“…A similar pattern of widespread deposition of Late Pleistocene sand and gravel, followed by terminal Pleistocene to Early Holocene fine-grained alluviation culminating in vertical river entrenchment has been documented for the Son and Belan rivers in semi-arid north-central India [90,91] as well as in the sub-humid to semi-arid Murray and Murrumbidgee river basin in southeastern Australia [38][39][40][41][42]. It thus appears that rivers in semi-arid catchments are sensitive to changes in plant cover, whether once glaciated or not.…”

“…More sombrely, during the great El Niño drought of 1877, six million people died in India and some 10 million in China [131]. Since there is substantial overlap between the domain of the monsoon and that of ENSO [90], years of weak monsoon will exacerbate the effect of El Niño-induced droughts, and conversely during La Niña events.…”

River history is reflected in the nature of the sediments carried and deposited over time. Using examples drawn from around the world, this account illustrates how river sediments have been used to reconstruct past environmental changes at a variety of scales in time and space. Problems arising from a patchy alluvial record and from influences external to the river basin can make interpretation difficult. The Nile is treated in some detail because its history is further complicated by tectonic, volcanic and climatic events in its headwaters and by enduring human impacts. It arose soon after 30 Ma. Since that time approximately 100 000 km 3 of rock have been eroded from its Ethiopian sources and deposited in the eastern Mediterranean, with minor amounts of sediment laid down along its former flood plains in Egypt and Sudan. From these fragmentary alluvial remains, a detailed history of Nile floods and droughts has been reconstructed for the last 15 kyr, and, with less detail, for the past 150 kyr, which shows strong accordance with global fluctuations in the strength of the summer monsoon, which are in turn perhaps modulated by changes in solar insolation caused by changes in the Earth's orbit and by variations in solar irradiance.

“…4) there are several metres of reworked tephra, concentrated as a consequence of alluvial processes (Jones, 2010;Lewis et al, 2012;Petraglia et al, 2012). Chronometric ages (OSL) have been obtained for the alluvial deposits within the valley (Williams et al, 2006), although studies disagree on the stratigraphic position of the ash-fall in the sequence (Jones and Pal, 2009;Jones, 2010). Despite the fact that there is an air-fall tephra at Ghoghara, IRSL dating of this section has produced young ages below the ash (Neudorf et al, 2012).…”

“…fluvial, aeolian and colluvial. The OSL technique dates the last daylight exposure of the sediment grains before burial and has been widely used to reconstruct past climate and seismic history with their effect on evolution of early man (Srivastava et al, 2003;Williams et al, 2006;Juyal et al, 2004;Mukul et al, 2007). Using multiple aliquot additive dose protocol (Aitken, 1998), a few luminescence dates on the fault gouges of Himalaya (Singhvi et al, 1994;Banerjee et al 1999), lake sequences (Chamyal and Juyal, 2005) and fluvial terraces of Dun valley has been done (Suresh et al, 2002;Singh et al, 2003).…”

Abstract:Optically Stimulated Luminescence (OSL) dating technique based on the Single Aliquot Regenerative dose (SAR) protocol is being used increasingly as a means of establishing sediment burial age in the late Quaternary studies. Thermal transfer, low and changing luminescence sensitivity of quartz grains of young sedimentary belts of the New Zealand Alps and the north-east Himalaya poses problems in using SAR protocol. Records of active tectonics and signatures of palaeo-climate are preserved in the Quaternary -Holocene terrace sediments. Therefore, to unfold the history of successive tectonic and palaeo-climate events, robust chronological technique is needed. Palaeoflood deposits in NW Lesser Himalayan region receive quartz from the weathering of various rock types such as quartzite and phyllite in the Alaknanda Basin. A series of tests e.g. dose recovery, preheat plateau, thermal recuperation and change in sensitivity, were performed to check the suitability of quartz grains collected from the terrace sediment of Devprayag of the NW Himalaya, for OSL studies. Inferences were drawn regarding the source of the quartz grains on the basis of the geochemistry and luminescence intensity of the terrace sediment. The study shows that though quartz from the North West Himalaya are low in luminescence intensity but the reproducibility of De value makes the quartz sand suitable for SAR dating technique. Relation between luminescence intensity with CIA values help to predict the provenance of quartz sand. Tests show that the quartz from NW Himalaya is suitable for SAR protocol in OSL.
