Zusammenfassung |
Solitary wave runup on a non-plane beach is studied analytically and
numerically. For the theoretical approach, nonlinear shallow-water theory is
applied to obtain the analytical solution for the simplified bottom
geometry, such as an inclined channel whose cross-slope shape is parabolic.
It generalizes Carrier-Greenspan approach for long wave runup on the
inclined plane beach that is currently used now. For the numerical study,
the Reynolds Averaged Navier-Stokes (RANS) system is applied to study
soliton runup on an inclined beach and the detailed characteristics of the
wave processes (water displacement, velocity field, turbulent kinetic
energy, energy dissipation) are analyzed. In this study, it is theoretically
and numerically proved that the existence of a parabolic cross-slope channel
on the plane beach causes runup intensification, which is often observed in
post-tsunami field surveys. |
