Data

This dataset represents the network-adjusted results of relative- and absolute-gravity surveys. Relative-gravity surveys were carried out using a Zero Length Spring, Inc. Burris relative-gravity meter. The effect of solid Earth tides and ocean loading were removed from the data. Instrument drift was removed by evaluating gravity change during repeated measurements at one or more base stations. Abs

This USGS Data Release represents water and sediment quality data collected in the Grand Canyon region of northern Arizona. There are 4 separate datasets associated with this Data Release: Water quality data from major Colorado River tributary monitoring sites in and near Grand Canyon from 2015 through 2022. Sediment quality data from the Colorado River and major tributary monitoring sites in an

This is a terrestrial LiDAR laser scanner dataset of an intermittent waterway named Laguna Creek near the community of Dennehotso, AZ collected on June 2, 2020. The reach scanned for this study is located at the bridge where State Route 160 crosses the waterway. The river channel on the upstream side of the bridge has experienced bank erosion over recent years. A bank stabilization project was imp

The dataset contains GPS survey data of ground control points deployed for aerial LiDAR data collection. The targets were deployed and surveyed on 8/12/2020 and the LiDAR flight was conducted on the morning of 8/13/2020. The control points were surveyed using Leica GS14 RTK GPS equipment, S/N rover-2806883, using the Real Time Network, Leica Smartnet, to determine absolute position.

These data were compiled to accompany flow modeling work on Little Colorado river above the mouth (USGS gage 09402300). The data include example models in FaSTMECH and SToRM solvers in the iRIC framework, topographic data collected by LiDAR and total station in June 2017, and high water marks from nine historic floods. Other data also include location and other information for control points and g

The dataset contains GPS survey data from two surveys conducted after a flow event on February 15, 2019, at the USGS continuous slope-area (CSA) gage 09484201 - Bear Creek above Bear Canyon Road, near Tucson, AZ. The CSA gage is located downstream from Pima County Regional Flood Control District ALERT gage 2184 - Bear Canyon Wash near Bear Canyon Rd. The first survey, on February 19, 2019, documen

A GPS survey was conducted on July 10, 2018, to document the CSA pin elevations and cross section geometry at the CSA sensor locations at CSA 09471587 - Dragoon Wash above San Pedro River at St David, AZ, and CSA 09471588 - San Pedro River below Dragoon Wash at St David, AZ. Three CSA pin elevations and cross sections were surveyed at CSA 09471587 - Dragoon Wash above San Pedro River at St David,

The dataset contains data from a GPS survey conducted after a flow event on November 29, 2019, at the USGS streamgage 09471580 - San Pedro River at St David, AZ. The survey, conducted on December 5, 2019, documents cross section geometry and high-water marks from the flow event in the reach downstream from the gage. One CSA pin elevation at CSA 09471588 - San Pedro River below Dragoon Wash at St D

A GPS survey was conducted on June 12, 2019, to document the cross section geometry at the streamgage 09471580 - San Pedro River at St David, AZ, and CSA pin elevations and cross section geometry at the CSA sensor locations at CSA 09471588 - San Pedro River below Dragoon Wash at St David, AZ. One cross section was surveyed at streamgage 09471580 - San Pedro River at St David, AZ; and four CSA pin

This dataset represents the network-adjusted results of relative- and absolute-gravity surveys. Data are provided in tabular (csv) and vector (shapefile) formats with one row per station.Relative-gravity surveys were carried out using a ZLS Coporation Burris relative-gravity meter. The effect of solid Earth tides and ocean loading were removed from the data. Instrument drift was removed by evaluat

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

Water quality parameters (water temperature, specific conductance, pH, dissolved oxygen, air temperature, and barometric pressure) were measured in the Verde River over a half mile reach below the confluence with Granite Creek. Measurements were made using a calibrated In-Situ SmarTROLL multiparameter meter on June 13, 2018.
