Compilation of actual evapotranspiration and vegetation indices along critical riparian zones on the Navajo Nation from 2013-2023 Compilation of actual evapotranspiration and vegetation indices along critical riparian zones on the Navajo Nation from 2013-2023
These data were compiled for monitoring riparian zone trends and changes in the Navajo Nation as part of a study to document riparian ecosystem health and its water use in support of potential restoration efforts. The objective of our study was to monitor the short and medium-term effects on the riparian vegetation in relation to evapotranspiration changes, drought, and other...
Geospatial data, flood-frequency analysis, and surface-water model archive for streamflow extents and hydraulic characteristics of Meadow Valley Wash at Stuart Ranch, near Rox, Nevada Geospatial data, flood-frequency analysis, and surface-water model archive for streamflow extents and hydraulic characteristics of Meadow Valley Wash at Stuart Ranch, near Rox, Nevada
This U.S. Geological Survey data release consists of multiple datasets used to simulate the streamflow extents and hydraulic characteristics of Meadow Valley Wash at Stuart Ranch near Rox, Nevada. Streamflow extents equal the maximum area of flow inundation and were estimated using a two-dimensional (2D) hydraulic model. The modeled extents represent baseflow and six annual exceedance
Carbonate Budgets, Structure-from-Motion Products, and Topographic Complexity Measurements From Restored and Non-restored Areas of Coral Reefs in the Lower Florida Keys Carbonate Budgets, Structure-from-Motion Products, and Topographic Complexity Measurements From Restored and Non-restored Areas of Coral Reefs in the Lower Florida Keys
During the summers of 2022 and 2023, U.S. Geological Survey (USGS) researchers conducted underwater surveys aimed at quantifying the impact that past coral restoration by Mote Marine Laboratory had on the reef-accretion process. The surveys were conducted along paired transects representing restored and non-restored areas of eight offshore reefs and three patch-reef sites in the Lower...
Diver-Based Structure-from-Motion Imagery From Coral Reef Restoration Surveys in the Lower Florida Keys: July 2022 and July 2023 Diver-Based Structure-from-Motion Imagery From Coral Reef Restoration Surveys in the Lower Florida Keys: July 2022 and July 2023
During the summers of 2022 and 2023, U.S. Geological Survey (USGS) researchers conducted underwater photographic surveys aimed at quantifying the impact that past coral restoration by Mote Marine Laboratory had on the reef-accretion process. A total of 39,840 non-georeferenced diver-based images were collected. The surveys were conducted along paired transects (approximately 10x2 meter...
Per- and polyfluoroalkyl substances (PFAS) and wastewater indicator compounds measured in polar organic chemical integrative samplers (POCIS), and cyanotoxin concentrations measured in solid phase adsorption toxin trackers (SPATTs), in the lower Columbia Per- and polyfluoroalkyl substances (PFAS) and wastewater indicator compounds measured in polar organic chemical integrative samplers (POCIS), and cyanotoxin concentrations measured in solid phase adsorption toxin trackers (SPATTs), in the lower Columbia
This data release contains the analytical results of three contaminant classes in water using two types of passive sampling devices. Samples were collected at eight sites in the lower Columbia River and two sites in the lower Willamette River in Oregon and Washington. A Polar Organic Compound Integrating Sampler (POCIS) and a Solid-Phase Adsorption Toxin Tracker (SPATT) sampler were...
Topographic Wetness Indexes for the Upper and Lower Colorado River Basins Topographic Wetness Indexes for the Upper and Lower Colorado River Basins
This U.S. Geological Survey (USGS) data release describes two 30-meter (m) raster datasets of topographic wetness indexes (TWI) for the Upper and Lower Colorado River basins. The data reside in GeoTIFF (Geographic Tagged Imaged File Format) multiplied by 10 and saved as an integer file to reduce space (colorado14_twX100i.tif and colorado15_twiX100.tif). The TWI units are dimensionless...
