《Centrifugal model tests and numerical simulations for barrier dam break due to overtopping》
Note:=fluid density,=dynamic viscosity,hd=dam height,ld=dam length,md=slope coefficient of downstream,V/H=vertical length/horizontal length,b0=initial breach width,zb0=initial breach bottom height,n=Manning coefficient,d50=median size of soil,G
In addition,ρm=ρp(ρm,density of prototype materials;ρp,density of model materials)in the centrifugal model tests;therefore,it is necessary to ensure that the model dam has the same dry density as the Tangjiashan landslide dam,whose value is 1.59 g/cm3.The basic parameters of the model dam material are shown in Table 1.
