    sunami sedimentology is a field of Science devoted to the study of the sedimentary features of tsunami deposits. Tsunami inundation (and its associated backwash) promotes changes in the sedimentary balance of a coastal area, typically promoting erosion in the coastal fringe and deposition farther inland. Tsunami sedimentology applies a wide range of sedimentological techniques to identify and differentiate these units in the coastal stratigraphy. These techniques provide data reflecting the characteristics of tsunami waves, transport mechanisms, preservation potential, and sedimentary sources. The identification of tsunami deposits enables estimation of inundation distance and run-up, although patterns of erosion and deposition by both landward- and seaward-directed flows introduce uncertainties in those reconstructions. Examination of palaeotsunami deposits leads to inferences on the recurrence intervals of extreme events in the coastal zone and improves hazard planning and mapping
