Hydrology : Expert Reports

The division produces 60-70 reports per year. These reports are unique, authoritative expert evaluations. Each report is produced by a committee of experts selected by the Academy to address a particular statement of task and is subject to a rigorous, independent peer review. The experts who volunteer their time participating on study committees are vetted to make sure that the committee has the range of expertise needed to address the task, that they have a balance of perspectives, and to identify and eliminate members with conflicts of interest. All reports undergo a rigorous, independent peer review to assure that the statement of task has been addressed, that conclusions are adequately supported, and that all important issues raised by the reviewers are addressed. Thus, while the reports represent views of the committee, they also are endorsed by the Academy.

Himalayan Glaciers: Climate Change, Water Resources, and Water Security (2012)

Scientific evidence shows that most glaciers in South Asia's Hindu Kush Himalayan region are retreating, but the consequences for the region's water supply are unclear, this report finds. The Hindu Kush Himalayan region is the location of several of Asia’s great river systems, which provide water for drinking, irrigation, and other uses for about 1.5 billion people. Recent studies show that at lower elevations, glacial retreat is unlikely t... More >>

Challenges and Opportunities in the Hydrologic Sciences (2012)

New research opportunities to advance hydrologic sciences promise a better understanding of the role of water in the Earth system that could help improve human welfare and the health of the environment. Reaching this understanding will require both exploratory research to better understand how the natural environment functions, and problem-driven research, to meet needs such as flood protection, supply of drinking water, irrigation, and wate...

Global Change and Extreme Hydrology: Testing Conventional Wisdom (2011)

As climate change warms the atmosphere, Earth's hydrology is shifting—with the potential to make floods and droughts more extreme. There is now a pressing need for decision-makers to better understand the ongoing changes in hydrologic extremes in order to make preparations for changing conditions. This report assesses changes in the frequency and severity of floods and droughts, abilities of communities to understand and forecast these changes... More >>

Review of the St. Johns River Water Supply Impact Study: Report 2 (2009)

The St. Johns River Water Management District in east-central Florida is weighing potential effects on wetland ecosystems of a proposed withdrawal of 262 million gallons of water per day from the river for future public water supply. The District's Water Supply Impact Study draws on data and analyses from seven scientific workgroups: hydrology/hydrodynamics, wetlands, biogeochemistry, plankton, benthos, submersed aquatic vegetation, and fish. Th... More >>

Mapping the Zone: Improving Flood Map Accuracy (2009)

Flooding is the leading cause of natural disaster in the United States. High-quality, digital mapping is essential to communicating flood hazards to those at risk, setting appropriate insurance rates, and regulating development in flood-prone areas. As the Federal Emergency Management Agency (FEMA) nears the end of its Map Modernization Program, the agency, along with the National Oceanic and Atmospheric Administration, asked the Nationa...
