摘要: Abstract In this paper we identify changes in the Indian Summer Monsoon (ISM) intensity during late Holocene as revealed by palaeohydrological proxies fluvial archives of western India. Proxy indices, including geomorphological, sedimentological, geochemical and biological evidence along with chronology have been employed to highlight trend ISM over Holocene. It is inferred that on a longer timescale, weakened however; short pulses ameliorated monsoon occurred around 3, 1.6 0.3 cal ka BP. Clustering flood events seen occur at 3–2.8, 2.2–1.6, 1.3–1.1 0.65–0.2 cal BP not necessarily coinciding strengthening ISM. Palaeoflood data regard variability shows two most prevalent 0.5 1.7 cal coincide weak period/climatic transition region. The occurrence high magnitude periods also reflected modern rainfall data. surmised may represent peak however, cannot be singularly considered indicators for enhanced conditions Only more robust database can further validate their implications monsoonal
