About this document
Unit Peak Discharge Calculation Guide by Nhan Do is a document available to read on EtoBox.
The Graphical Peak Discharge Method uses a formula to calculate peak discharge (qp) from a watershed based on unit peak discharge (qu), drainage area (Am), runoff depth (Q), and a pond and swamp adjustment factor (Fp). The procedure involves 8 steps: 1) measure drainage area, 2) calculate a curve number, 3) determine runoff depth and volume, 4) calculate time of concentration, 5) determine initial abstraction, 6) determine unit peak discharge, 7) determine pond/swamp factor, and 8) calculate peak discharge.
