When a typhoon visit Philippines last month I was there, our province was in signal # 2. The wind was very strong and after few hours heavy rain came. There was no problem if there’s no flood, yeah right the water from the field went out the street and came to our houses. The main reason was the street canal made by someone who said to be an engineer was too small to accommodate the water so guess what the water overflows from the canal.
Same problem with the irrigation canal beside us, it was also too small that when there’s large amount of water when they opened the dike it was flooding in our place. Dunno what are they thinking when they made it, because it looks like just a toy or house canal.
