Introduction to DRAINS
This first workshop is normally intended for persons who are just beginning to use the DRAINS program. It is meant to get them started and to know where to obtain necessary information. It also provides a refresher for experienced professionals who have not used DRAINS for some time.
However, with the finalisation of ARR 2016 there will be added material on the new initial loss – continuing loss urban model and the pipe design procedure using rainfall ensembles. There will be a brief outline of detention systems.
It is suitable for civil engineers and related professionals who will be using DRAINS, and assumes no prior knowledge. While the workshop’s basic aim is to train participants to use DRAINS, it covers the background to the use of DRAINS in designing stormwater drainage systems, and many of the complexities that a designer will encounter.
- An overview of design procedures,
- DRAINS – how to navigate its interface,
- Installation and updating,
- An example of a pipe design model, setting up, running a model, and reviewing results,
- New 2016 I-F-D’s from the Bureau of Meteorology and temporal patterns from the ARR Data Hub,
- Step-by-step construction of a DRAINS model using the ARR 2016 design procedures,
- Exercises involving building models (with solutions),
- Available hydrological models, including ARR 2016 initial and continuing losses, ILSAX and rational method models,
- An example of a DRAINS model that includes open channels and detention basins,
- A brief review of on-site stormwater detention systems, and
- Information on (a) pit pressure change coefficient calculations, (b) pre- and post-processing spreadsheets and (c) the DRAINS Manual and Help system.
The workshop equips participants with:
- the ability to set up DRAINS models for design of street and property drainage systems,
- an awareness of design rules and advanced aspects of DRAINS, and
- knowledge of how to obtain further information.
