सारांश	The tsunami shallow water model is a numerical method based on shallow water equations that simulates tsunami wave propagation from earthquake source regions to coastal areas. Developed by Kenji Satake and colleagues in the 1990s, this approach provides rapid estimates of tsunami arrival times, wave amplitudes, and inundation extents for operational early warning systems. The model forms the computational backbone of tsunami warning centers worldwide.	Geostrophic velocity is the current driven by balance between the pressure gradient force and the Coriolis force, derived from the thermal wind equation. In most of the ocean away from the equator and coastal boundaries, geostrophic balance is an excellent approximation to the actual flow. Developed by Harald Sverdrup and colleagues in the 1940s, geostrophic velocity calculation from hydrographic data enables estimation of ocean currents without direct current measurements.
