Two dams on the Elwha River, Washington State, USA trapped over 20 million m3 of sediment, reducing downstream sediment fluxes and contributing to erosion of the river's coastal delta. The removal of the Elwha and Glines Canyon dams between 2011 and 2014 induced massive increases in river sediment supply and provided an unprecedented opportunity to examine the response of a delta system to changes

These data were compiled to assess the risk of erosion to archaeological site preservation. The objective of the study is to evaluate changes in archaeological site condition over time as a function of two geomorphology based conceptual models that evaluate the extent to which sites are potentially affected by 1) erosion from gullies, and 2) wind-driven (aeolian) supply of river-sourced sand, resp

This U.S. Geological Survey data release consists multiple datasets used to simulate the extents of flood inundation along the Muddy River, near Moapa, Nevada. Flood-inundation extents equal the maximum area of flood inundation and were estimated using a coupled one-dimensional (1D) and two-dimensional (2D) hydraulic model. The modeled extents represent six annual exceedance probabilities simulate

This dataset consists of summary data for potential landscape sources of per- and poly-fluoroalkyl substances (PFAS). These summary items include facilities from the Environmental Protection Agency (EPA) PFAS Analytics Tools, which were pulled from its Enforcement and Compliance History Online (ECHO), areas affected by fires (burned and urban burned areas) from Monitoring Trends in Burn Severity (

Geologic structure and isopach maps were constructed by interpreting over 19,890 trackline kilometers of co-located multichannel boomer, sparker and chirp seismic reflection profiles from the continental shelf of the Delmarva Peninsula, including Maryland and Virginia state waters. In this region, Brothers and others (2020) interpret 12 seismic units and 11 regional unconformities. They interpret

Uncrewed aerial system (UAS) flights were conducted by the U.S. Geological Survey at an edge-of-field site located north of Medina River Natural Area near San Antonio, Texas on August 14, 2019, and July 8, 2022, to support efforts aimed at estimating edge-of-field erosion and potential sediment loading into the Medina River near San Antonio. Data provided here include imagery obtained during the f

Water supply lakes are the primary source of water for many communities in northern and western Missouri. Therefore, accurate and up-to-date estimates of lake capacity are important for managing and predicting adequate water supply. Many of the water supply lakes in Missouri were previously surveyed by the U.S. Geological Survey in the early 2000s (Richards, 2013) and in 2013 (Huizinga, 2014); how

The widespread distribution of Strophitus undulatus, as well as high intraspecific morphological variation, has led previous authors to doubt the taxon is representative of a single species. Here we provide detailed information for all the freshwater mussels and associated DNA sequence data utilized to test species boundaries in S. undulatus. These molecular data, in combination with morphological

We performed laboratory time-dependent creep and stress-oscillation earthquake simulations in uniaxial loading in compression and tension on four blocks of porphyritic dacite collected from pyroclastic deposits of Mt. Fugen, of the Unzen-dake volcanic complex in Japan (referred to as ‘Unzen volcano’). Experiments were carried out in the Experimental Volcanology and Geothermal Research Laboratory a

The dataset includes water-quality sensor readings collected by the U.S Geological Survey (USGS) from the Caloosahatchee River at the Franklin Lock and Dam and 12 open-air fiberglass tanks filled with Caloosahatchee River water used for mesocosm experiments testing the effects of elevated nutrients on harmful algal bloom (HAB) dynamics. This dataset contains water quality sensor readings from two

This data release includes whole rock (WR) geochemical data, and uranium-lead isotopic data collected using a sensitive high resolution ion microprobe-reverse geometry (SHRIMP-RG) instrument; the SHRIMP-RG is a type of secondary ion mass spectrometer (SIMS). Whole rock geochemistry data were analyzed at Bureau Veritas Commodities Canada Ltd. Laboratories in Vancouver, British Columbia, Canada. SHR

The data set contains information on potential population, economic, land cover, and infrastructure exposure to coastal hazards for coastal communities of the state of Georgia, USA. The type of information includes U.S. Census data on the number and types of residents, InfoGroup data on numbers and types of employees, county parcel values, NLCD land cover estimates, and infrastructure data on roa
