34 What is the Curve Number For Porous Pavement? Who wants to know?!? (What is your OBJECTIVE?) 34
35 The SCS (NRCS) Curve Number Originally conceived to translate rainfall depth into runoff depth on agricultural watersheds method worked best for large storms This was then translated into a runoff hydrograph 35
36 SCS Dimensionless Unit Hydrograph Area under hydrograph is the runoff volume Divide runoff volume by watershed area = runoff depth 36
37 Methods of Teasing CN from the Data Measure P and Q, invert basic SCS equation Measure P and outflow hydrograph h (q), measure lag, estimate CN from lag equations Measure Q and q p, estimate CN from peak discharge equations 37
