[MIS06-04] Nutrient uptake in river networks controls nitrogen and phosphorus transports along the river-to-ocean continuum
We will present our recent empirical studies in the Fuji River watershed, which show the“basin metabolism”of nitrogen and phosphorus to identify the fate of river-borne material along the land-to-river-to-ocean continuum. Moreover, our study will show the relationship between fluvial geomorphology (e.g., channel size and river network structure) and the riverine transport of nitrogen and phosphorus. We emphasize that physical modifications of river network strucutre may affect the delivery of nutrients to coastal areas, resulting in change of the strength of land-ocean linkages through riverine nutrient flux.
