Delta-X River Discharge Surveys in Louisiana Wetlands, 2021

2021-03-25 to 2021-09-25 field measurements of river discharge, bathymetry, and flow velocity in the Atchafalaya and Terrebonne Basins of the Mississippi River Delta floodplain. The dataset was collected by NASA using acoustic Doppler current profilers (ADCPs) on cross-channel transects during spring and fall campaigns. It supports research on wetland hydrology and sediment transport.

Use Cases

• Modeling sediment transport and deposition rates using discharge (m3 s-1) and flow velocity measurements.
• Analyzing seasonal variation in channel bathymetry and flow patterns between spring and fall 2021.
• Calibrating remote sensing data for wetland inundation and water flux studies in the MRD.
• Assessing habitat connectivity and water flow through wide (>100 m) and narrow (~10 m) channels.

Strengths

• Provides measurements from two distinct seasonal campaigns (spring and fall 2021).
• Data collected using professional-grade instrumentation (Teledyne RiverPro and Sontek M9 ADCPs).
• Covers a specific, important coastal study area within the Mississippi River Delta floodplain.

Limitations

• Key metadata such as row count, column names, and exact dataset size are unavailable from all sources.
• A conflict exists in the 'last updated' date between platforms (2026-03 13 on Data.gov vs. 2021 09-25 on NASA Earthdata).
• The license is ambiguously listed as 'other-license-specified' without explicit terms.
