SWAT Model Archive for Simulation of Hydrology, Suspended Sediment and Nutrients in Selected Tributary Watersheds of Lake Erie, New York
This U.S. Geological Survey (USGS) data release contains model scenario input and output files and nine hydrology and water-quality models developed using the Soil and Water Assessment Tool (SWAT). The models represent nine watersheds in eastern New York that drain to Lake Erie or the Niagara River and were created, calibrated, and validated for hydrology, sediment, and nutrients as baseline scena
Surficial geologic map database for the Blanca Peak, Walsenburg, Trinidad, and Alamosa 30' x 60' quadrangles, Colorado
This data release presents geologic map data for the surficial geology of the Blanca Peak, Walsenburg, Trinidad, and Alamosa 30' x 60' quadrangles, Colorado, and an adjacent area to the north of the Blanca Peak quadrangle. The map area lies within two physiographic provinces of Fenneman (1928): the Southern Rocky Mountains Province, and the Great Plains Province, Raton Section. Geologic mapping is
Bathymetry and Acoustic Backscatter data for Jenkinson Lake, California collected during three USGS field activities, 2022-604-FA, 2022-649-FA, and 2023-634-FA
Bathymetry and acoustic-backscatter data were collected during three separate SWATHPlus surveys of Jenkinson Lake, California to determine any impacts on the lake floor following the 2021 Caldor fire. Data were collected and processed by the U.S. Geological Survey (USGS), Pacific Coastal and Marine Science Center (PCMSC) with fieldwork activity numbers 2022-604-FA (January 2022), 2022-649-FA (Augu
Post-fire debris-flow hazard model output files, Santa Fe Municipal Watershed, New Mexico
Wildfires are increasing in size and severity because of a warming climate in combination with overstocked forests. Fire increases the likelihood of debris flows, posing significant threats to life, property, and water supplies. Post-fire debris flows are a substantial, increasing hazard in the Santa Fe Municipal Watershed and other similar forested watersheds across the western United States. The
Urban tree cover provides consistent mitigation of extreme heat in arid but not humid cities - data release
Urban land cover types influence the urban microclimates. However, recent work indicates the magnitude of land cover’s microclimate influence is affected by aridity. Moreover, this variation in cooling and warming potentials of urban land cover types can substantially alter the exposure of urban areas to extreme heat. Our goal is to understand both the relative influences of urban land cover on lo
Airborne magnetic and radiometric survey, Medicine Bow Mountains, Wyoming, 2023
This data release provides digital flight line data for a high-resolution airborne magnetic and radiometric survey over the Medicine Bow Mountains in southern Wyoming. The airborne survey was jointly funded by the Earth Mapping Resources Initiative and the Wyoming State Geological Survey (WSGS). The survey was designed to meet complementary needs related to geologic mapping and characterization of
Delmarva Peninsula Stream Health and Habitat Assessments in Maryland and Delaware (2022)
U. S. Geological Survey (USGS) scientists completed a data collection campaign from the 25th of April to the 10th of June in 2022, using various methods to record geomorphic and habitat indicators throughout 30 streams on the Delmarva Peninsula. Field methods included GNSS surveys, gravelometer-based pebble count readings, visual assessments, and riparian analyses. This metadata record contains al
Datasets for Assessment of Nutrient Load Estimation Approaches for Small Urban Streams in Durham, North Carolina, 2009-2020
In cooperation with the City of Durham Public Works Department Stormwater Division, the U.S. Geological Survey (USGS) conducted a study to evaluate whether alternate monitoring strategies that incorporated samples collected across an increased range of streamflows would improve nutrient load estimates for Ellerbe and Sandy Creeks, two small, highly urbanized streams in the City of Durham, North Ca
Tiltmeter data from Kīlauea’s East Rift Zone station JKA from August 1 to September 15, 2014
Tiltmeter data from station Jonika Flow (JKA) used in the publication "Pre-existing ground cracks as lava flow pathways at Kīlauea in 2014" by Tim R. Orr, Edward W. Llewellin, Kyle R. Anderson, and Matthew R. Patrick. These data were collected in 2014 by Asta Miklius of the USGS Hawaiian Volcano Observatory.
