A modeling system is constructed by integrating an one-dimensional unsteady flow simulation model and a hydrologic model tosimulate flood flows in drainage channel networks of paddy-field districts. The modeling system's applicability is validated by simulatingflood discharges from a paddy-field district, which consists of nine paddy fields and one drainage channel. The simulation results arein good agreement with the observed. Particularly, in the verification stage, the relative errors of peak flows and peak depths betweenthe observed and simulated hydrographs range 18.58 to 39.01 % and －10.26 to 2.97 %, respectively. The modeling system's capabilityis compared with that of a water balance equation-based model; it is revealed that the modeling system's accuracy is superior to theother model. In addition, the simulations of flood discharges from large-sized paddy fields through drainage channels show that the flooddischarge patterns are affected by drainage outlet management for paddy fields and physical characteristics of the drainage channels.
Finally, it is concluded that to efficiently design drainage channel networks, it is necessary to analyze the results from simulating flooddischarges of the drainage channel networks according to their physical characteristics and connectivities.
