Copper River and Knik River Bathymetric Surveys at Select Alaska Highway Bridges near Flag Point and Butte, Alaska, 2020 Copper River and Knik River Bathymetric Surveys at Select Alaska Highway Bridges near Flag Point and Butte, Alaska, 2020
In 2020, the Alaska Science Center and the Idaho Water Science Center conducted bathymetric surveys at three highway bridge structures. The bridge structures (NBI 331 and 1187) at Flag Point near Cordova, AK are located on Alaska State Route 10 (commonly referred to as the Copper River Highway). Bridge structure NBI 539 on the Knik River is located on the Old Glenn Hwy near Butte, AK...
Hydrologic and soil data associated with selected vacant deconstruction lots in St. Louis, Missouri, 2018-2020 Hydrologic and soil data associated with selected vacant deconstruction lots in St. Louis, Missouri, 2018-2020
As the urban landscape and municipal infrastructure in U.S. cities changes in response to socio-economic conditions, so does the manner in which water cycles through these cities. The modulation of hydrologic processes (e.g., runoff, infiltration, evapotranspiration) by land use and land cover has implications for resilience, sustainability, and optimizing municipal service functions...
Average well color development data for water samples from six locations within the historic section of Mammoth Cave National Park, Kentucky Average well color development data for water samples from six locations within the historic section of Mammoth Cave National Park, Kentucky
Water samples were collected from six cave locations where Actinobacterial mats appeared to be plentiful. Community-level physiological capabilities were evaluated using Biolog-Ecolog plates inoculated with cave water dosed with 0 or 0.10 milligrams per liter (mg/L) of erythromycin. The data were transformed into average well color development (AWCD). The transformation is done by...
DSWEmod surface water map composites generated from daily MODIS images - California DSWEmod surface water map composites generated from daily MODIS images - California
USGS researchers with the Patterns in the Landscape ? Analyses of Cause and Effect (PLACE) project are releasing a collection of high-frequency surface water map composites derived from daily Moderate Resolution Imaging Spectroradiometer (MODIS) imagery. Using Google Earth Engine, the team developed customized image processing steps and adapted the Dynamic Surface Water Extent (DSWE) to...
