| Research Abstract |
In order to clarify the mechanisms for creation and maintenance of biodiversity in the floodplain of the Tagliamento River, we conducted a series of field works on measurement of the sediment production in the basin and monitoring surveys on the geomorphological changes in the floodplain using interval cameras. Faunal biodiversity of each habitat type within the flood plain was investigated based on DNA sequence data of the community level, and at the same time, parameters of community metabolism such as organic mater origin and respiration rate were also measured for each habitat type. Methods for prediction of changes in these ecological functions under changing sediment and flow regimes have been developed using 2D flow and sediment transport model in the braided river channels.
