Protecting Lives from Disasters

Works to countermeasure disasters

Measures at Osawa Alluvial Fan Area

①Measures by the valleys

These measures prevent riverside erosion due to debris flows.

②Iwadoi Observation Posts

These posts take images of debris flows and collect data necessary for debris flow analysis, such as flow rates and water level.

③Groundsills

Groundsills allow for safe deposition of debris, thus preventing the movement of sediment downstream.

④Sediment-control Forest Zone

Sabo forests by the riverbed will be properly managed in order to improve the function of the sand basins.

⑤Excavated sediment trap works

These trap works are there to keep the fine particles from flowing downstream.

⑥Stockyards

These stockyards temporarily trap the sediments deposited after a debris flow, which can then be used as a block production yard.

⑦Forest Zone Reinforcement Work

Steel slits are installed to prevent boulders mixed in debris flow from hitting the sabo forests directly.

⑧Training Levee

These levees prevent debris flows from entering fields, houses, forests, etc.

⑨ River Channel Works

This sturdy flow channel with 3 concrete surfaces prevents the erosion of riverbeds and riverbanks due to floods, let the water flow downstream without much difficulty.
