Short summary
Using multi-geochemical indicators, this study revealed that the contribution of river water and groundwater as water sources differs among the backwaters in the floodplains of an urban river in Tokyo, influencing the internal balance of nutrients (nitrate, phosphate, silicate). Consequently, the presence of backwaters in urban rivers is expected to provide diverse aquatic environments, suggesting a potential contribution to maintaining biodiversity in the floodplain.
Using multi-geochemical indicators, this study revealed that the contribution of river water and...
