An Intensive Field Survey of Physical Environments in a Mangrove Forest

摘要

A field observation of physical environments in a mangrove forestwas made in Fukido River with a surrounding mangrove swamp inIshigaki Island, Okinawa, Japan. The characteristic flow structures areobserved in creek and swamp and then found to be similar tohydraulic phenomenon in a compound meandering channel. Thethermal environments in the creek and swamp are investigated by aheat budget analysis, indicating the significant importance of the heattransport by tidal current and the heat flux to swamp bottom. We alsoexamine the sediment dynamics in detail by measuring a verticalturbulent flux of suspended sediments.
