Summary of Current Disaster Conditions in Vietnam
1. Flood Damage Potential:
LOW IN THE CENTRAL RIVER SYSTEMS AND IN THE SOUTHERN RIVER SYSTEMS
2. Situation Analysis of Flood on Rivers in Vietnam:
(According to Bulletin No. 168DB/TVTNBO, issued by the Vietnam Hydro-meteorological Service in Hanoi at 10:00, 29 November 2003).
CENTRAL RIVER SYSTEMS:
The flood water levels on rivers in the Middle, South of Central Vietnam and in the Central Highlands are reducing slowly.
At 07:00 on 29 November 2003, the flood water levels on major rivers in Central Vietnam were as follows:
- Huong River (Hue Gauging Station - Thua Thien Hue Province): 0.63 meter (0.07 meter above Alarm Level I 0.50 meter),
-Thu Bon River (Cau Lau Gauging Station - Quang Nam Province): 0.71 meter (well below Alarm Level I =2.10 meter).
-Tra Khuc River (Tra Khuc Gauging Station - Quang Ngai Province): 3.20 meter (0.50 meter above Alarm Level I = 2.70 meter),
-Song Ve River (Song Ve Gauging Station - Quang Ngai Province): 2.50 meter (0.40 meter above Alarm Level I = 2.10 meter),
-Kon River (Thach Hoa Gauging Station - Binh Dinh Province): 5.39 meter (0.11 meter below Alarm Level I = 5.50 meter).
On 30 November 2003, the flood water levels on rivers in the Middle and South of Central Vietnam will fluctuate slightly. The flood water levels on rivers in the Central Highlands will change slowly.
SOUTHERN RIVER SYSTEMS:
The upstream flood water level on the Cuu Long River is reducing. On 28 November 2003, the highest flood water level on the Tien River at the Tan Chau Gauging Station was at 2.05 meter (0.95 meter below Alarm Level I = 3.00 meter), and that on the Hau River at the Chau Doc Gauging Station was at 1.89 meter (0.61 meter below Alarm Level I = 2.50 meter),
The upstream flood water level of the Cuu Long River will be reducing.By 03 November 2003, the flood water level on the Tien River at the Tan Chau Gauging Station will be at 1.90 meter (1.10 meter below Alarm Level I = 3.00 meter), and that at the Chau Doc Gauging Station at 1.70 meter (0.80 meter below Alarm Level I = 2.50 meter).
3. Next information:
The next information from the Standing Office of the Central Committee for Flood and Storm Control is expected at 15:00, Sunday, 30 November 2003.

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.
