Abstract/Summary
Abstract. The study analyzes the effects of the existing Manggahan Floodway and the Napindan Hydraulic Control Structure in the occurrences of recurrent flooding in Barangay Napindan.
The study makes use of the flow-depth rating curves of river segments, existing bank profiles, and water profiles in order to obtain critical depths at different discharges of different return periods.
Results show that at a flow of 1,350 m 3/sec (2-year return period) the critical stage in the lake would be 11.0 m. For a 5-year return period, the flow of 1,800 m 3/sec, the critical stage in the lake would be 12.0 m. This indicates that while Manggahan Floodway can accommodate 2,400 m 3/sec, lesser amount of flows would already inundate portions of Taguig at lesser return periods.
The different flood alleviation schemes are evacuation of residents of Barangay Napindan to two-storey buildings during intense rainfall, flood escape routes, flood warning, widening of Napindan Channel and Pasig River.
