Abstract

In the Kotaki River Valley, Japan, sediment-related disasters occur over extensive areas from headwater to downstream cities and in a variety of forms. On the Kotaki River, the potentially large quantity of sediment discharge during floods was reduced by installing 3 sets of slit barriers to prevent landslides while allowing the passage of fish. This dam system was modelled after extant slit barriers of this nature. Previous investigations of temporal changes in sediment-regulating function and sediment outflow in river sections with continuous slit barriers have incorporated many unknown factors. The AA. performed a numerical simulation of a section of the Kotaki River containing slit barriers to prevent landslides and examined here the characteristics affecting sediment-regulating functions
