PROPOSAL FOR DX IN URBAN RIVER MANAGEMENT USING DIGITAL TWIN

Abstract

Many urban rivers are lined with concrete revetments constructed in the 1960s and 1970s, and as they deteriorate over time, the importance of river inspections is increasing. However, due to the increase in the number of defective sections and the shortage of skilled engineer, various problems have become apparent. In this study, using Yokohama City as an example, we extracted the current issues of river inspection in local governments and proposed the River Management DX that contributes to solving these issues. The proposed DX consists of a workflow that combines AI and human inspection, and an application to realize the workflow, based on the premise of digital twin. This paper describes the findings of a trial run of the proposed river management DX on a section of a river in Yokohama City and its future prospects.
