Abstract: Two mathematical models for routing floods in rivers and flood plains namely the SSARR and DFR models have been selected and applied successfully to the Chi-Mun river basin, Northeast Thailand. For this present study, the major points of interest are: l) the ways in selecting the mathematical models based on the complexity of the river and flood plain network, the unavailability of the cross sectional geometry and the significance of backwater effects; 2) the method used in computing flood flow in rivers and flood plain network and the calculation of overbank flow exchange between them; 3) the procedure in calibrating the models during the overbank flow period in which the flow exchange between the rivers and flood plains is signif icant. There are not so many studies that deal with flood plain modeling. The present work is therefore a good example for other investigators who are intending to solve similar problems.
