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.
Using small unmanned aircraft systems for measuring post-flood high-water marks and streambed elevations
Floods affected approximately two billion people around the world from 1998–2017, causing over 142,000 fatalities and over 656 billion U.S. dollars in economic losses. Flood data, such as the extent of inundation and peak flood stage, are needed to define the environmental, economic, and social impacts of significant flood events. Ground-based global positioning system (GPS) surveys of post-flood
Reach-scale monitoring and modeling of rivers--Expanding hydraulic data collection beyond the cross section
For over 125 years, the U.S. Geological Survey streamgage network has provided important
hydrologic information about rivers and streams throughout the Nation. Traditional streamgage
methods provide reliable stage and streamflow data but typically only monitor stage at a single location in a river and require frequent calibration streamflow measurements. Direct measurements are not always feasible
Continuous slope-area discharge records in Maricopa County, Arizona, 2004–2012
Continuous slope-area (CSA) streamgages have been developed and implemented by the U.S. Geological Survey (USGS) to enable the recording of discharge hydrographs in areas where direct discharge measurements cannot be made. The flashy nature of streamflow in parts of the arid Southwest and remote location of many sites make discharge measurements difficult or impossible to obtain. Consequently, ava
