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 2, 2017, to document the CSA pin elevations, cross section geometry at the CSA sensor locations, and high-water marks from the flow event.
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.
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. A flow event occurred on July 28, 2017. Stage data were recorded by submersible pressure transducers at each of the four cross sections. The stage data, along with cross section geometry and field-assigned roughness values, were used to compute discharge for the flow event using the CSA method.
The dataset consists of a slope-area computation of peak discharge (published via NWIS), stage data from continuous slope-area (CSA) sensors, CSA computations of discharge data, verified Manning's roughness coefficients (n), channel geometry and reach properties associated with Manning's n computations, and GPS survey data associated with the flow event on July 28, 2017, at 09471143 - Walnut Gulch below ARS Flume 6, near Tombstone, AZ.
