Model Archive: Simulation of Sediment Transport, Middle Channel of St. Clair River Delta, Michigan Model Archive: Simulation of Sediment Transport, Middle Channel of St. Clair River Delta, Michigan
This archive contains results of flow and sediment transport simulations of a reach of the Middle Channel of the St. Clair River delta, Michigan using the iRIC modeling system and the Flow and Sediment Transport with Morphologic Evolution of Channels (FASTMECH) solver. Two hydraulic model simulations were used to determine lateral eddy viscosity and roughness settings. A third simulation...
U-Pb and Ar-Ar age data and whole rock geochemistry data of igneous and metasedimentary rocks of northeast Afghanistan (ver. 2.0, June 2024) U-Pb and Ar-Ar age data and whole rock geochemistry data of igneous and metasedimentary rocks of northeast Afghanistan (ver. 2.0, June 2024)
This dataset accompanies the proposed publication, 'Geochronology and geochemistry of igneous and metasedimentary rocks of northeast Afghanistan: A refinement of the timing and origin of crustal terranes', which focuses on refining the geochronology and geochemistry of these rocks during multiple time periods of accretion, regional metamorphism, and magmatic activity. The analyses were...
Water Surfaces Elevations from Pressure Transducers on the Tanana River near Fairbanks, Alaska, 2016 Water Surfaces Elevations from Pressure Transducers on the Tanana River near Fairbanks, Alaska, 2016
This dataset includes locations, and water surface elevations from two submersible pressure transducers deployed in the channel of the Tanana River downstream of Fairbanks Alaska in 2016.
Data Supporting Studies of Brant and Other Waterfowl Disturbance Behavior, Distribution, and Diet at Izembek Lagoon, Alaska, 1985-1988 Data Supporting Studies of Brant and Other Waterfowl Disturbance Behavior, Distribution, and Diet at Izembek Lagoon, Alaska, 1985-1988
This data package presents legacy data collected during 1985-1988 at Izembek Lagoon on the western end of the Alaska Peninsula. The data were collected in support of a multi-year study focused on aircraft disturbance of waterfowl, particularly Black Brant, Emperor Geese, and Cackling Geese. The study was conducted at Izembek Lagoon and included several study sites within the lagoon...
Velocity and Water-Quality Data for the Maumee River Between Defiance and Toledo, Ohio, 2019 Velocity and Water-Quality Data for the Maumee River Between Defiance and Toledo, Ohio, 2019
As part of the Great Lakes Restoration Initiative (GLRI) project template 774-18 entitled “Development of monitoring and response methodologies, and implementation of an Adaptive Management Framework to work towards Eradication of Grass Carp in Lake Erie” an integrated bathymetric/hydrodynamic/water-quality survey of the Maumee River (Ohio) was completed by the U.S. Geological Survey...
Compilation of Geospatial Data (GIS) for the Mineral Industries and Related Infrastructure of Select Countries in Southwest Asia Compilation of Geospatial Data (GIS) for the Mineral Industries and Related Infrastructure of Select Countries in Southwest Asia
The U.S. Geological Survey (USGS) has compiled a geodatabase containing mineral-related geospatial data for 10 countries of interest in Southwest Asia (area of study): Afghanistan, Cambodia, Laos, India, Indonesia, Iran, Nepal, North Korea, Pakistan, and Thailand. The data can be used in analyses of the extractive fuel and nonfuel mineral industries and related economic and physical...
