About article:
Dams have an important role in the industrial development of countries. Irrespective of the reason for dam
break, the flood can cause devastating disasters with loss of life and property especially in densely populated areas. In
this study, the effects of the vegetation on the flood wave propagation in case of dam break were investigated experimentally
by using the distorted physical model of Ürkmez Dam. The horizontal and vertical scales of the distorted physical
model are 1/150 and 1/30, respectively. The dam break scenarios were achieved by means of a gate of rectangular and
triangular shape. The results obtained from experiments performed with vegetation were compared and interpreted with
those obtained from experiments at which the vegetation configuration was absent. The analysis of the experimental data
showed that the presence of vegetation causes a significant decrease in water depths as the flood wave propagates to the
downstream and greatly reduces its impact on the settlements. It is also revealed that dam break shape plays an important
role in temporal variation of flood wave.
