Files for a number of short examples are located in the folders C:\ProgramData\Drains, in folders named 'LiteExamples' and 'FullUnsteadyExamples' (C:\ProgramData\Drains may not be visible because it is often hidden in Windows. To make it visible, from File Explorer select the 'View' tab and tick the 'Show Hidden Items' box).
The 'LiteExamples' and 'FullUnsteadyExamples' files can all be run in the Demonstration or Demo Version of DRAINS. This version has all the features of the full program, but cannot model more that five pipes or open channels, five sub-catchments and one irregular open channel link. There are also limitations on the changes that can be made to detention basins, culverts and storage routing models.
The examples are divided into ones that run with the DRAINS Lite hydraulic model and those that require the Full unsteady hydraulic model. The Lite model applies unsteady flow hydraulics to pipe and open channel flows, with simpler calculations for overflow routes. The Full unsteady model applies unsteady hydraulic modelling to overflow routes and has special components for modelling complex detention basin operations.
The Lite hydraulic model examples are:
- Gymea street drainage system design using Horton (ILSAX) hydrology and 2019 procedures
- Gymea street drainage system design using extended rational method (ERM) hydrology
- Gymea design using rational method with ARR 1987 and ARR 2019 rainfall data
- Major/minor design for a small street drainage system at Gymea, NSW, using an IL-CL model and lite hydraulic calculations
- Gymea street drainage system run with selected individual storms
- Penrith ARR 1987 street drainage system example
- Sydney on-site stormwater detention system example
- An established drainage system at Beenleigh, Queensland
- A mixed pipe and open channel system at Bendigo, Victoria
- Open channel system with a culvert and bridge at Bowen, Queensland
- Rural catchment at Shepparton, Victoria, modelled using RORB hydrology
- A model mixing Horton (ILSAX) and WBNM hydrology models at Bowral, NSW
- Rational method pipe design for Pine Rivers Area, Queensland, with upstream flow paths
- Property drainage example at Merimbulah, NSW with roof drainage and OSD tank
- Rural town drainage using swales and channels at Blackstump
After looking through the examples, you can investigate DRAINS further by varying the data specified in the examples or by creating examples of your own, within the limits imposed in this demonstration version.
