IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

ABSTRACT
The present study aims to clarify the thermal function of tidal flat and mangrove areas in the summer and winter. We
conducted long-term field measurements for water and soil temperatures in Sumiyo Bay, Amami Oshima Is., known as a
habitat of the fish species Ryukyu-ayu. The results showed that the water temperature of tidal flat and mangrove areas
was close to that of the outer sea in the summer and the rivers in the winter, showing the heat fluxes from the water
surface and the bottom were dominant in tidal flat and mangrove areas. A heat budget analysis indicated that the sensible
heat flux from the bottom of the tidal flat and mangrove areas significantly cooled water column in the winter.
