Experimental Fields for River basins in Cyberspace We are gradually accelerating the use of "Digital Testbeds for River Basin-wide Integrated Water Management"!

The Ministry of Land, Infrastructure,  Transport and Tourism (MLIT) in Japan has been promoting the development of "Digital  Testbeds for River Basin-wide Integrated Water Management*"(DTB), experimental  fields for river basins in cyberspace. The DTB enables technological  development and demonstration experiments to be conducted in a cloud  environment by utilizing various data related to river basins, and is expected  to accelerate research and development and on-site implementation through  industry-academia-government collaboration.

Now that it is possible to provide rainfall  and topographical data, analysis environment, and visualization tools, etc., we  will begin trial use in October 2025, in order to improve convenience from the  viewpoint of early realization of effects, identification of issues and  solutions for use, and improvement of usability. The National Institute for  Land and Infrastructure Management (NILIM) will start with research and  development of river management methods using satellite data.

The experimental use will be expanded in  stages through research and development at the NILIM and trial use by adopters for  the MLIT Grant Program for Research and Development on River Improvement  Technology, which began in October 2025.

[Outline of the DTB]

■Purpose and  functional overview

Please refer to the Appendix and the website  below for details on the purpose and functional overview.

■Overview of  trial use after October 2025

Research and development will be conducted on  the DTB, utilizing satellite data and topographical data, to develop a method  for longitudinal monitoring of river water levels and a method for monitoring  the deformation of facilities such as dams. (Attachment:  https://www.atpress.ne.jp/releases/549030/att_549030_1.pdf )

In addition, adopters who wish to use the DTB  on a trial basis may do so for some of the projects in the " the MLIT  Grant Program for Research and Development on River Improvement Technology in FY2026"  that began accepting applications on October 10, 2025.

*The name of the DTB will be changed from  "Digital Testbeds for River Basin Disaster Resilience and Sustainability  by All", which has been used in the development stage, to "Digital  Testbeds for River Basin-wide Integrated Water Management" with a view to  developing measures for River Basin-wide Integrated Water Management.
