Alvarado cited the problem of flooding in Bulacan and the solution promised by the creation of mini dams in Nueva Ecija and Candaba swamp to prevent backflooding
through the coastal areas.
About 20 barangays in Calumpit and four in Hagonoy were experiencing 'backflooding
,' said Liz Mungcal, head of the Provincial Disaster Risk Reduction Management Office (PDRRMO).
The waters enter through sinkholes and other geological features, as well as backflooding
of the Green River.
