内容記述タイプ Abstract
内容記述 On the Abashiri River in Eastern Hokkaido, the inflow and accumulation of natural and artificial pollutants
has increased the risk of blue tides, which can damage fishery. This study examined the use of
a permeable fishing weir, similar to those used for catching salmon, in controlling salinity intrusion. Hydraulic
experiments and numerical calculations revealed the following. 1) Conventional one-dimensional
two-layer flow models that consider form drag at the boundary between fresh and saline water can reproduce
the behavior of the saline wedge. 2) Permeable structures, such as fishing weirs, are effective in
controlling salinity intrusion when the tide is changing from neap tide to spring tide, but not when it is
changing from spring tide to neap tide. However, numerical calculations suggest that halfway between
spring tide and neap tide, the seaward flow of fresh water is reduced by the permeable structure, which
allows saline water in the river channel to intrude upstream into the lake.
