[II-18] Examination of trend grasp of electric conductivity for rivers in 47 prefectures nationwide
Keywords:Water quality indicator, Electrical conductivity, Open data, National survey, GIS (Geographic Information System), Database
Electrical conductivity (EC) as a water quality indicator is used to study the material balance and water balance in basins and rivers, and to investigate the effects of tidal water. Also, the measurement is easy and low cost, and the convenience is high. However, absolute evaluation of measured values is difficult, and it has not spread to schools and civil activity levels. Therefore, relative evaluation of measured values can be facilitated by preparing a database of EC nationwide. In this study, with the national survey in mind, it was first designed to outline the existence of open data and its tendency, with the Chubu and Kanto regions as models.
