India: Flooding forces rail disruptions in Delhi; thousands evacuated /update 8

Event

Approximately 10,000 people in Delhi evacuated to higher ground in the past several days as the Yamuna River continued to rise as of Monday, July 30. The floodwaters forced the closure of the old Yamuna rail bridge on Sunday night (local time), July 29, causing passenger train disruptions. The bridge is the main link between Delhi and neighboring states to the east.

The river level has remained above the flood danger stage for three consecutive days, reaching a height of 205.8 meters (675 feet) on Monday evening, and is expected to peak around 206.5 meters (677.5 feet) by Wednesday, August 1. The flood danger stage is set at 204.83 meters (672 feet). Water is also being released from the upstream Hathani Kund dam to alleviate pressure on the dam, which will keep water levels in Delhi high.

Context

The Yamuna River is a major tributary of the Ganges River. It flows from the Lower Himalayas in Uttarakhand state and later along the eastern side of New Delhi. It is one of the most polluted rivers in the world, partly due to large amounts of sewage and waste that empties from India's capital. Recent heavy monsoon rains in northern India has swelled rivers and reservoirs in the region, causing flooding and leading to the deaths of at least 64 people. Further rains and flooding is possible throughout the remainder of the monsoon season, which runs from June through September.

Advice

Individuals present in the aforementioned areas are advised to monitor weather forecasts, refrain from traveling to flooded areas, and follow any instructions issued by local authorities. Remember that driving or walking through running water can be dangerous - 15 cm (6 in) of running water is enough to knock over an adult - and that floodwater may contain wastewater or chemical products; all items having come into contact with the water should be disinfected and all foodstuffs discarded. Be aware that the risk of contracting water- and mosquito-borne diseases tends to rise after periods of heavy rain.
