Recently in some cities of cold-region land use has been advanced in theareas which have the worse physical conditions, for instance, low lying area, weak and soft-donditional land and peaty foundation land. In such cities the efforts to increase the stability of land use against flood hazards are vital, then in the respect two modeling methods were proposed : one is the simulation model using the backward integration technique of System Dynamics in order to represent historical regional activities between land enhancement and flood control measures. The other is the multiobjective optimization model in order to estimate the future potential of housing development area in consideration of regional flood condition. The result of two modeling methods shows that both methods shows that both methods were available to identify the complicated relationship between the land use activities and flood control measures. Especially, the adequacy of backward integration technique of System Dynamics was confirmed in order to reproduce the long-term historical facts using cause-effect relationship. The optimization in terms of the Surrogate Worth Trade-off method gives the scale of land enhancement by means of evaluating two objectives, the maximization of regional service from land use and the minimization of the public flood control cost.
