I-Background of Proposal:
Mekong River is a life line to Cambodian. Mekong is extended from the North toSouth about 480km by crossing 5 provinces: The Mekong and its tributaries
combined with local rainfall, annual flood 17,100sqkm or 25% of plain area of basin.
Heavy rains during slow moving storms aggravated by large-scale deforestation
also result in flashflood, The Mekong river flows frequently overtop its banks due
to high rainfall in the basin causing flood in low land provinces. The flood areaaround Phnom Penh, a capital of Cambodia, and down to Viet Nam border is about
7,000km2. Province prone to the Mekong flood are StungbTreng, Kratie, Kampong
Cham, Kandal, Prey Veng and Svay Rieng.
The flood in 2000 was reportedly the worst in more than 70 years, The official
report compiled by National Committee for Disaster Management(NCDM) on 16
November 2000, put the death toll 374 persons(80% of whom were children). Of the750,618 families (3,448,629 individuals) affected by flooding in 21 provinces ormunicipalities, about 85,000 families (387,000 individuals) had to be evacuated.
Furthermore 317,975 houses were damaged, while 7,068 were destroyed,
Approximately 688,021 ha of consumption and cash crop were damaged. Base on
this NCDM report estimated total physical and direct damage at US$ 157 million,
in 2001 flood damage in Cambodia was estimated US$36 million.
It is recognized that in the Lower Mekong basin, flood are recurring events,providing abundance of fish and wealth of biodiversity to the region, water supply,navigation, route, fertile sediment for agricultural land. But, at the same time, theMekong flood cause loose of lives and properties as well as disruption of social
economic activities destroy infrastructures throughout basin. Therefore, any flood
mitigation measures, intervention, policies or plan undertaken should take thepositive aspect of flood in to accounts to insure the sustainable development incountry while protective lives and properties from flood damage.
Past activities related to flood disaster management have been mainly focusing onrelief operation. According to the past experiences show that the effective
implementation of flood preparedness programs at local levels could help people
better cope with serious flood events and thereby avoid unnecessary damage
through various measures.
II-Outline of Target area:
Prey Veng province is located in the floodplain of the Mekong and Tonle toch . Mostof the area of province are vulnerable to flood from Mekong and its tributaries.

Prey Veng consists of 12 districts, 116 communes, 1,317 villages. Its shares borderwith Kaompong Cham in the north, Svay Rieng in the east, Kandal in the west andwith Veit Nam in the south. The total land area is about 488,300 km2, with thepopulation of 1,103,703 persons(2006),and divided into two mainareas:
Low lying area: This area located in
the west part of th province, extend
along the Mekong and Tonle Touch
rivers, where Tonle Touch spansfrom north to south across 5
districts, this area lies in theMekong delta and is rich withnutrients and suitable for growing
rice in wet and dry seasons, fishing and additional cropping.
Highland area: it is in the eastern part of the province and also made up of old
alluvial sandy soil, contains poor nutrients, and is suitable for wet season rice only.
This area always faces drought, water shortage that has serious effects on
livelihoods of local people.
Part of Mekong river 75km flows across Prey Veng visa two districts (Peam Chor& Peam Ro), beside the Mekong river, there are three tributaries of Tonle Toch
(Small river) total 230km flows across seven districts in Prey Veng Province.
According to the annual report of the Provincial Committee for Disaster
Management (PCDM), all damage losses including human lives, Infrastructure andsocial economic impact in the affected area for the above mentioned are below:

V-Expected Effectiveness:
The goal of the flood management is to minimize the damage of life and property
from disaster of flood. Flood hazard map is considered as a useful tool to mitigate
the impact of flood disaster, promote of safe and smooth evacuation in flood prone
area is very important, because in case if serious flood occurs, the causality will beun-expectable. Flood hazard map can be a great help to aware people and to assist
their evacuation in need.
