Pre-Delta-X: River Discharge Channel Surveys across Atchafalaya Basin, LA, USA, 2016

Description

This dataset provides river discharge measurements collected at selected locations across the Atchafalaya River Basin, within the Mississippi River Delta (MRD) floodplain in coastal Louisiana, USA. The measurements were made during the Pre-Delta-X campaign on October 15 to 20, 2016. Seventy-five channel surveys were conducted with a SonTek RiverSurveyor M9 acoustic doppler current profiler (ADCP) on selected wide channels (~100 m) and a few selected (~10 m) narrow channels. ADCP data provide near-instantaneous estimates of river discharge across the sampled channels. Sites coincided with AirSWOT swaths in the Atchafalaya River Basin and water level measurement locations. This in situ dataset was used to calibrate and validate Delta-X hydrodynamic models.

34 Measurement of river discharge across channels. The acoustic doppler current profiler (ADCP) was mounted on a hydro board, which was allowed to drift alongside the boat while maintaining a transect perpendicular to flow. The impact from the boat was limited by slowly crabbing across each channel, allowing the ADCP to remain on the upstream side of the boat. https://daac.ornl.gov/DELTAX/guides/PreDeltaX_ADCP_Measurements_Fig1.png
