling its use and analyzing options for a water-scarce future
The interdependency between water and energy, sometimes called the water-energy nexus, is growing in importance as demand for both water and energy increases. Energy is required for water treatment and supply, while virtually all processes for energy production require significant amounts of water. …

Disturbance Related Patterns in Fish Community Structure and Function in River Systems of the Lower Athabasca Oil Sands Region, Alberta
Anthropogenic development is altering watersheds and threatening freshwater ecosystems and the resources therein. Direct impacts of industry including conversion of land cover and increased water withdrawals from rivers, compounded with indirect influences such as climate change, collectively …

The resource demands and water stress of cities: A study of the U.S. urban food-energy-water nexus
… for commodities such as food, energy, and water in cities. Energy and food production depend on water resources, and piped treated water and wastewater systems depend on energy resources, representing aspects of the food-energy-water nexus. Because water resources are used outside of cities …

Fair allocation and trading of surface water rights under the Riparian Doctrine
One key water resource challenge that faces the eastern United States today is how to regulate water withdrawals by offstream users, while preserving the fair sharing philosophy of the common-law Riparian Doctrine. Traditionally, this doctrine requires that riparians (users owning land adjacent to …

Frameworks for estimating virtual water flows among U.S. states
<p>The United States is the world's top virtual water exporting nation, but not much is known about the country's internal virtual water flow patterns and the volumes involved. Previous studies have suggested that the import of virtual water, defined as the volume of water required to produce a …

Human mediated physical and virtual water transfers of the United States: Who uses the water?
… connections between consumers and distant water resources used in production, by enabling consumer demand in one location to be fulfilled with production and resource use in another. Many of the environmental consequences associated with water-intensive production, particularly agricultural …

A multi-scale, hierarchical approach to map the location and condition of riparian zones in the southern Rockies ecoregion
… associated with climate change and additional water withdrawals due to population growth particularly in the western United States and other arid regions. Consequently, it is imperative to understand the current location and extent of riparian zones. Although many agencies and organizations are …

Modeling the Food-Water Nexus: A Spatio-temporal Accounting of Agricultural Land and Water Use in the United States
Agriculture dominates both land and water use in the United States, and plays a pivotal role in both national food security and global agricultural trade. Yet, this critical system faces growing pressures from groundwater depletion, climate change, and competing demands for water across sectors. …
