Popis:	This study investigates relationship between tsunami flooding flow and spatial distribution of tsunami deposits observed after the December 2004 Indian Ocean Tsunami. Authors first carried out field survey on the south-east coast of Sri Lanka and measured the thickness of tsunami deposits at various sampling locations in the tsunami run-up area. While obtained spatial distributions of sand deposits showed some correlation with well-known parameters such asdistance from the shoreline, some of the data clearly did not support these features. Based on the numerical analysis, weshowed that tsunami back-rushing flow, which locally concentrates on lower ground area, has different flow pattern from the on-rushing flow and well explained the observed spatial distributions of tsunami deposits.
