This study evaluated the catchment and flood prone area by applying physical and numerical modeling. This described rainfall data and presented evidences of flooding based from extreme precipitation events. Mathematical models were derived using the definition of discharge and Manning’s formula which finally were used to estimate the sufficiency of the river canal cross sectional area to transport great amount of water flow. Mt. Isarog, mountain ranges of Lagonoy and the low land area are the sources of flood water in Lagonoy River. The amount of daily precipitation is always insufficient to induce flooding except for a terrifying event that the area was heavily affected. The river canal cross sectional area is sufficient to accommodate flood water flow but the position of the moon which is indicating differences on river depth during full/new moon and first/third quartermoon, high tide and low tide, and with heavy and non-heavy rainfall.causes the flood while others are due to river bends, insufficient design of spillway and obstruction of irrigation waterway.
