Morphodynamics

Meandering channels evolve in response to discharge fluctuation in fluvial setting and tidal asymmetry in tidal setting. Understanding of channel morphodynamics is vital to reconstruct facies and stratigraphic architecture of channel deposits in a wide range of depositional environments.

Tidal channels

Tidal channels drain tidal flats and play a vital role in transporting sediments over tidal cycles. As a result, the morphodynamics of tidal channels is important to understand how tidal flat system has evolved under varying environmental conditions including sea-level changes.

River channels

River channels in the fluvial-tidal transition zone evolve in response to discharge fluctuations and tidal prism. The morphodynamics of river channels is a key to understand point bar architecture as well as governing processes. We study abrupt morphodynamic changes and their sedimentary record of the Sittaung River in Myanmar.

Tidal flats

Tidal flat morphology responds to a range of conditions, including tidal currents, waves, seasonal rainfall events, sea-level rise, and anthropogenic forcing. We continue to monitor the morphodynamics of Yeochari tidal flats over the past 18 years. Results indicate that tidal flats are experiencing erosion, and substantial morphological changes have occurred due to channel migration.
