Historical simulated snowpack and other hydrometeorology data at 90 m for the Crown of the Continent and vicinity, United States and Canada, water years 1981-2020 Historical simulated snowpack and other hydrometeorology data at 90 m for the Crown of the Continent and vicinity, United States and Canada, water years 1981-2020
This data release contains historical SnowModel (Liston and Elder, 2006) output for the Crown of the Continent and surrounding areas in Montana and Idaho, USA; and Alberta and British Columbia, Canada from September 1, 1981 through August 31, 2020. Fifteen daily variables were simulated or derived for this release: (1) snow water equivalent (swed), (2) liquid precipitation (rpre), (3)...
Database of historical anthracite coal-mining infrastructure at the northern end of the Lackawanna syncline, Wayne, Susquehanna, and Lackawanna counties, Pennsylvania Database of historical anthracite coal-mining infrastructure at the northern end of the Lackawanna syncline, Wayne, Susquehanna, and Lackawanna counties, Pennsylvania
Abandoned railroads and infrastructure from the anthracite coal mining industry are significant features in abandoned mine lands and are an important part of history; however, these features are often lost and masked by the passage of time and the regrowth of forests. The application of modern light detection and ranging (lidar) topographic analysis, combined with ground-truthing "boots...
Model subareas and moisture zones used in a sensitivity analysis of a water-budget model completed in 2022 for the islands of Oahu and Maui, Hawaii Model subareas and moisture zones used in a sensitivity analysis of a water-budget model completed in 2022 for the islands of Oahu and Maui, Hawaii
A sensitivity analysis of groundwater-recharge estimates from a water-budget model was completed for the islands of Oahu and Maui, Hawaii (Johnson and others, 2023). Results of the sensitivity analysis were used to quantify the relative importance of selected model parameters to recharge estimates for three moisture zones (dry, mesic, and wet) on Oahu and Maui. These shapefiles contain...
Chronic Wasting Disease Modeling for Bridger Teton National Forest Structured Decision Making (cwd-btnf-sdm-v2) Chronic Wasting Disease Modeling for Bridger Teton National Forest Structured Decision Making (cwd-btnf-sdm-v2)
This software release contains the code necessary to run the chronic wasting disease (CWD) and elk habitat selection models used to support the U.S. Forest Service decision on whether to continue to permit supplemental feeding of elk on USFS land. The models allow for four different management alternatives: continued feeding, emergency feeding, phase-out after three years, or no feeding...
North Lake Mechant Landbridge Restoration (TE-44): 2021 land-water classification North Lake Mechant Landbridge Restoration (TE-44): 2021 land-water classification
The Louisiana State Legislature created the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in order to conserve, restore, create and enhance Louisiana's coastal wetlands. The wetland restoration plans developed pursuant to these acts specifically require an evaluation of the effectiveness of each coastal wetlands restoration project in achieving long-term solutions to...
Hurricane Sandy induced changes to piping plover nesting habitat on Edwin B. Forsythe National Wildlife Refuge, New Jersey Hurricane Sandy induced changes to piping plover nesting habitat on Edwin B. Forsythe National Wildlife Refuge, New Jersey
The barrier islands and coastal beaches along the Atlantic Coast are dynamic systems continuously affected and shaped by tides and weather events (Davidson-Arnott 2010). Occasionally weather events are large enough to generate or expand beach overwash areas and may inundate all or part of the islands. Nor'easters, are known to play a significant role in shaping beach morphology along the...
