As the President of Iranian Committee on Large Dams (IRCOLD), I am so delighted to welcome all participants of the 4th International Conference on Long-Term Behavior and Environmentally Friendly Rehabilitation Technologies of Dams (LTBD 2017) on October 17-19, to Tehran, Iran.  This is an excellent opportunity for Iran to be the host of this international scientific event and we are happy to have distinguished scientists, engineers and other professionals involved in the dam industry here in Tehran.

Conference will start with pre-study tours and technical sessions and will be followed by workshops and post-study tours.  The workshops will provide an international forum for the academics from universities and institutes and practicing engineers from private and public firms to present and discuss their up-to-date reviews of recent accomplishments and the future trends in the field of dam engineering.

I believe that LTBD 2017 conference will have an impact on the development of dam engineering, and will also provide a forum for discussion, sharing knowledge and experiences, innovative ideas, research results and will foster collaboration amongst the participants.

Away from the technical program of the conference, we hope you will enjoy the social and cultural events in Tehran: the Opening Ceremony, Welcome Reception and City Tours.

I hope you accept my sincere invitation and contribute in establishing an informative, successful and productive conference and help us to achieve our goals. I am extremely sure that your kind contribution will promote and enhance the level of the conference.

I look forward to see you in Tehran for LTBD 2017 and hope that you enjoy the Iranian hospitality during your stay.
