Open Campus in 2022
Open Campus was held on July 17, 2022. Many people visited the Hydraulics, Coastal and Environmental Engineering Laboratory again this year.
We went to the field survey of Asja River.
The field survey was conducted from the upstream end of the Aja River to Sueyoshi Park in the middle part of the river.
We tried the latest craze.
We went to the field survey of the flood that occurred in the Kohatsu River on May 31st.
On May 31st, 2022, a heavy rainfall occured in the Okinawa main island. According to the Japan Meteorological Agency, the precipitation was recorded at around 110 mm per hour in Nanjo City, which led to the occurrence of flooding mainly in the southern part of the Okinawa main island. Since there was information on flooding around the Kohatsu River, which is an objective rvier of our research, we went to the Kohatsu River for a field survey.

Tree planting to commemorate the solution of the "Shimoji paradox" regarding the overtopping flow coefficient
The research on the wave-overtopping flow coefficient that we are tackling with is the research that former Ryukyu University professor Tsugio Kono (He died at the age of 65) started when he was an assistant at Tokyo Institute of Technology. The concept of "weir formula (discharge coefficient)", which has been dealt with in river engineering field, is applied to the predection of the wave-overtopping flow rate....
Prof. Eizo Nakaza's presentation about “Tsunami Stones” was published in newspaper Miyako Shinpo.
Tsunami stones scattered along the coast in Miyako Jima island are one of the most beautiful scenery in the world. At the initiative of Prof. Nakaza, efforts to register this tsunami stone group as a World Heritage site have started. To commemorate the start of the initiative, Prof. Nakaza made a presentation at the Miyako Jima Future Creation Community Center on July 28, stating that "the tsunami stones in Miyako Jima island were carried only by the Great “Meiwa” tsunami that occurred in 1771". The efforts to register the tsunami stones as a World Heritage site and Prof. Nakaza’s presentation were published in newspaper Miyako Shinpo.
