The waves are in the coastal areas on the sandy beds that form on the waves and streams and react. The dynamics of these features are complex, but it is important to understand how coastal morphology can change on this scale.

Dave Et El. [2025] Invest into how the sand and water are treated inside and above these waves. They use modern computer models that combine fluids (using a large edema) and the behavior of the sesame (using a unique particle model) to find out how forces and scanch pressures use a new mathematical method in the bed and differently inside the bed. The numerical procedure does not require the assumptions of the bed boundary layer as needed by other models and is an important new contribution to understanding the transport of coastal sunshine.

Arar from study.
The diagram, which features the numerical model domain, which includes the coordinated system and the related dimensions. There are six sand waves with wavelengths in mobile beds (λr) And height (ηr), Containing spherical sesame particles with diameter (dP) Flow direction to the bed to imitate the influence of surface waves.
