Ganges-Brahmaputra Delta Fieldwork

Exploring the coastal mangrove forests and agricultural region in the Ganges brahmaputra delta. Tidal flows bring new mud regularly to sustain the natural delta plain. We are modeling the tidal flow and sedimentation patterns and here are trying to assess how much effect mangrove roots, and small channels in the protected areas have on the flow patterns. Over the last few years fieldworks we worked with colleagues of VanderBilt, UT Austin, LSU and Old Dominion to collect sedimentation rate measurements, channel bathymetric data. Newly installed CTD and turbidity sensors will further enlighten us on the complex system dynamics in this entangled delta neltwork. A sister project is in collaborattion with local engineers and helps set new designs for coastal protection.
