This presentation explores a fundamental technique used in all hydrology evaluations, and assesses standard methods used to estimate the time it takes rainfall runoff to travel for specific watershed characteristics. We will compare Manning’s sheet flow coefficients with watershed percent impervious surface, rational method coefficients, and NRCS’s soil curve numbers.
Learn how to provide more efficient storm water management designs through discussions on an important hydrology variable that affects storm water drainage pipe sizes, storm water storage volumes, storm water ditch sizes
