The investigation presented in this report provides a hydrology and hydraulics analysis for the eight basins affected by the catastrophic eruption of Mount Pinatubo, The Philippines, on 15 June 1991. Approximately 5.6 billion cubic meters of medium- to fine-grained pyroclastic-flow material was deposited in the upper watershed areas around Mount Pinatubo. Rainfall-runoff has rapidly eroded eruption materials, causing lahars that have flooded low-lying areas. Flooding and sedimentation from Mount pinatubo lahars have displaced tens of thousands of people from their homes, destroyed bridges and crops, and decreased the amount of land available to agriculture in the lower basin. The analysis of this report presents the hydrology and meteorology pertinent to the design of measures to address long-term flooding and sediment control measures for all eight major river basins impacted by Mount Pinatubo.
