Using a survey questionnaire, the reasons for flooding and perceived remedial measures were gathered from the barangay residents. The existing lengths of the drainage canal in the barangays range from 0.52 – 2.263 km. The average slope of the drainage canal in the barangays ranges from 0.012 – 1.572 %. The average depth of maximum flooding ranges 0 (no flooding) – 1.3 m. The computed drainage density for the different barangays ranges 2.92 – 32.46 km/km 2 while the computed additional lengths of drainage needed in the barangays ranges 0 (sufficient length of existing drainage canal) – 4,954 m. On the other hand, the most common reasons for flooding are small drainage canals, clogged drainage canals, no drainage canal, water coming from other puroks, and flooding from Catarman River or a nearby creek. The most common remedial measures perceived by the barangay residents are construct a drainage canal, drainage canal maintenance, construct river control, and repair of the existing drainage canal. The researchers concluded that the barangays with high drainage density has no Original Research Article
