Nodal and modal spectral element and compact methods are used to obtain solutions for engineering problems such as particle-fluid interactions in two-phase flows, sediment particles transport and entrainment in shear flows, and fluid resistance induced by flexible vegetation stems (simulated as bendable rigid cylinders) for flood risk reduction in wetlands along the coast. In addition, Boussinesq equations simulating nonlinear water waves in coastal and ocean engineering are solved with a high order compact method. The accuracy of results is demonstrated and efficiency of methods is discussed.
