Vietnamese and American researchers joined efforts to develop a satellite-based system approach to monitor and manage transboundary flooding.

The teams from the Viet Nam National Center for Water Resources Planning and Investigation (NAWAPI) and the University of Washington co-developed and implemented an advanced water forecasting system. Recently, Viet Nam launched the satellite-based system aiming to improve timely access to upstream reservoir information in transboundary river basins of the Red and Mekong rivers. The satellite-based system provides various ways to achieve this objective.

The United Nations Office for Outer Space Affairs (UNOOSA) has activated the International Charter “Space and Major Disasters” for Typhoon Bebinca in Viet Nam, which is expected to make landfall on 17 August. UNOOSA activated the Charter on behalf of the Vietnam Disaster Management Authority.

Meteorologists have forecasted wind speeds up to 90 kph and up to 300mm of rain in the coming days due to the typhoon, bringing the potential for severe flooding and landslides. More than 500,000 people, including soldiers, police officers and civilian volunteers, have been mobilized by Viet Nam’s ministry of defence in order to help civilians in storm-affected areas. Border and coast guards from Quang Ninh down to Quang Binh Province have already ordered... read more

The International Charter: Space and Major Disasters was activated for flooding in Vietnam on 30 July at 16:00 (UTC+02:00). The mechanism was triggered by UNITAR/UNOSAT on behalf of UN ESCAP.

The torrential rain that the northern area of Vietnam has experienced, the heaviest in forty years, started on 26 July and has caused the inundation of thousands of homes and left at least 17 dead.  

“Particularly affected is the Quang Ninh Province on Vietnam's north coast, with cities including Halong, Cam Pha, Uong Bi, Dong Trieu, Van Don and Hoanh Bo all experiencing flooding. In some areas the flood waters have reached 2 metres in height, prompting rescue efforts to evacuate hundreds of residents to safe locations. It is estimated that more than 3000 homes have been affected by the floods,” the Charter informed.

The heavy rain has caused as well landslides... read more
