Archive of hydraulic and hydrologic models used in the Stoney Brook watershed in Carlton and St. Louis Counties, Minnesota, 2008–2024
The U.S. Geological Survey (USGS), in cooperation with the Fond du Lac Band of Lake Superior Chippewa (FDLB), Minnesota, analyzed the hydrologic and hydraulic conditions within the Stoney Brook watershed. The Stoney Brook watershed covers an area of 100.8 square miles in Carlton and St. Louis counties with most of the watershed within the Fond du Lac Reservation. Wild rice, which is harvested by t
Archive of the Hydrologic and Hydraulic Models used in the Analyses of the Silver Creek Basin and Selected Tributaries Associated with Scott Air Force Base, Illinois, 1992–2050
The U.S. Geological Survey (USGS), in cooperation with Scott Air Force Base (SAFB), Illinois, assessed the effects of temporal land-use development in the Silver Creek Basin, the potential effects of projected changes in future precipitation, and the effects of added detention storage in selected tributaries near SAFB. A hydrologic model was used to simulate precipitation runoff and streamflows fo
Archive of hydrologic and hydraulic models used in the simulation of hydraulic characteristics of Caulks Creek, Wildwood, Missouri
Substantial incision and widening of Caulks Creek within the City of Wildwood, Missouri, in western St. Louis County, poses a threat to stormwater and transportation infrastructure along with effects to residential and recreational property. Hydrologic and hydraulic models were used to estimate probabilistic streamflows and characterize and assess spatial and temporal changes in erosion factors
Archive of the Hydraulic Model used in the Two-Dimensional Simulation of the Chain of Lakes on the Fox River near McHenry, Illinois
Forecasts of flows entering and leaving the Chain of Lakes on the Fox River in northeastern Illinois are critical information to water-resource managers operating the Stratton Dam at McHenry, Illinois. These managers determine the optimal operation of the Stratton Dam at McHenry, Ill., to manage Chain of Lakes pool levels and to help mitigate flooding in the Chain of Lakes system. In 2020, the U.S
Hydraulic Model Archive and Fluvial Egg Drift Simulator (FluEgg) Results for Simulations of Invasive Carp Egg and Larval Drift in the Maumee River, Ohio (ver. 1.1, July 2023)
The U.S. Geological Survey simulated the drift and dispersal of invasive carp eggs and larvae in the Maumee River, Ohio, using the Fluvial Egg Drift Simulator (FluEgg) (Garcia and others, 2013; Domanski, 2020). The hydraulic inputs used in the FluEgg simulations were generated using a one-dimensional Hydrologic Engineering Center-River Analysis System (HEC-RAS) 5.0.7 model of the Maumee River (HEC
Geospatial datasets for the flood-inundation study for the Iowa River at the Meskwaki Settlement in Iowa, 2019
Digital flood-inundation maps for a 9.3-mile reach of the Iowa River along the Meskwaki Settlement, Iowa, were created by the U.S. Geological Survey (USGS) in cooperation with the Sac and Fox Tribe of the Mississippi River in Iowa. The flood-inundation maps, which can be accessed through the USGS Flood Inundation Mapping Science web site at https://water.usgs.gov/osw/flood_inundation/ depict estim
Geomorphic change, hydrology, and hydraulics of Caulks Creek, Wildwood, Missouri
Caulks Creek is a small stream that flows through the city of Wildwood in western St. Louis County, Missouri. The U.S. Geological Survey, in cooperation with the city of Wildwood, has documented historical and recent geomorphic change along Caulks Creek, simulated the hydrologic and hydraulic response of Caulks Creek to a variety of design storm scenarios, and simulated bank retreat resulting from

Reproduction of grass carp (Ctenopharyngodon idella) in the Maumee River, Ohio: Part 2—Optimal river conditions for egg and larval drift
This study uses a one-dimensional steady-state hydraulic model and the Fluvial Egg Drift Simulator (FluEgg) to model the drift and dispersion of grass carp eggs and larvae in the Maumee River, Ohio, for 180 scenarios representing different combinations of 10 river flows, 6 water temperatures, and 3 spawning locations. The FluEgg simulations were used to quantify in-river suspended hatching rates (

Reproduction of grass carp (Ctenopharyngodon idella) in the Maumee River, Ohio: Part 1—Spawning area identification using bidirectional drift modeling
Control of invasive grass carp (Ctenopharyngodon idella) populations in the Western Lake Erie Basin merits adaptive management guided by the best available science. Presently (2024), capture of mature grass carp in rivers during spawning season is most efficient, so knowing when and where grass carp are spawning is essential information for natural resource agencies. Using bidirectional drift mode

Effects of climate change on the hydrologic and hydraulic response of the Caulks Creek basin, Wildwood, Missouri
The city of Wildwood, Missouri, has identified fluvial erosion along Caulks Creek as a management priority due to potential effects to infrastructure and property. The upper and middle reaches of Caulks Creek flow intermittently (only immediately after precipitation), whereas the lower reach flows perennially. This study examines the effects of climate change and added storage on the hydrologic an

Flood-inundation and flood-mitigation modeling of the West Branch Wapsinonoc Creek Watershed in West Branch, Iowa
The U.S. Geological Survey (USGS) in cooperation with the city of West Branch and the Herbert Hoover National Historic Site of the National Park Service assessed flood-mitigation scenarios within the West Branch Wapsinonoc Creek watershed. The scenarios are intended to demonstrate several means of decreasing peak streamflows and improving the conveyance of overbank flows from the West Branch Wapsi
