ABSTRACT The Xebangfai river is one of the main tributaies of the Mekong river The Xebangfai basin mainly covers two provinces namely Khammouan and Savannakhet which frequency affected by flooding which caused from heavy rainfall together with Mekong water rising up In order to provides the better understanding about flooding hazard and potential damage, this study aim to develop the innundation map in downstream of Xebangfai river and the result is very usefully for decision-making and provides the mitigation procedurce in lower Xebangfai basin The flood frequency analysis was done by using Pearson Type III distribution method to obtain a maximum total rainfall in days for years, 10 years, 50 years, 100 years and 200 years return period then construct design hyetographs base on the recorded data The NAM and MIKE 11 models were calibrated and verified by using the periods floods data Then the floods simulation and inundation maps were done for different return periods in order to determine the flood for flood procedure were carried out in order to reduce the negative effects of floods Mangh■■ng Luôn 123doc Th■a thu■n l■icam s■ tr■ h■u k■t s■ nghi■m t■im■t d■ng

Inventory system with their synchronization at all levels while encouraging decentralized approaches - Expansion and digitalization of existing hydro-met stations throughout the country; - Establishment of the Early Warning Center and National Emergency Operation Center; - Establishment of basic disaster database and inventory system and networking; Pay more attention on Disaster Risk Reduction in some areas of national critical infrastructure; especially, industrial park, and special and specific economic development zone - Promotion and development of building codes for infrastructure construction in key sectors - Promotion of physical urban planning by integration of disaster risk factor; reduction and climate change adaptation in sectorial development - Promotion of natural resources planning and conservation as effective tools for natural disaster buffer; The case of investing in disaster risk reduction needs to be brought attention of strategic planning and financing managers utilize more research around the economics of disaster and approach of private sector - Improvement of common education curriculum on surrounding environment with more DRR integration; - Undertake drills in some risky schools and communities - Development and integration of disaster curriculum at university and high education level; - Supporting more research topics on disaster and climate change; - Development of disaster management command course for policy makers and governors; Promoting socialization of risk reduction as “everybody’s job”; special attention to

most province which usually affected from big floods at many areas in the Xebangfai basin In this province, the socio-economic condition is developing for a quality of life in community It is necessary to have a plans and preparedness for reducing the floods damages So, the flood inundation and flood hazard for different return periods of flood are considered in this basin This study can be summarized as follows: Using the data of rainfall and discharge collected at various stations in the study area, Person type III distribution is used for frequency analysis The maximum of total rainfall in days corresponding to 200 year, 100 year, 50 year, 10 year and year return period are determined at Mahaxay, Banhay, Boualapha, Xaibouthong and Xebangfai corresponding to various return periods are also determined The design hyetographs in each station are determined based on typical distribution of actual rainfall So, more past data should be considered in order to choose the best design hyetographs Using NAM model, which was calibrated and verified for rainfall-runoff with input of hyetographs between at Mahaxay and Xebangfai Bridge no 13 station were done The parameters of NAM model for each sub-basin were determined The correlation coefficient (R) in all case of calibration and verification NAM model are higher than 0.94, and the different of peak is less than 5% In addition, the results obtained from NAM model show that the simulated discharge hydrographs cannot fit the observed hydrographs for all of calibration periods, due to the parameters should be adjusted or determined based on the recently observed data The computed design hydrographs at these stations are the upstream boundary conditions for simulating flood flow in MIKE 11 model In study area, discharge at Mahaxay station is the upstream boundary condition and water level at outlet of Xebangfai river is the downstream boundary condition of hydrodynamic model (MIKE 11) MIKE 11 model is calibrated and verified with the 76 da da i ho da i ho c da i ho c th da i ho c th uy da i ho c th uy loi da i ho c th uy loi da da i ho c th uy loi da i ho da i ho c th uy loi da i ho c da i ho c th

observed and simulated water level at Tohen station are less than 0.3% In addition, the correlation coefficient(R) of calibration and verification is higher than 0.97% and efficient index (EI) is higher than 0.95% at station The result shown that the parameter of MIKE 11 for Xebangfai river basin can be used for simulating design flood flow in river network So the water level hydrographs corresponding to different return periods at various stations are determined based on the assumption that the return period of rainfall in upstream and return period of water level at downstream boundary of the model are the same Based on the computed water level hydrographs from MIKE 11 model and ground Digital Elevation Map (DEM) of 90 x 90 meter resolution in Xebangfai basin, inundation maps for various return periods of flood and developed by MIKE 11-GIS model The accuracy of inundation maps was checked by flooding depth and extent of flooding at some locations The total submerged areas for various intervals of flooding average from 397994.3 to 397999.17 of the total area in NongBok District In case, the return period of flooding is equal or less than or less than 50 years (T≤50 years), most of area having flooding depth are less than 5.0 meter, while maximum of flooding depth can be up 7.0 meter For constructing flood hazard map, due to limitation of data, this study considered the flood of 10 year return period Flood hazard map is developed based on flooding depth and flooding duration Four categories of flooding depth (below 0.5 meter, 0.5 to 1.5 meter, 1.5 to 3.0 meter and above 3.0 meter) and flooding duration (under days, to 25 days and above 25 days) is determined For the hazard assessment in return period 200 year, 100 year, 50 year, 10 year and year, there show the percentage of area at each hazard level such as 21.90% at low level, 23.97% at medium level, 23.08 at high level and 31.05 at very high level For mitigation procedure, there are four components of Disaster Risk Management such as prevention, response, preparedness and reconstruction In procedure during implementation are damage and loss assessment, post disaster need assessment, creating the planning action of activities 77 da da i ho da i ho c da i ho c th da i ho c th uy da i ho c th uy loi da i ho c th uy loi da da i ho c th uy loi da i ho da i ho c th uy loi da i ho c da

return periods of flood determined can be useful for constructing embankment system, infrastructure, buildings improvement, and the warning of possible flooding Maximum of water level corresponding to different return periods were determined at various location along the rivers and floodplains by using the model which were calibrated and verified in this study Flood duration in river may occur in a week, while flooding duration in floodplains can be up to one month For Hazard assessment, the combined effect of flood depth and flood duration is considered by weighting factors for both depth and duration of flooding Flood hazard map was developed typically for the flood of 10 year return period The levels of hazard determined for community in NongBok district Integrating of disaster risk reduction and climate change adaptation into for sustainable development All inundation maps different return period and hazard level map at NongBok district is very usefully tool for flood management Recommendation Discharges at Mahaxay and Xebangfai bridge road no 13 station should be continuously observed in order to get good results in simulating flood flow in river networks The resolution of digital elevation map (DEM) should be smaller, such as 30x30 meter The relevant agencies and planners can use these maps complement and improve their land use planning and practices and consider the vulnerability of areas such as resident, industrial area These maps provide the information that can lead to reduce the impact of flooding It should be emphasize on the improvement of the perception and warning system of local communities and authorities regarding to flood process and its hazardous effect 78 da da i ho da i ho c da i ho c th da i ho c th uy da i ho c th uy loi da i ho c th uy loi
