Multi-Lingual Technical Dictionary

The Multilingual Technical Dictionary (MTD) of all technical terms related to irrigation, drainage, flood management, environment, river training and allied disciplines (see contents below) is a flagship publication of the ICID. First published in English and French languages in 1967, the – 4th  edition of the MTD (English-French) was brought out on CD-ROM in the year 2002. Current – 5th  edition defines 9370 technical terms in Chinese, Japanese and Russian, besides English and French.

The MTD brings coherence in sharing and exchange of experiences and has proved to be highly useful for engineers, researchers, students, professionals, planners, designers, academics and all others related with the field of irrigation and drainage. Any term/ definition can be printed/copied with the option to download/updates of terms from the ICID website.

The online version of the Multilingual Technical Dictionary (MTD) is based on the 5th edition released in 2009 in DVD format. This version includes 9370 technical terms with matching English and French translation. The DVD version also includes terms collected in Chinese, Japanese and Russian languages with the active support received from respective National Committees. However, full integration with online version has not taken place due to difference in available translation editions/ versions.National Committees of Iran, China, Japan, Russia, Korea, and India are working on the translation/  updating part to match the present online version.
