Students from Kerala, India visited our university and did an internship on the hydrodynamics of estuaries.

Three excellent third-year undergraduate students from TKM College of Engineering, Kollam, Kerala, India visited Tokyo Metropolitan University (TMU) in May 2023, and they underwent 3 weeks internship on hydrodynamic studies on estuaries at the Department of Civil and Environmental Engineering from May 9 to June 1, 2023. Although we have been conducting online internships for TKM students for the last three years, this was the first time the students from TKM visited TMU for an internship. The major activities of the 3 students during their stay at TMU has given below:

◆ They learned to operate different types of equipment such as conductivity temperature depth (CTD) probe with an optical backscatter sensor (AAQ Rinko, JFE Advantech, Japan), YSI ProDSS multiparameter digital water quality meter (Xylem, Japan), HOBO U20 water level logger (Onset, USA), light microscope (NIKON: ECLIPSE series, Ei, Japan), etc. to collect and analyze data.

◆ They visited a salt marsh (newly formed after the Great East Japan Earthquake), Moune River, and Kesennuma Bay in Kesennuma, Japan for 3 days. During the 3-day field survey, they conducted (i) the measurement of the vertical profile of salinity and turbidity at different locations (39 stations) of salt marsh, river, and bay, (ii) dissolved oxygen (DO) experiment in the salt marsh, (iii) water sampling for plankton analysis in the bay, and (iv) maintenance of salinity and water level sensors.

◆ They visited the entire TMU campus in Minami Osawa along with other members of the laboratory and understood the facilities in a Japanese university. They also visited many places in Tokyo such as Asakusa, Akihabara, Shinjuku, Yokohama, etc. and explored the vibrant and rich culture of Japan.

◆ They analyzed the vertical and longitudinal distribution of salinity and suspended sediment concentration in the Ashtamudi estuary, India during a neap-spring tidal cycle and compared it with the characteristics of the Chikugo River estuary, Japan. They presented their research findings and other experiences during their 3-week stay to the students and faculties of hydraulics and coastal laboratories on the last day of their internship.

The students (both Japanese and international) of the hydraulics laboratory supported the TKM students during their stay at TMU and they had very fruitful interactions and discussions about their individual research, cultural differences, and the education system in India and Japan. We will continue to hold this kind of collaborative exchange program in the future.
