S02 – Rainwater run-off processes, sewer inflow and design
In this lecture, ass. prof. Ten Veldhuis discusses the rainfall aspects in Urban drainage / Sewerage. Rainfall is the largest input component of sewer systems, and large rains may result in overflow and flooding.
This lecture deals with the design parameters intensity-duration-frequency, runoff-patterns and storage capacity. The design of sewer systems is based on these parameters, using graphs (Kuiper, Veldkamp) and/or hydrodynamic models.
