●Boussinesq equation
This theory is used for calculation ofwave deformation in shallow waters
at ports and coasts. The waves
around coastal structures can be
estimated accurately because thistheory takes into account wave
refraction and diffraction as well as
long-period waves induced by
nonlinear wave interaction.

●Yorimawari waves or long-period
waves traveling to Toyama Bay
This is a swell which is generated by storm
wind in the northern area of the Japan Sea andtravels long distance to Toyama Bay. It haslong been known as "Yorimawari waves" since
it hits various villages of Toyama Bay, circulating inside once it comes.

.NOWPHAS (Nationwide Ocean Wave information network for Ports and HArborS) is the ocean
wave information network of the Japanese coasts
that Ministry of Land, Infrastructure, Transport
and Tourism has maintained. This information isused for wave forecast by the Japan Meteorological Agency (JMA) and contributes to navigation
safety.

Wave observation data (height,
period, direction) obtained atmore than 50 observation stationsof NOWPHAS have been stocked
at COMEINS since 1991.Clients canaccess and view them in the formof time charts and tables.

Social infrastructure, which was mostly developed during the period of Japanʼs rapid economic growth, now requires massive renewal. It is crucial
for coastal structures to be properly maintained, managed and preserved because they are placed in a severe environment such as salty waterand consolidation settlement of soft ground. CDIT addresses these technological challenges and conducts necessary research .

Worldwide dissemination of knowledge on disaster mitigation measuresagainst tsunami
CDIT edited a book titled “TSUNAMI---To survive from tsunami” and published its Japanese version from Maruzen Publishing Co. in November 2008 to help people
survive a tsunami. Then, CDIT successively published a book “TSUNAMI” in English and Indonesian languages, respectively from World Scientiﬁc Publishing Co.
and PT. Sarana Komunikasi Utama. In addition, CDIT held workshops in Indonesia and other disaster stricken countries by Indian Ocean Tsunami to disseminate
knowledge on tsunami and necessary precautionary measures to mitigate disasters based on the book “TSUNAMI”. This project was ﬁnancially assisted by a Nippon
Foundation. In connection with English and Indonesian publications, CDIT is commended and awarded "the Book of the Year 2009" by Japan Society of Civil Engineers.
Thereafter, CDIT edited a book titled "Tsunami is Deadly." which is a much easier version for children to understand major points written in the book "TSUNAMI",
and published it in various languages such as Japanese, Indonesian and Spanish.

Maritime and port & harbor facilities in Japan were mostly constructed about half a century ago during a rapid economic growth, andtherefore faces growing challenges for aging and proper maintenance. Accordingly, CDIT examines and certiﬁes “Maintenance Engineer
for Port and Harbor Infrastructure” as a qualiﬁed engineer who is expected to play a leading role in preparing a maritime and port andharbor facility maintenance plan and its implementation.
