Important announcement

Dear visitor,

Please note that this OpenCourseWare platform will be replaced at the end of 2026 by a new platform (under the same url ocw.tudelft.nl).

Courses and their contents that are currently available the platform will partly be migrated. URL’s for this content will change and content might be unavailable for some time. In addition, some courses will not be available anymore.

If you are linking to specific courses on this platform (for instance for your students), please take timely measures to avoid problems with access. Possible actions are:

  • Download the materials to your local platform (laptop, server)
  • For educators only (including TU Delft lecturers): Contact us at ocw@tudelft.nl and inform us what course you are using in what context (institute, program, period of use, number of students). We will research (in collaboration with the authors of the course) and decide if we will migrate the course, and if yes, can supply you with a new url.

Thank you.

S02 – Rainwater run-off processes, sewer inflow and design

Course subject(s) 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.
