We will start "understanding and analyzing the amount of sediment deposition in rivers, etc." utilizing digital technology!

　The rivers managed by Yokohama City are about 86 km, and visual inspections (analog) are carried out on foot. However, due to the enormous amount of labor and the skills and experience of the staff, there is a difference in the inspection results.
　In order to solve this problem, we conducted two demonstration experiments with different approaches from April to August 2023, using the digital evolution and co-creation platform "YOKOHAMA Hack!", We conducted two demonstration experiments with different approaches from April to August 2023.
　Based on the results of the demonstration, we have made a consignment order using the comprehensive evaluation bidding method, and we have concluded a contract with Pasco Co., Ltd. for "understanding and analyzing the amount of sediment deposition in rivers, etc."
　In the future, we will utilize digital technologies such as AI image interpretation of aerial photographs and measurement using satellite positioning systems (GNSS survey), ascertain the location and amount of sediment deposited in Yokohama City-managed rivers, leading to effective maintenance. We will further improve flood control safety.
