Реферат: | eng: Works on improvement the assessment of tsunami manifestation off the coast necessitated the creation of methods, algorithms and software for the simulation of tsunami runup on coastal zone to determine the flood zone, the distribution of flow rates maximum depths and duration of flooding.
One of the key requirements for this toolbox is the ability to use it in a real water areas with sharply varying bathymetry, greatly changing steepness of terrain adjacent to the shore line, irregularity of "water-land" border.
The authors examined various approaches, including techniques based on the use of analytically given boundary conditions, methods of extrapolation and algorithms of through calculation. According to the tests’ results the method of large particles, proposed in [1], was chosen as the basic algorithm.
The results presented in the report are related to the investigation of the behavior of tsunami waves near the two parts of the coast of the Far East of Russia - in the vicinity of the Severo-Kurilsk town (Fig. 1) and Malokurilskaya Bay (Fig. 2).
The authors considered the model tsunamis generated by hypothetical tsunamigenic earthquakes, the sources of which were calculated using the dislocation model of Podiapolsky-Gusyiakov-Okada. The processes of waves propagation over the ocean and runup on the shore are modeled within the framework of the shallow water equations. The wave runup is calculated using specialized design module that performs the modeling of tsunami runup on the detailed computational grids covering the pre-selected parts of the coastal zone. The exchange of information with the domain of modeling of wave propagation from the source to the coastal zone is carried out through the boundaries. The results are compared with the known data of field observations.
