Case story

Flood Mitigation, Almacen River

Philippines, Bataan

Flooding was inevitable during the rainy season due to the severe siltation of deposits in  Almacen river. Geotube® was used as a silt depo at the river mount and the 4.0 km river of lahar deposits was dredged to help deepen the river channel to accommodate a more significant volume of water.

The dredged material along the river was used as filling soil for the river embankment and slope protection that was part of the river improvement project. With the dredging project and improvement of waterways leading to the Almacen River, flood waters were diverted away from the surrounding villages.
