IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

ABSTRACT

A concept o of the “regions s of freshwateer influence ((ROFIs)” was s proposed by y Simpson (1 1997). Genera ally, ROFIs ar re
considered a as one of key f factors to dete ermine conditio ons of marine environment and ecosystemm in coastal a areas. Thus, w we
focus on fres shwater dynam mics in the gu ulf type ROFI oof the Ariake Sea, Japan. TTo understandd salinity strattification due tto
freshwater in nput from mu ultiple rivers tthrough flood d events, in-ssitu measurem ment for 25ho ours on tidal current, CTD D,
turbulence m micro-structure e, and suspendded solid (SS S) grain size p roperty was c conducted at a a single point in the norther rn
Ariake Sea, Japan, in Ju uly, 2014. Fro om the result ts of the meaasurement, th he followings were clarifie d: 1) Sub-tidaal
development t and decay p process of saliine-freshwaterr stratification during flood season was m measured. Th he time scale oof
stratification was able to c change with a a dimension o of flood; 2) De ependence of tempo-spatialal distribution oof chlorophyll--a
(phytoplankto on) on the diff erent mechan nism from stratatification due tto freshwater transport and d mixing in the e bay was seenn;
and 3) Relati ionship betweeen DO and de evelopment of stratification wwas exhibited..
