The research results of this research are as follows :1)The state of a hydrological cycle and utilization of groundwater in low land city Osaka was examined, and it is pointed out that the elucidation of the groundwater cultivation mechanism for the whole Osaka basin is indispensable to develop the groundwater management system that enables new utilization of groundwater.2)In order to develop the groundwater simulation model of the Osaka plain, it is necessary to prepare the 3-dimensional geological structure model of the Quaternary layers. The plans (stripping off topographical maps) showing the distribution depth of typical layers from the information on the Quaternary layers around the Osaka plain were made, and the 3-dimensional geological structure model was built based on it.3)The data format of groundwater information was unified, and the database on the Osaka plain was built to link to GIS (Geographic Information System).4)From the analysis based on the statistical simple model, the influence relations between rain/tide-level/pumping and groundwater level were clarified in the Osaka city region, and from the analysis of dissolved components of the groundwater in the shallow aquifers, the cultivation flow paths in the Osaka basin were clarified. They are used as the basic data for the comprehensive management of groundwater.5)In order to establish sustainable groundwater utilization system, holding the wholesome hydrological cycle, a comprehensive management of groundwater is an indispensable system. The groundwater cultivation model for the regional groundwater management in the Osaka plain (broader-based groundwater flow analysis system) was developed, and the applicability to the comprehensive groundwater management of the proposed model is clarified using the accumulated information.

这项研究的研究结果如下：1）检查了低陆城市大阪的水文周期和地下水的利用状态，并指出，整个大阪盆地的地下水培养机制的阐明是必不可少的，可以开发出必不可少的地下水，以开发出依赖地下水的新地下水。2）准备第四纪层的三维地质结构模型。制定了从大阪平原周围的第四纪层的信息中的信息中的典型层的分布深度（剥离地形图），并制定了三维地质结构模型，基于IT构建了3维地质结构模型。在大阪市区阐明了雨/潮汐水平/抽水和地下水位，并通过分析浅水含水层中地下水的溶解成分，大阪盆地的耕种流道澄清了。它们被用作地下水全面管理的基本数据。5）为了建立可持续的地下水利用系统，保持有益健康的水文周期，地下水的全面管理是必不可少的系统。开发了大阪平原区域地下水管理的地下水培养模型（基于更广泛的地下水流量分析系统），并使用累积信息阐明了对拟议模型的全面地下水管理的适用性。
