Linking Selenium Sources to Ecosystems: Irrigation

Adverse effects of selenium (Se) on fish and waterfowl in wetlands receiving agricultural drainage occurred in the 1980s in the San Joaquin Valley of California. The identified mechanisms of Se enrichment helped resolve Se toxicity problems associated with irrigated agriculture in the arid West. Bioaccumulation of Se in ancient marine sediments is postulated as a primary pathway in source...

Linking Selenium Sources to Ecosystems: Refining

The San Francisco Bay-Delta receives selenium (Se) internally from oil refineries and externally through riverine agricultural discharges. Predator species considered at risk from Se consume the estuary’s dominant bivalve, C. amurensis, an efficient bioaccumulator of Se. Modeling predicts site-specific ecological risk and derives a range of protective Se concentrations for use by decision-...

National Water-Quality Assessment (NAWQA): 1991-2012

In 1991, Congress established the National Water-Quality Assessment (NAWQA) Project to address where, when, why, and how the Nation's water quality has changed, or is likely to change in the future, in response to human activities and natural factors. This page discusses the first two decadal cycles of NAWQA research from 1991 through 2012.

Flood Inundation Map (FIM) Libraries

The Flood Inundation Mapping Program focuses on developing flood inundation map libraries and helping communities pair those libraries with real-time stream data and National Weather Service flood forecasts to form a two-dimensional flood warning system. Together, these products can help communities estimate the extent of a flood and identify at-risk areas and resources in advance of...

National Brackish Groundwater Assessment

All water naturally contains dissolved solids that can make it "brackish" or distastefully salty. The amount of freshwater for drinking-water, agricultural, industrial, and environmental needs has declined in many areas and has led to concerns about future availability. The USGS conducted a national assessment of brackish aquifers that could supplement or replace freshwater sources.

Emerging Flood Inundation Mapping Technologies

The following technologies represent state-of-the-art tools, methodologies, and techniques that the USGS and our partners are researching and testing. Most of these techniques are experimental and not publicly available, but could significantly improve our ability to plan for and respond to flooding events in the future.

Flood Inundation Mapping - Loss Estimation

Using a flood inundation map library to estimate where floodwaters will go and how deep they will be is crucial for planning and preparing for floods. By performing loss-estimation modeling, the potential physical, economic, and social impacts of disasters can be calculated, helping communities anticipate the effects of flooding and identify specific strategies to reduce losses and speed...

2011 - The Year of the Flood

2011 proved to be another record-breaking flood year in the United States. USGS Water Science Center personnel from North Dakota to Louisiana measured springtime floods on the Red River of the North, the Ohio River, the Mississippi River, and many tributaries. The Missouri River and its tributaries saw record-breaking snow-melt runoff through the summer, followed closely by Hurricane Irene and...
