USGS Unveils Mobile Flood Tool for the Nation
The U.S. Geological Survey announced Friday the completion of a new mobile tool that provides real-time information on water levels, weather and flood forecasts all in one place on a computer, smartphone or other mobile device.
USGS Responds to Spring Flooding
U.S. Geological Survey field crews are measuring flooding across the country as spring weather is in full swing. Warming temperatures, increased precipitation and snowmelt have caused moderate to major flooding in the upper Midwest, East Coast, Central Plains and the Southeast portions of the country.

Precipitation-driven flood-inundation mapping of the Little Blue River at Grandview, Missouri
The U.S. Geological Survey (USGS), in cooperation with the City of Grandview, Missouri, assessed flooding of the Little Blue River at Grandview resulting from varying precipitation magnitudes and durations and expected land-cover changes. The precipitation scenarios were used to develop a library of flood-inundation maps that included a 3.5-mile...

Two-dimensional hydraulic analyses of Joachim Creek, De Soto, Missouri
A two-dimensional hydraulic model; water-surface profiles; and digital maps of water-surface elevation, velocities, and water depths were developed for a 6.7-mile reach of Joachim Creek within and near the city of De Soto, Missouri. Water-surface profiles were generated for the 10-, 4-, 2-, 1-, and 0.2-percent annual exceedance probability (10-,...

Incorporating water quality analysis into navigation assessments as demonstrated in the Mississippi River Basin
A description of historical and ambient water quality conditions is often required as part of navigational studies. This paper describes a series of tools developed by the USGS that can aid navigation managers in developing water quality assessments. The tools use R, a statistical software program, and provide methods to retrieve historical...
