The environmental assessment of around groundwater is need in the case of dewatering method. In the constructing Rakunan clean-up center of Kizu river, the dewatering method will be applied for the confined groundwater. The usable wells exit around this construction therefore the evaluation of the influence for these wells will be needed. We have made the three dimensional layer’s model referring the sixty five boring logs what Kansai Geo-informatics publishes in this area. And we have simulated the three dimensional seepage flow using this model. It was found that the influence of this dewatering method is very little serious.
