Abstract
A field observation was performed to know the transports of particulate materials in a mangrove area. In the observation, the concentrations of dissolved and particulate materials and the temporal and spatial variations of soil environment in the mangrove forest were measured. A numerical computation for the transport of suspended sediments and the associated transport of nutrients during flood was performed for two different types of flood. The results of the observation and the computation have revealed that the movement of particulate materials in the mangrove area is much influenced by the phase-lag between the peak of flood and the tide. It was also found that phosphorous is provided to the mangrove forest by floods.
