Feb. 25, 2015 -- Developed by the U.S. Geological Survey (USGS), in cooperation with the City of Overland Park, Kan., and the City of Kansas City, Mo., a new interactive online tool to improve flood warnings and emergency management is now available in select parts of Johnson County, Kan., and Jackson County, Mo.
The new tool will help emergency managers from national, state and local agencies make quick decisions about when and how to evacuate residents threatened by rising floodwaters. The flood-inundation maps, developed using USGS streamgages already in place, will enable better flood preparedness and response.
The USGS Flood Inundation Mapping product is an interactive web-based tool that shows the extent of flooding at selected rivers and streams across the U.S. The maps illustrate where flooding is occurring, as well as areas that will likely flood in the near future. The flood-forecasting portion of the map is determined by using real-time USGS streamgage information and flood-forecast information by the National Weather Service (NWS).
"This technology will greatly help the public and officials minimize flood deaths and damage in the Kansas City metropolitan area," said Lynda Hoffman, division manager, Waterways Division, Kansas City Water Services. "When flood events are predicted by the NWS, the inundation mapping will provide crucial information on the web to residents and business along the Blue River for deciding when to evacuate or move critical equipment to higher ground."
Locally, the map features the Blue River and its tributaries, including Tomahawk and Indian Creeks in Johnson County, Kan., and Indian and Brush Creeks in Jackson County, Mo. The flood-inundation maps will encompass nearly 60 miles of the Blue River and its tributaries and is the largest contiguous-mapped network of its kind in the country.
For more than 125 years, the USGS has monitored flow in selected streams and rivers across the U.S. The information is routinely used for water supply and management, monitoring floods and droughts, bridge and road design, determination of flood risk, and for many recreational activities.
