On the Course of Flowing of Fluvial Water Poured into Simoda Bay, Izu

Abstract

The writer has investigated the diffusing process of the fluvial mater which is poured to the heart of Simoda Bay. The fluvial water advances and is shifted to the comparatively separatel area on account of wind direction in situ, in stead of spreading all over the bay surface. But when wind velocity is weaker, the brackish water zone is localized to the west part of the bay against wind owing to the counter-clockwise current which is proper in this bay. The writer has recognized an apparent relationship between deficient salinity at the river mouth and flowing distance of the fluviatile water which is emitted far in the offing.
