This paper investigates the complex interaction between wave hydrodynamics and aquatic vegetation, emphasizing its importance for management of coastal ecosystems. Vegetation plays a crucial role in dynamics river flows, influencing their structure turbulence, as well transport distribution nutrients, sediments, ecosystems, habitats. For example, mangroves serve natural defense against tsunamis extreme waves. Nature-based technologies are increasingly being adopted, alignment with principles...

The present study investigates bubbly two-phase flow in a hydraulic jump using visualization technique. Bubbly is encountered many engineering problems; however, mainly because of experimental difficulties, little known on the internal structure these flows, although such knowledge clearly essential to thorough understanding mass transfer between two component phases. In past, some authors measured distribution void ratio hot-film anemometry. Nowadays this interesting technique may be...
