8 1.2 Mitigation measures and Response Flood forecasting by department of Meteorology and Hydrology (WREA) and the Department of Waterway (Ministry of Public Works and Transport), with technical support from MRCs such as: major tributaries, rainfall data for flood forecasting. Flood protection: levees, gates, drains have been built by the Lao government in major cities located along the Mekong River. (Vientiane, Bolikhamsay, Khammouan, Savannakhet,Champasak provinces).

Collected data by the Provincial Meteorology and Hydrology Office (PMHO) with the assistance from the local people who live close to the stations, the data will later be reported to the DMH in Vientiane Capital. 11

12 2.2 Flood Forecast and Warning System Nearly warning In the case the water level forecast at that station will expect to be at below warning level.

Ensure a nation-wide system of floods mitigation. 13

14 3. Programs and investments Compile statistics data logs on water levels and flow rates. Water drainage construction plan in Vientiane Capital. In Bolikhamsay Province, the construction of locks against floods will continue on most critical tributaries such as Nam San and Nam Kading. 14

Problems and challenges Data and information: flood management and mitigation data have available limited due to data quality system, limited of communication 2. Assistance system (village, required province) Fund for flood Wemanagement: need to support need to improve on flood capacity building of water resources management management, andflood mitigation forecasting capacity system; early warning; mitigation; building, and andalso technical we need support. to improve to drain water system, build a flood protection system due to some area has a low level. Expert and technical support: insufficient; because the flood management of our country to be a new work. Therefore, we have low experience for flood management and mitigation. 15
