项目摘要

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.

本研究的研究成果如下：1)对低地城市大阪的水文循环和地下水利用状况进行了考察，指出阐明整个大阪盆地的地下水培育机制是必不可少的。开发地下水管理系统，实现地下水的新利用。2)为了开发大阪平原的地下水模拟模型，需要准备第四纪地层的三维地质结构模型。根据大阪平原周边第四系地层信息，绘制了典型地层分布深度的平面图（剥离地形图），并在此基础上建立了三维地质结构模型。3）地下水数据格式统一信息，建立大阪平原数据库，与GIS（地理信息系统）连接。4）根据统计简单模型分析，得出降雨/潮位/抽水与地下水位的影响关系澄清了大阪市地区的情况，并通过对浅层含水层地下水溶解成分的分析，明确了大阪盆地的栽培流路。作为地下水综合治理的基础数据。5)为了建立地下水可持续利用体系,保持良好的水文循环,地下水综合治理是不可缺少的系统。开发了大阪平原区域地下水管理的地下水培育模型（更广泛的地下水流分析系统），并利用积累的信息阐明了该模型对地下水综合管理的适用性。
