The analysis of drainage paths in Chao Phraya river basin by graph theory

Flood is one of the natural hazards and it is critical to be controlled through proper management. Severe flood events in Thailand (2011) caused damage to both life and property. Moreover, heavy flood or drought affected life, existence and the country´s economy. Therefore flood control is important. This study proposes methodology for analyzing drainage paths in Chao Phraya river basin by graph theory and simulation connection between floodgate and water gauging stations to find out capability of stations. After that capability and efficiency of station were compared to determine which stations can receive water more than maximum performance and to find out solutions for stations.
