Water resources study for Strategic flood risk management in Chao Phraya river basin

Abstract

The research is to develop the mathematical model to study the flood at the basin of Chao Phraya River. At the C.2 station from Jiraprawat camp, Muang District, Nakhon Sawan Province to the mouth of river in Phra Samut Chedi District, Samut Prakan Province The purposes of this research are to study the water resources for Strategic flood risk management in Chao Phraya river basin by using the iRIC (Nays2DFlood) model and database with Digital Elevation Model from NASA Earth Science data to develop the flood model at Chao Phraya River with 30*30 specification in UTM system referring to WGS1984 UTM Zone 47N and using the data rate of water flow from the big flood between 31 August, 2011 to 30 October, 2011 to put in the model for study the water flow characteristics in the watershed and evaluate as well as predicting areas that will be affected by floods under the amount of water in the Chao Phraya River at the C.2 station use Nays2DFlood model to produce the flood map and flood risk map. The map is include  flood depth and the flood area. It is for the prevention and the relief from flood in the future.
