If the drainage systems and canals are filled with trash, any great amount of rain will immediately cause flooding and bring more destruction when a catastrophe hits. This is exactly the canal flood risk that Midsayap, North Cotabato should have considered.
Clogged canals are one of the reasons why numerous areas become flood-prone. This is evident in the experience of Midsayap City, North Cotabato, Philippines on August 4, 2020. Within an hour of downpours, a surge of water occurred and the clogged canals contributed to it. The residents of Midsayap might not have realized the canal flood risk since it was a sudden event.
Nevertheless, YES, we should take into account the risk of canal flooding if we do not want to witness the heavy price that comes with it. But, before we tackle the risk, let us first know the types of canals.
Two weather systems are currently affecting the conditions in different areas across the Philippines. The Northeast Monsoon or Amihan is causing cold winds over the extreme northern Luzon; and the Easterlies or the humid air coming from the Pacific Ocean on the eastern portion of the country.
