Abstract

The Pampanga and Angat River Delta, located on the northern side of the Manila Bay in a large alluvial plain, are regularly confronted with worsening fluvial and tidal floods. Subsidence rates up to 4.5 cm/year due to excessive groundwater extraction are the main cause of the worsening floods. Five measures are presented to reduce the floods: - Groundwater Extraction Regulation, - Levee Maintenance, - Improve Dam Operation with precipitation forecasts, - Fishpond Dike Height Regulation with a fishpond flood channel as first phase, - A ring levee consisting of smart road elevations and tidal gates. A 3Di model is used to estimate the future scenario and the assess the potential measures. The Fishpond Dike Height Regulation is identified as the most effective measure.
