Summary

The dataset contains GPS survey data from two surveys conducted after a flow event on September 19, 2018, at the USGS streamgage 09487000 - Brawley Wash near Three Points, AZ. The first survey, on October 1, 2018, documents cross section geometry and high-water marks from the flow event in the reach downstream from the gage. The second survey, on January 31, 2019, documents additional high-water marks and provides ground control for a small unmanned aircraft system survey. The surveys were performed using Leica GS14 RTK GPS equipment, S/N base-2806898, S/N rover-2806883.

Purpose

Gage height and discharge data are collected at U.S. Geological Survey streamgage 09487000 - Brawley Wash near Three Points, AZ. A flow event occurred on September 19, 2018. A GPS survey was conducted on October 1, 2018, to document cross section geometry and high-water marks from the flow event. A second GPS survey was conducted on January 31, 2019, to document additional high-water marks and to provide ground control for a small unmanned aircraft system survey. The data were collected to compute peak discharge for the September 19, 2018, flow event using the slope-area method and to compare to data collected during the small unmanned aircraft system survey.
