INVESTIGATION OF WATER EXCHANGE THROUGH RIVERBEDS IN TIDAL RIVERS

摘要：

The longitudinal profile of salinity near the riverbed and the measuring method of water exchange through the riverbed in a tidal river were investigated. Observation of the Ota River Floodway showed that high salinity water masses occurred sporadically on the riverbed from the middle to the upstream reaches. The groundwater discharge through the riverbed was successfully estimated and was verified by the observed salinity of groundwater below the riverbed. The calculations provided evidence that water exchanges through the riverbed ranged from 10-3 cm/s.Water exchange was significant at the 30 cm below the riverbed surface.
