A continuous record of the largest Narmada floods over the last 2000 years was obtained from Sakarghat, on the Narmada River from a study of slackwater flood deposits. Two sequences of extreme floods date between ca. 400 and 1000 AD and post-1900 AD. The period, 400-1000 AD representing a period of less frequent but more extreme floods, has been documented in the archaeological record as one of decline of human settlements.- Palaeofloods and Global Change

A great weakness of various intenational scientific initiatives global change, earth system science and related hydrological assessment of flood hazards is their overemphasis on prediction from idealized conceptual models. The latter are abstract constructs made possible by rapidly increasing computer power but predicated upon often unverified and sometimes unverifiable assumptions. It is now realized that abrupt climate change and extreme events pose more of a global change hazard than do the mean climate phenomena predicted by global climate models (GCMs). For 20 years there has been an overemphasis on developing these models as the principal tool for dealing with threats to habitability of the planet. In contrast to unverified predictions of the future given by GCMs, palaeoflood data provide evidence of Real-Work cataclysms that people can understand sufficiently to alter their perceptions of hazards, thereby stimulating appropriate action toward mitigation. This issue is particularly important in the world's tropical monsoon areas, which are prone to especially extreme floods and high variability in their magnitude and frequency. These areas, which are inhabited by half of the Earth's human population, also have excellent sources of palaeoflood information, which comprise a natural archive that can appropriately stimulate productive hazard reduction.Keywords
