The Lite and Full Unsteady Hydraulic Models
(a) Introduction Introduced in 2010, the Standard and Premium hydraulic model procedures superseded the Basic hydraulic model that had been applied in DRAINS since its first release. In 2020 the Standard hydraulic model was renamed to Lite hydraulic ...
Updating existing DRAINS models
The ARR 2019 initial loss - continuing loss model and the associated ensembles of design rainfalls can be added to existing DRAINS models using Horton (ILSAX) or the ERM. Rational method models can be updated or created using the procedure outlined ...
Storage routing models
(a) General As well as the standard Horton (ILSAX) hydrological model for simulating flows from urban areas, DRAINS has optional storage routing models based on procedures applied in three hydrological models that have been used in Australia since ...
DRAINS Examples

Hydraulic grade line analysis
This is a form of hydraulic analysis of piped drainage systems that traces the positions of hydraulic grade lines throughout the system. It is usually applied as a steady state model, calculating HGLs for the peak flowrates at each pipe in a system. ...
