Digital flood-inundation maps for a 3.4-mile reach of Fourmile Creek at Silver Grove, Kentucky (Ky.), were created by the U.S. Geological Survey (USGS) in cooperation with the City of Silver Grove and the U.S. Army Corps of Engineers Louisville District. Because the City of Silver Grove is subject to flooding from Fourmile Creek and the Ohio River (backwater flooding up Fourmile Creek), a set of flood-inundation maps was created for each flooding source independently and for combinations of possible flooding scenarios. The flood-inundation maps depict estimates of the areal extent and depth of flooding corresponding to a range of different gage heights (gage height is commonly referred to as “stage,” or the water-surface...
This community serves to document data and analysis collected by researchers within the Upper Midwest Water Science Center whose mission is to collect high-quality hydrologic data and conduct unbiased, scientifically sound studies of water resources within the Great Lakes and Upper Mississippi Basins. We strive to meet the changing needs of those who use our information—from the distribution, availability, and quality of our water resources to topic-oriented research that addresses current hydrological issues.
Digital flood-inundation maps for a 4.46-mile reach of the Blue River near Kansas City, Missouri, were created by the U.S. Geological Survey (USGS) in cooperation with the City of Kansas City, Missouri. The flood-inundation maps, accessed through the USGS Flood Inundation Mapping Program website at http://water.usgs.gov/osw/flood_inundation/ , depict estimates of the spatial extent and depth of flooding corresponding to select-water levels (stages) at the USGS streamgage 06893195 Blue River at Red Bridge Road, Kansas City, Missouri reference streamgage. Near-real-time stage data from the streamgage may be obtained from the USGS National Water Information System database at https://doi.org/10.5066/F7P55KJN. Flood...
This community catalog serves the USGS Pennsylvania Water Science Center. The Water Science Center's mission is to collect, analyze and disseminate the impartial hydrologic data and information needed to wisely manage water resources for the people of the United States and the Commonwealth of Pennsylvania. In Pennsylvania, the USGS's water-resources roots date back to the late 1800's, with the initiation of streamflow gaging on the Delaware and Susquehanna Rivers and the evaluation of groundwater resources in various parts of the Commonwealth. Today, the Pennsylvania Water Science Center's cadre of nearly 80 scientists, technicians, and support staff in New Cumberland, Exton, Pittsburgh, and Williamsport work in...

The domain of the model is as follows: Row River from Dorena dam to the confluence with the Coast Fork; Coast Fork from Cottage Grove dam to the confluence with the Middle Fork; Silk Creek from River Mile 1.7 to the confluence with the Coast Fork. The basis for these features is the Willamette Flood Insurance Study – Phase One (2013). The hydraulics and hydrology for the FIS were reused in the production of these polygons; the reports and information associated with the FIS are applicable to this product. The Digital Elevation Model (DEM) utilized for the Willamette FIS submittal was produced by combining multiple overlapping topographic surveys for the Middle Fork and Coast Fork of the Willamette River. This DEM...

The Digital Elevation Model (DEM) utilized for this Willamette FIS submittal was produced by combining multiple overlapping topographic surveys for the Middle Fork and Coast Fork of the Willamette River. The DEM was created from four sources: LIDAR of the Springfield area that was flown in 2008, LIDAR of Silk Creek that was flown in 2011, LIDAR of Fall Creek that was flown in 2012, and photogrammetry of the Middle Fork and Coast Fork of the Willamette River that was flown in 2004. In areas where no high-resolution elevation data were available, USGS National Elevation Dataset (NED) data were used to supplement the DEM. This feature represents the areas NED information is presented. The horizontal datum of the DEM...

This feature class represents inundated area for the Coast Fork of the Willamette River, the Row River and Silk Creek (west of Cottage Grove, OR) for eight different flows at the gage Willamette River at Goshen, OR (USGS 14157500). The flows are 12,000; 15,000; 21,450; 27,900; 33,900; 39,900; 46,800 and 62,300 cubic feet per second (cfs). These flows correspond to gage heights of 11.8, 13.2, 15.1, 16.3, 17.2, 17.9, 18.6 and 19.8 feet, respectively.

The U.S. Geological Survey (USGS) has a long history of working cooperatively with the South Carolina Department of Transportation to develop methods for estimating the magnitude and frequency of floods for rural and urban basins that have minimal to no regulation or tidal influence. As part of those previous investigations, flood-frequency estimates have been generated at selected regulated streamgages. This is the data release for the report which assesses the effects of impoundments on flood-frequency characteristics by comparing annual exceedance probability (AEP) streamflows from pre- and post-regulated (before and after impoundment) periods at 18 USGS long-term streamgages, which is defined as a streamgage...

The purpose of this workshop is to identify important hydro- and ecological relationships that will affect the ability of floodplain managers to optimize their approaches to providing: 1) fish habitat; 2) wildlife habitat; 3) nutrient and sediment processing; and 4) flood regulation. The resulting conceptual model will guide future floodplain science, including the development of numerical simulation models of high interest relationships. Twenty participants at the workshop included science experts on each of the four floodplain functions, policy analysts, and floodplain managers faced with making optimization decisions. The workshop report will focus on relationships of greatest need of quantification and how they...

Reliable estimates of the magnitude and frequency of floods are an important part of the framework for hydraulic-structure design and flood-plain management. Annual peak flows measured at U.S. Geological Survey streamgages are used to compute flood-frequency estimates at those streamgages. However, flood-frequency estimates also are needed at ungaged stream locations. A process known as regionalization was used to develop regression equations to estimate the magnitude and frequency of floods at ungaged locations. This dataset contains the supporting tables and updated hydrologic region boundaries used in the 2017 flood-frequency study for Georgia, South Carolina, and North Carolina.
