DISASTER SITUATION REPORT TO UNDP RESIDENT REPRESENTATIVE
Prepared by: UNDP/MARD - DISASTER MANAGEMENT UNIT, VIE/97/00215:00 Tuesday, 06 July, 2004Summary of Current Disaster Conditions in Vietnam
1. Flood Damage Potential: LOW IN THE NORTHERN, CENTRAL AND SOUTHERN RIVER SYSTEMS
2. Situation Analysis of Flood on Rivers in Vietnam:(According to Bulletin No. 37DB/TVBBO and Bulletin No.26DB/TVTNBO , issued by the Vietnam Hydro-meteorological Service in Hanoi at 14:00, 05 July 2004).
NORTHERN RIVER SYSTEMS:
The Red River System:
The flood water levels on downstream rivers of the Red river system are decreasing slowly. At 7:00 on 05 July 2004, the flood water level on the Red River System at the Hanoi Gauging Station (Hanoi City) was at 4.78 meter.
The Thai Binh River System:
The Thai Binh River System?s downstream flood water level is at low level and subjected to tidal impact. At 7:00 on 05 July 2004, the flood water level at the Pha Lai Gauging Station (Hai Duong Province) was at 1.79 meters (1.71 meter below Alarm Level I = 3.50 meters).
CENTRAL RIVER SYSTEMS:
The flood water levels on rivers in provinces of Thanh Hoa and Binh Thuan and in the Central Highlands are reducing slowly . At 07:00 on July 05, 2004, the flood water level on Ma River (Giang Gauging Station ? Thanh Hoa Province): -1.09 meter (much lower than Alarm Level I = 3.50 meters), on La Nga River (Ta Pao Gauging Station ? Binh Thuan Province): 118.36 meter (0.64 meter lower than Alarm Level I = 119 meter), on Srepok River (Ban Don Gauging Station ? Dak Lak Province): 168.52 meter ( 1.08 meter lower than Alarm Level I = 169.60 meter), on Ca Ty river (Muong Man Gauging Station ? Binh Thuan Province): 2.22 meter (1.78 meter lower than Alarm Level I = 4 meter).
SOUTHERN RIVER SYSTEMS:
The Mekong River?s upstream flood water level is increasing slowly. On July 04, 2004, the highest flood water level in the Tien river at Tan Chau gauging station was at 1.56 meter, on the Hau river at Chau Doc Gauging Station was at 1.45m.
3. Next information:
The next information from the Standing Office of the Central Committee for Flood and Storm Control is expected at 15:00, Wednesday, July 07, 2004.

Distinction of river flood alarm levels:
Alarm Level I - Possible flood condition - River water level is high; threat to low height embankments; flooding of very low lying areas; infrastructure safe.
Alarm Level II - Dangerous flood condition - Flood plane inundation expected; towns and cities still generally protected by flood defences; high velocity River flows pose danger of bank and dyke erosion; bridge foundations at risk from scour; infrastructure generally safe.
Alarm Level III - Very dangerous flood condition - All low lying areas submerged, including low lying areas in cities and towns; safety of River protection dykes in jeopardy; damage to infrastructure begins.
Alarm Level III + Emergency flood condition - General and wide spread uncontrollable flooding; dyke failure a certainty and probably uncontrollable; damage to infrastructure severe.
