Aquifer framework datasets used to represent the Kingshill aquifer, Island of St. Croix Aquifer framework datasets used to represent the Kingshill aquifer, Island of St. Croix
The Kingshill aquifer resides under St. Croix, an Island in the U.S. Virgin Islands. The Island of St. Croix is mountainous in the northwestern and eastern regions of the island and the central and southwest regions contain rolling hills and plains. The Kingshill aquifer underlies the plains of St. Croix. The aquifer is composed primarily of limestone and marl and has a maximum saturated
Aquifer framework datasets used to represent the Marshall aquifer, Michigan Aquifer framework datasets used to represent the Marshall aquifer, Michigan
The Marshall aquifer underlies much of the Lower Peninsula of Michigan and has a maximum thickness of 493 feet (Lampe, 2009). The aquifer consists mainly of medium-grained sandstone and is overlain by Pennsylvanian-age rocks and glacial deposits and underlain by the Devonian-Mississippian-age confining unit. The Marshall aquifer is one of the most productive aquifers in the state where
Aquifer framework datasets used to represent the Pecos River Basin alluvial aquifer, Texas, New Mexico Aquifer framework datasets used to represent the Pecos River Basin alluvial aquifer, Texas, New Mexico
The Pecos River Basin alluvial aquifer, hereinafter referred to as the "Pecos aquifer", is located in western Texas and southeastern New Mexico. The aquifer is primarily composed of alluvial sand and gravel deposits mantled by sand and silt. The Pecos aquifer overlies Permian, Triassic, and Cretaceous-age rocks. The saturated thickness of the aquifer ranges from 0 to 1000 feet. The...
Aquifer framework datasets used to represent the Roswell Basin aquifer system, New Mexico Aquifer framework datasets used to represent the Roswell Basin aquifer system, New Mexico
The Roswell Basin aquifer system is located in southeastern New Mexico. It is composed of an alluvial aquifer and an underlying carbonate-rock aquifer. The aquifer covers an area of about 2,200 square miles and the alluvial aquifer covers about 1,200 square miles of the eastern half of this area. The alluvial aquifer primarily consists of Quaternary sediments and the carbonate-rock...
Aquifer framework datasets used to represent the Rush Springs aquifer, Oklahoma Aquifer framework datasets used to represent the Rush Springs aquifer, Oklahoma
The Rush Springs aquifer resides in west-central Oklahoma with an area of about 1,400 square miles. The aquifer consists of the Rush Springs Sandstone and the Marlow Formation which are part of the Whitehorse Group of Permian age (HA 730-E). The Rush Springs Sandstone has a maximum thickness of about 300 feet and the Marlow Formation has a maximum thickness of about 125 feet. The aquifer...
Aquifer framework datasets used to represent the Southern Nevada volcanic-rock aquifers, Nevada Aquifer framework datasets used to represent the Southern Nevada volcanic-rock aquifers, Nevada
The Southern Nevada volcanic-rock aquifers reside in southern-central Nevada. This group of aquifers can be categorized into welded tuff, bedded tuff, and lava flow aquifers. Each of these categories possess different physical characteristics and have varying degrees of welding and number of interconnected joints. The lithology of these aquifers is primarily dependent on mode of eruption...
Aquifer framework datasets used to represent the Western Interior Plains aquifer system, Arkansas, Colorado, Kansas, Missouri, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, Wyoming Aquifer framework datasets used to represent the Western Interior Plains aquifer system, Arkansas, Colorado, Kansas, Missouri, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, Wyoming
The Western Interior Plains aquifer system is located in parts of Arkansas, Colorado, Kansas, Missouri, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming and covers an area of more than 220,800 square miles. The thickness of the aquifer system ranges from 500 feet in eastern Colorado (HA 730-D) to as much as 10,000 feet in western Oklahoma (PP_1414B). This aquifer system...
Archive of Bank Stability and Toe Erosion Model (BSTEM) Simulations of Caulks Creek, Wildwood, Missour Archive of Bank Stability and Toe Erosion Model (BSTEM) Simulations of Caulks Creek, Wildwood, Missour
The Bank Stability and Toe Erosion Model (BSTEM) version 3.3.1 (Ursic and Langendoen, 2021) was used to predict bank retreat at five locations along Caulks Creek, Wildwood, Missouri, for a selection of design storm scenarios. BSTEM is a macro-enabled Excel spreadsheet (.xlsm file) that simulates the retreat of a bank profile due to a combination of fluvial and geotechnical processes...
Archive of Chirp Subbottom Profile Data Collected in 2022 From Boca Chica Key, Florida Archive of Chirp Subbottom Profile Data Collected in 2022 From Boca Chica Key, Florida
As part of the Coastal Sediment Availability and Flux and Defense Advanced Research Protection Agency (DARPA) Reefense projects, scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center (SPCMSC) conducted a nearshore geophysical survey to map the shoreface and inner shelf, as well as characterizing stratigraphy near Boca Chica Key, Florida (FL)...
Archive of Chirp Subbottom Profile Data Collected in 2023 From Oahu, Hawaii Archive of Chirp Subbottom Profile Data Collected in 2023 From Oahu, Hawaii
As part of the Coastal Sediment Availability and Flux and Defense Advanced Research Protection Agency (DARPA) Reefense projects, scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center (SPCMSC) conducted a nearshore geophysical survey to map the shoreface and inner shelf, as well as characterizing stratigraphy near Oahu, Hawaii (HI) in May 2023...
Archive of hydraulic and hydrologic models used in the Stoney Brook watershed in Carlton and St. Louis Counties, Minnesota, 2008–2024 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...
Archive of hydrologic and hydraulic models used in the simulation of hydraulic characteristics of Caulks Creek, Wildwood, Missouri 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...
