IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

ABSTRACT
Vegetation such as mangroves and saltmarshes plays an important role for coastal protection. However the mechanism
to dissipate energy is not clear yet. One of the reasons is due to the lack of knowledge about drag coefficient. Hence, a
numerical model can be useful to study the basic mechanism. In this study, an applicability of the SPH-based
DualSPHysics model to derive drag coefficient in vegetation using a simple case is explored. The obtained Strouhal
number, cross flow magnitude and drag coefficient are compared to the values in literature. Numerical outputs in
DualSPHysics are in good agreement with the values in literature. Preliminary results show the capacity to apply the
DualSPHysics model to the derivation of drag coefficient in vegetation.
