Drought poses a serious threat to the resilience of communities and ecosystems in the U.S. USGS has developed a new coordinated and integrated drought science strategy that represents a new path forward towards understanding the complexity of drought issues, their impact on human and natural systems, and the opportunities to inform policy and decision-making for adaptation and mitigation.

USGS integrated drought science

Project Need and OverviewDrought poses a serious threat to the resilience of human communities and ecosystems in the United States (Easterling and others, 2000). Over the past several years, many regions have experienced extreme drought conditions, fueled by prolonged periods of reduced precipitation and exceptionally warm temperatures. Extreme...

Variability and trends in runoff efficiency in the conterminous United States

Variability and trends in water-year runoff efficiency (RE) — computed as the ratio of water-year runoff (streamflow per unit area) to water-year precipitation — in the conterminous United States (CONUS) are examined for the 1951 through 2012 period. Changes in RE are analyzed using runoff and precipitation data aggregated to United States...

Enhancing drought resilience with conjunctive use and managed aquifer recharge in California and Arizona

Projected longer‐term droughts and intense floods underscore the need to store more water to manage climate extremes. Here we show how depleted aquifers have been used to store water by substituting surface water use for groundwater pumpage (conjunctive use, CU) or recharging groundwater with surface water (Managed Aquifer Recharge, MAR). Unique...
