Chapter 8 Open Channels January 2016 Urban Drainage and Flood Control District 8-1 Urban Storm Drainage Criteria Manual Volume 1 . 1.0 Introduction . This chapter focuses on the preservation, enhancement, and restoration of stream corridors as well as the design of constructed channels and swales using natural concepts. In drainage systems there are many examples of design that provides far greater potential to house bacteria, in particular metal to metal joints. Given that the average bacterium is in the order of 1–3 μm in length, a metal-to-metal contact point, typically 20 μm, can admit copious bacteria whilst also preventing effective cleaning.

2.2. Analysis of flooding phenomena. Flooding in urban drainage systems as defined above may occur at different stages of hydraulic surcharge depending on the drainage system (separate or combined sewers), general drainage design characteristics as well as specific local constraints.
