Brahmaputra River Bathymetry and Seismic Surveys from 2013-2014

A 2013 and 2014 river multibeam and seismic survey collected data at scour sites within the Brahmaputra river basin in Bangladesh. The survey was part of a joint project between the Universities of Birmingham, Southampton, and Exeter, funded by NERC grant NE/I023228/1. The purpose was to collect data to validate the first generic numerical model of scour zone stratigraphy for large rivers.

Use Cases

• Validate numerical models of scour zone stratigraphy based on the collected multibeam and seismic data.
• Analyze riverbed morphology and sediment structure based on bathymetry and sub-bottom profiling.
• Study the sedimentology of channel confluences based on data accepted for a 2018 publication in 'Sedimentology'.

Strengths

• Data collected during a dedicated scientific survey in 2013 and 2014.
• Multibeam echosounder and surface tow boomer/chirp systems used for data collection.
• Data was accepted for a peer-reviewed publication in the journal 'Sedimentology' in 2018.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Data may reflect geographic and temporal bias specific to the Brahmaputra basin in 2013-2014.
