Water is a weakly compressible fluid medium. Due to its low compressibility, it is usually assumed that water is an incompressible fluid. However, if there are high-pressure pulse waves in water, the compressibility of the water medium needs to be consid...

Proper orthogonal decomposition (POD) is used to examine the release of highly concentrated water?sediment mixture in water, with or without ambient current. This technique allows us to extract the dominant features in spatio-temporal data sets and the P...
