Hydraulic characteristics of siphonic roof drainage outlets

open access: yes
Siphonic roof drainage uses an innovative hydraulic design to increase the efficiency ofrainwater disposal. The roof outlet is a critical component of the system and not onlypromotes and sustains priming of the system but also controls the depth of ...

Modelling of unsteady flow in siphonic roof harvesting system

open access: yes
Siphonic roof drainage systems have been in existence for more than 40 years and are becoming an increasingly common element of urban drainage infrastructure. A siphonic system allows roof runoff to quickly reach its maximum flowrate.

Design of siphonic rainwater drainage system

open access: yes
Today, conventional systems are commonly used for roof rainwater drainage. In recent years, the use of siphonic drainage systems has become widespread, based on the principle that the pipes are full flow.

Aeration and gutter water levels in siphonic roof drainage systems

open access: yes
An investigation is presented into how negative system pressures, the degree of aeration, and gutter water levels are affected by the number of outlets in a siphonic roof drainage system.

Measuring Flows in Partially-Filled Pipes in Siphonic Roof Drainage Systems * 1

open access: yes, 2011
While a variety of flow measurement devices are available to measure the flow of water through closed pipe systems, these devices generally only function correctly when the pipes Introduction design capacity.
