Increasing floodplain connectivity through urban stream restoration increases nutrient and sediment retention
Data collected to measure the effects of urban stream restoration on increasing hydrologic connectivity to floodplains and resulting floodplain ecosystem geomorphic and soil attributes, sediment and nutrient loading, and rates of nutrient biogeochemistry processes (denitrification; N and P mineralization).
Cumulative spring discharge and survey effort influence threatened Suwannee moccasinshell, Medionidus walkeri, occupancy and detection
Freshwater mussels (Unionidae) are among the most imperiled groups of organisms in the world. Unionids are plagued with a lack of basic information regarding species distributions, life history characteristics, and ecological and biological requirements. We assessed the influence of hydrologic factors on the occurrence of the Suwannee Moccasinshell, Medionidus walkeri, a federally threatened fresh
Supplemental stream-stage, discharge, and Escherichia coli datasets used in the assessment of water quality at Tumaccori National Historical Park and the Upper Santa Cruz River, 20092017
Tumaccori National Historical Park (TUMA) was established in 1908 to protect, preserve, and communicate the history of the old Spanish and Oodham mission church. In 2002, Congress expanded the Parks purpose and mission, increasing the Parks area to include more than 1 mile of the Santa Cruz River and its associated riparian area. As part of the USGSNPS Water-Quality Partnership, a three year inves
Time Series Electromagnetic Induction-Log Datasets, Including LogsCollected through the 2016 Water Year in South Florida
Time series electromagnetic induction-log (TSEMIL) datasets are collected from PVC cased or uncased monitoring wells to evaluate changes in water conductivity over time. TSEMIL datasets consist of a series of individual electromagnetic induction logs collected at a frequency of months or years that have been compiled into a dataset by eliminating small uniform offsets in bulk conductivity between
Time Series Electromagnetic Induction-Log Datasets, Including Logs Collected through the 2015 Water Year in South Florida
Time series electromagnetic induction-log (TSEMIL) datasets are collected from PVC cased or uncased monitoring wells to evaluate changes in water conductivity over time.

Post-wildfire debris-flow monitoring data, Arroyo Seco, 2009 Station Fire, Los Angeles County, California, November 2009 to March 2010.
This data release includes time-series data from a monitoring site located in a small drainage basin in the Arroyo Seco watershed in Los Angeles County, CA, USA (N3788964 E389956, UTM Zone 11, NAD83). The site was established after the 2009 Station Fire and recorded a series debris flows in the first winter after the fire. The data include three types of time-series: (1) 1-minute time series of ra
An Open Repository of Earthquake-Triggered Ground-Failure Inventories
Earthquake-triggered ground-failure, such as landsliding and liquefaction, can contribute significantly to losses, but our current ability to accurately include them in earthquake hazard analyses is limited. The development of robust and transportable models requires access to numerous inventories of ground failure triggered by earthquakes that span a broad range of terrains, shaking characteristi
Will fluctuations in salt marsh - mangrove dominance alter vulnerability of a subtropical wetland to sea-level rise?
To avoid submergence during sea-level rise, coastal wetlands build soil surfaces vertically through accumulation of inorganic sediment and organic matter. At climatic boundaries where mangroves are expanding and replacing salt marsh, wetland capacity to respond to sea-level rise may change. To compare how well mangroves and salt marshes accommodate sea-level rise, we conducted a manipulative field
Nevada WaterQualityWatch
WaterQualityWatch (http://waterwatch.usgs.gov/wqwatch/) is a USGS web site that provides access to real time water-quality data collected in surface waters throughout the United States as part of the USGS mission to describe water resources. Measurements include streamflow (through WaterWatch) water temperature, specific conductance, pH, dissolved oxygen, turbidity, and nitrate.
Nevada Long-Term Groundwater Data Network
Actively-measured periodic, continuous, and/or real-time wells with at least 20 years of measurements.
Nevada Active Water Level Network
Water levels and well information for wells that have been measured by the USGS or USGS cooperators at least once within the past 13 months.
Site and Groundwater-Quality Sample Data for Abandoned Underground Coal Mine Aquifers in West Virginia, July 13, 1973 through September 7, 2016
This Data Release is a compilation of existing water-quality data associated with groundwater resources originating from abandoned underground coal mines in West Virginia. Data were compiled from multiple sources for the purpose of understanding the suitability of groundwater from abandoned underground coal mines for public supply, industrial, agricultural, and other uses. This compilation include
