 Major Recent Technological Assistance Cases

The Japan Dam Engineering Center helps dam builders to solve technological problems related to their work at every stage of a dam project - surveying, design, construction, and management - by providing high-level and comprehensive technological assistance in response to requests from national or prefectural governments. To provide this assistance, the JDEC uses the comprehensive results of its survey and research work.
