The U.S. Geological Survey deployed seven submersible pressure transducers on the bottom of the Salcha River in July 2018. An additional transducer was left out of the water to correct for barometric pressure fluctuations. At the time of deployment, the bank position near each transducer and the water-surface elevation were measured with Global Navigation Satellite System (GNSS) equipment. The transducers recorded a depth measurement every 15-min until the recovery of five of the seven in October. We adjusted the water elevation measured at deployment by the difference between the depth measured at deployment and each subsequent depth measurement to derive the water-surface elevation at 15-min intervals. The data...
This USGS Data Release represents Soil-Water Balance (SWB) groundwater infiltration modeling results for the Lower Colorado River Basin (LCRB). The data release was produced in compliance with 'open data' requirements as a way to make the scientific data associated with USGS research efforts and publications available to the public. There are 3 separate datasets associated with this Data Release: SWB model results from simulations run using projected climate data, summarized by month from 1950 through 2099, for the LCRB within the United States SWB model results from simulations run using projected climate data, summarized by month from 1950 through 2099, for the Grand Canyon region SWB model results from simulations...

Twenty one submersible pressure transducers were deployed along the Green River near Jensen Utah in late February 2018. At some locations two transducers were deployed at different elevations to capture the expected range of water level fluctuations, an "upper" and "lower" transducer. Two additional transducers were left out of the water to correct for barometric pressure fluctuations. At the time of deployment, the position of a reference point located on a t-post to which each transducer was mounted was measured with real-time kinematic GPS equipment. In addition, a tape down or the distance between the reference point to the water surface was recorded.The transducers collected a depth measurement every 15 minutes...

Censored and uncensored generalized additive models (GAMs) are developed from 955 U.S. Geological Survey streamflow-gaging stations (streamgages) to predict decadal statistics of streamflow. The streamgages are located on streams draining to the Gulf of Mexico. Decadal statistics include no-flow fractions and selected L-moments of nonzero streamflow for six decades (1950s—2000s). These statistics represent metrics of decadal flow-duration curves (dFDCs) derived from about 10 million daily mean streamflows. The L-moments include the mean, coefficient of L-variation, and the third through fifth L-moment ratios. The models are fit using watershed properties such as basin area and slope, decadal precipitation and temperature...

We depict changing eruptive features within the summit caldera of Kīlauea volcano, Island of Hawaiʻi with rapid-response digital elevation models (DEMs) acquired since a series of caldera-filling effusive eruptions began on December 20, 2020. These eruptions follow the caldera collapse of 2018, with new lava progressively filling the approximately 1-cubic-kilometer pit that formed between May and August of that year. The majority of the provided DEMs were constructed via structure-from-motion (SfM) photogrammetry from either helicopter or uncrewed aircraft system (UAS) overflight images, with the remainder constructed via terrestrial laser scanning (TLS) from the Halemaʻumaʻu crater rim. These data were collected...

This product is a collection of digital data that document fault rupture and ground-deformation features produced by the Ridgecrest M6.4 and M7.1 earthquake sequence of July 4 and 5, 2019. These datasets are described and more fully discussed in Ponti and others (2020) (see External Resources Section below for the full reference). Included in this collection are: GIS Shapefile and KMZ file of field-verified fault rupture and ground deformation features from direct field mapping, or interpreted from ground observations, airborne and satellite optical imagery, digital surface models derived from lidar and structure-from-motion optical image analysis, sub-pixel correlation of multi-temporal optical imagery, and phase...

The U.S. Geological Survey (USGS) Geology, Geophysics and Geochemistry Science Center (GGGSC) collaborated with the USGS Science Analytics and Synthesis (SAS) team to preserve and release a subset of magnetotelluric data from the San Andreas Fault in Loma Prieta, California. The San Andreas Fault data were collected by the Branch of Geophysics, a precursor to the now GGGSC, between 1989 and 1994. The magnetotelluric data selected for this preservation project were collected in 1989 and 1990 using USGS portable truck mounted systems that measure the distribution of electrical conductivity beneath the surface of the earth. Truck mounted systems of this era output data to 3.5” discs, from which data were recovered...
