| Abstract | At present there is no master plan for flood management in Thailand. There are many plans, which have been developed by many organizations. There is no standard policy and procedures established to effectively manage floods in comprehensive and efficient way. There are intensive activities involved in floods but there is no sequence of activities and responsible organizations to deal in floods. There is no mechanism for law enforcement. At present, flood management in Thailand is done by many organizations according to their own purpose with lack of integration or comprehensive planning and co-ordination. There are 9 ministries, 20 departments, non-government organizations and communities involving in flood management There is no single agency that is fully responsible to overall flood management. Even more, there is no legislation support for organizations to co-ordinate and manage flood control, mitigation and recovery. There is insufficient flood control structure and also other flood control measures. Insufficient of on-line monitoring system for rainfall and flood level is also the main problem to follow the flooding situation. There is an essential need to establish a national flood forecasting and warning system. Reactive approach in disaster management was practiced in Thailand in the past. Proactive approach is recommended in this study by using combination of engineering, education, enforcement and disaster preparedness, readiness, response and recovery. Master plan for flood management in Thailand can be classified into national, river basin and sub-basin level. Each level consists of four steps of flood management. Each step of flood management can be divided into people section and government and non-government organizations section. Structural and non-structural measure will be used in flood management programs. The important mechanism that force flood management program to be effective is institutional arrangement. This study proposed three alternatives of institutional arrangement and the best alternative is Alternative C. The Utaphao river basin in Songklha province in the south of Thailand is selected to be a pilot project for this study. Hat Yai city which was heavily flooded situates in Utaphao river basin. Flooding in 2000 was the largest flood in Utaphao river basin and caused enormous damage. The causes of flood are due to heavy rainfall, insufficient drainage and improper land use. There are many flood control measures in the Utaphao river basin: Three alternatives of flood control measures for the Utaphao river basin are proposed. Alternative I consists of a shortcut channel. Alternative II consists of two diversion channels. Alternative III is the combination of alternative I and alternative II. The effect of flood control measure was evaluated by MIKE11 model simulation. Flood control measures can reduce flood water level at station X-44 by-0.79 m, -2.57 m and - 3.13 m respectively according to Alternative I, Alternative II and Alternative III. There is very little effect by these structural measures on water levels for station X-90 located upstream of the proposed flood control measures. |
