In Legaspi City. Albay with 50-year return period. The watershed area is 10 km2 and the sheet flow covers running length of 8 km. The highest point in the watershed is 90 masl and the drainage outlet elevation is 30 masl. RIDF parameter for Legaspi City: a-522 b-176 N-0.50 K-10 Using the solved rainfall intensity, estimate the corresponding peak runoff rate in m/s using rational formula. Runoff coefficient is 80%.
