Description :
To answer the question whether flooding in South Asia is getting worse and more frequent, all available data were considered: the annual peak discharge data for major rivers, post-1985 information on floods from the global archive of large floods and palaeoflood records from nine Indian rivers. Although there is no significant trend, all types of data point to clustering of large floods. Palaeoflood records show that modern floods (post-1950) have higher flood levels than the late Holocene floods. Notwithstanding the limitations of data, there is enough evidence to conclude that (1) incidences of flood-generating extreme rainfall event are rising and (2) human interventions have made the recent floods more destructive.
