A flood is not a sudden disaster, so we can predict and prepare for a flood beforehand. We paid attention to this thing and had developed a prediction numerical model of the flooding area that high-speed calculation is possible. In this paper, we developed the support system which evaluating an effect of levee protection activity quantitatively and deciding of scale of levee protection activity. This system is built in a geographical information system to manage topographic map and spatial information, and the prediction numerical model. We did simulation the effect of levee protection activity by using this system. So, we suggested technique to estimate reduction rate of the quantity of flooding water and area by levee protection activity, and evaluate a quantity of possible work till flood arrived at it.
