A Google Earth Engine Application for Exploring Potential Changes in Design Peak-flow of US Urban Areas Driven by Land Cover Change A Google Earth Engine Application for Exploring Potential Changes in Design Peak-flow of US Urban Areas Driven by Land Cover Change
A Google Earth Engine (GEE) application was developed to explore the spatial distribution map of potential percent change (2020 compared to 1985) of design peak-flow, an average percent change (average of pixels within the selected urban area) as text, and three time-series (1985-2020) charts of design peak-flow for three precipitation frequencies (with three recurrence interval and...
Concentration Data for 12 Elements of Concern Used in the Development of Surrogate Models for Estimating Elemental Concentrations in Surface Water of Three Hydrologic Basins (Delaware River, Illinois River and Upper Colorado River) Concentration Data for 12 Elements of Concern Used in the Development of Surrogate Models for Estimating Elemental Concentrations in Surface Water of Three Hydrologic Basins (Delaware River, Illinois River and Upper Colorado River)
The release of metals (or metalloids) to surface water can involve both natural and anthropogenic sources. Elevated metals concentrations can pose a risk to human health, wildlife, and ecosystem health, with the modes of toxicity and extent of risk varying as a function of the specific metal, its chemical form and the matrix with which it is associated (for example, dissolved versus...
Whiskey Island Caillou Lake Headlands restoration area 2016–2019 shorelines, Louisiana Barrier Island Comprehensive Monitoring Program Whiskey Island Caillou Lake Headlands restoration area 2016–2019 shorelines, Louisiana Barrier Island Comprehensive Monitoring Program
This data package includes a high-water shoreline position map and a structures map for each year from 2016–2019 for the Natural Resource Damage Assessment (NRDA) Caillou Lake Headlands project area (TE-0100), also known as Whiskey Island. The project created 170 acres of marsh habitat and 917 acres of dune and beach habitat on Whiskey Island in Terrebonne Parish using material dredged...
Caminada Headland restoration area 2016-2019 shorelines, Louisiana Barrier Island Comprehensive Monitoring Program Caminada Headland restoration area 2016-2019 shorelines, Louisiana Barrier Island Comprehensive Monitoring Program
This data package includes a high-water shoreline position map and a structures map for each year from 2016–2019 for the National Fish and Wildlife Foundation (NFWF) Caminada Headland Beach and Dune Restoration Incr2 project area (BA-0143). The project restored 489 acres of beach and dune habitat along more than seven miles of Caminada Headland in Jefferson and Lafourche Parishes through...
Selection and Survival of Greater Sage-Grouse Broods in Mesic Areas of Long Valley, California (2003 - 2018) Selection and Survival of Greater Sage-Grouse Broods in Mesic Areas of Long Valley, California (2003 - 2018)
We evaluated brood-rearing habitat selection and brood survival of greater sage-grouse (Centrocercus urophasianus; hereafter, sage-grouse) in Long Valley, California, an area where the water rights are primarily owned by the city of Los Angeles and water is used locally to irrigate for livestock. This area thus represents a unique balance between the needs of wildlife and people that...
Hydroacoustic mapping of physical habitat for imperiled freshwater mussels in the St. Croix River (ver. 2.0, February 2025) Hydroacoustic mapping of physical habitat for imperiled freshwater mussels in the St. Croix River (ver. 2.0, February 2025)
Recent advances in hydroacoustic technology are proving to be valuable tools for mapping habitat features for sedentary biota such as freshwater mussels, and has the potential to identify and quantify habitat features. The Spectaclecase (Margaritifera monodonta) and Salamander (Simpsonaias ambigua) are imperiled mussels that are typically associated with rock structures (e.g., wing dams...
