09471143 - Walnut Gulch below ARS Flume 6, near Tombstone, AZ - 07/28/2017 Manning's n Verification

Continuous slope-area (CSA) sensors are installed at four cross sections downstream from Flume 6 operated by the Agricultural Research Service (ARS) at the Walnut Gulch Experimental Watershed. Stage data were recorded by submersible pressure transducers at each of the four cross sections, which is used to compute channel roughness using the known discharge measured by Flume 6.

09471143 - Walnut Gulch below ARS Flume 6, near Tombstone, AZ - 08/02/2017 GPS Survey

Continuous slope-area sensors are installed at four cross sections downstream from Flume 6 operated by the Agricultural Research Service (ARS) at the Walnut Gulch Experimental Watershed. The CSA reach was installed to test the CSA method and determine channel roughness using the known discharge measured by Flume 6. A flow event occurred on July 28, 2017. A GPS survey was conducted on August...

Controlled source audio-frequency magnetotellurics (CSAMT) data from the Big Chino Wash and Paulden areas, Yavapai County, Arizona

Controlled source audio-frequency magnetotellurics (CSAMT) data were collected in the Big Chino Valley and Paulden areas, Yavapai County, Arizona, to better understand the hydrogeology of the area. CSAMT data provide vertical cross-section (profile) data about the resistivity of the subsurface, which may be related to lithologic boundaries and (or) grain-size distribution in the subsurface....

High-Water Mark Survey of July 10, 2018, Flood at I-10 Frontage Rd at Twin Peaks Rd, Marana, AZ

A train derailment occurred in Marana, Arizona, on July 10, 2018. Runoff from a severe thunderstorm was flowing over the tracks at the time and may have contributed to the derailment. At the request of the Pima County Regional Flood Control District, USGS collected high-water marks for the flood event upstream from the derailment area.

Supplemental discrete dissolved-solids and specific conductance data and monthly mean dissolved-solids load data in the lower Colorado River, 1928-2016

Monthly Mean Dissolved-Solids Concentration and Monthly Mean Dissolved-Solids Load Data Flow weighted monthly mean dissolved-solids concentrations (mg/L) data and monthly mean dissolved-solids load data from 1928-2016 were computed by USGS using raw data from the Bureau of Reclamation. These data were computed by USGS for all of the seven sites (listed below). Colorado River above
