Flooding is a major natural hazard which every year impacts different regions across the world. Between 2000 and 2008, various types of natural hazards, mainly floods have affected the largest number of people worldwide, averaging 99 million people per year (WDR, 2010). In the U...

This draft report investigates the issues and challenges associated with identifying, calculating, and mapping indicators of the relative vulnerability of water quality and aquatic ecosystems, across the United States, to the potential impacts of global change. Using a large set...

During the past decades, U.S. Environmental Protection Agency (EPA), U.S. Department of Agriculture (USDA) and other Federal program administrative and regulatory agencies spent considerable amounts of time and money to manage risks to surface waters associated with agricultural ...

The APWES is a place-based study for the U.S. EPA Ecosystem Services Research Program conducted through the collaboration across the EPA Office of Research and Development. The mission of the APWES is to develop ecosystem services science to inform watershed and coastal manageme...

This EPA report will illustrate the application of different climate assessment capabilities within EPA’s BASINS modeling system for assessing a range of potential questions about the effects of climate change on streamflow and water quality in different watershed settings and us...

Hydromodification activities are driven by human population growth and resource extraction and consumption including urbanization, agriculture, forestry, mining, water withdrawal, climate change, and flow regulation by dams and impoundments. These anthropogenic activities alter n...

The Ecosystem Services Research Program (ESRP) is a new, multi-year research initiative under development by the U.S. Environmental Protection Agency (EPA). The overall goal of the ESRP is to transform the way decision-makers understand and respond to environmental issues, making...
