内容記述タイプ Abstract
内容記述 The ecosystem in the tidal region of a river tends to be diverse because of seawater intrusion. Such an
ecosystem is observed in the Abashiri River in eastern Hokkaido. The downstream end of Lake Abashiri
is about 7 kilometers from the Abashiri river mouth. The lower layer of the lake is saline water that has
flowed upstream from the sea. Dissolved nutrient salts from the saline water layer make the lake a good
fishing ground. However, in recent years, the damage to fishery of blue tide happens frequently because the
fresh water depth of the lake became shallow. One solution is based on the comb-shaped weir traps that are
used for catching fish in Abashiri River. Mesh structures that simulate weir traps were used in laboratory
experiments to study the relationship between mesh porosity and salinity intrusion velocity. The following
findings were obtained: The salinity intrusion experiment showed that when the mesh porosity is low, the
flow velocity decreases before the water reaches the structure, and that the flow velocity does not differ
greatly between before and after passing through the structure.
