Abstract

An intensive field survey was carried out in Inohana and Hamana Lakes including a narrow channel to investigate the characteristics of flow and material transport between the two lakes. In the vertical profiles of flow and phosphorus concentration, Inohana Lake has a two-layer structure under stratified conditions; the outward flow and particulate phosphors (PP) in the surface, while the inward flow and dissolved phosphorus (DP) in the middle and bottom. The surface discharge in the channel can be estimated from the wind. Using a simple box model that made use of salinity as a tracer, the horizontal and vertical exchange of waters were calculated and agreed with the observed ones. The vertical transport of salinity was influenced by advection and responded to the density field, i.e. the degree of stratification.
