Flash floods in the context of "Gobi Desert"

In geography and geology, fluvial sediment processes or fluvial sediment transport are associated with rivers and streams and the deposits and landforms created by sediments. It can result in the formation of ripples and dunes, in fractal-shaped patterns of erosion, in complex patterns of natural river systems, and in the development of floodplains and the occurrence of flash floods. Sediment moved by water can be larger than sediment moved by air because water has both a higher density and viscosity. In typical rivers the largest carried sediment is of sand and gravel size, but larger floods can carry cobbles and even boulders.When the stream or rivers are associated with glaciers, ice sheets, or ice caps, the term glaciofluvial or fluvioglacial is used, as in periglacial flows and glacial lake outburst floods. Fluvial sediment processes include the motion of sediment and erosion or deposition on the river bed.

Operation Surya Hope was the Indian Army’s Central Command response to the June 2013 North India floods in Uttarakhand.

The Uttarakhand flood was caused by record off-season monsoon rains, cloud burst, floods, flash floods, and glacial lake outburst floods (GLOFs), which were possibly induced by climate change. The humanitarian disaster affected millions, stranded over 100,000 pilgrims and tourists in Himalayan religious sites, and killed several thousand people.The Indian Army's Lucknow based Central Command conducted the operation. Surya or Sun, is the emblem of the Central Command and features prominently on the Command's formation sign and flag, which is probably why Central Command chose to name the effort Operation Surya Hope.
