| Popis: | The 2014 extreme flooding in Kashmir, with the peak discharge exceeding 115,000 cfs and the Jhelum River overflowing its banks, was triggered by the complex interplay of atmospheric disturbances causing widespread extreme rainfall for 7 days preceding the event. We used multisource data in GIS environment; satellites, hydro-meteorological, socioeconomic and field data, to assess the role of various factors in the flooding. The event was aggravated by the geomorphic setup of the Valley. Tributaries in the south, characterized by high gradient, decreased time of runoff concentration and increased flood peakedness with short lag, almost simultaneously discharge enormous volumes of floodwaters into the Jhelum around Sangam. Owing to the flat gradient of the Jhelum from Sangam downstream ( |
