The PIPES++ program is an extended version of the PIPES program and is intended for analysis of larger town water supply systems where the user is interested in monitoring reservoir levels, pump operating times etc over an extended time period (eg 24 hours) with system demands varying with time. It also includes water quality simulation which can be used to predict how chlorine and fluoride concentrations vary with time throughout the network.
The demo version of these programs are limited to a maximum of 5 pipes and is available from the Download page. There is no limit to the size of network which the full programs will analyse.
DRAINS is a Stormwater Drainage System design and analysis program widely used in Australia and gaining recognition internationally. The demo version of this program is limited to a maximum of 5 pipes and is available from the Download page.
Users can draw drainage system components such as sub-catchments, pits, pipes, detention basins, channels and overflow routes. Several Hydrological models are available including IL-CL (the ARR 2019 preferred model), Horton ILSAX, Rational & Extended Rational Method models, and a Storage Network Routing Module that includes RORB, RAFTS and WBNM.
The DRAINS program can design and analyse stormwater drainage systems and produce summary graphs and tables, and pipe long section drawings. The image shown above is an example of the ARR 2019 1% AEP, 1 hour burst storm 6 temporal pattern including the imported NSW OEH transformational preburst rainfall to calculate Probability Neutral Burst Initial Losses (26.1mm for this storm).
DRAINS is available as a perpetual license based on the number of links in a model in the following options:
• DRAINS 20 Lite*
• DRAINS 20
• DRAINS 50
• DRAINS Unlimited
• DRAINS Unlimited Network
All DRAINS Licensing includes the ARR 2019 Initial Loss - Continuing Loss (IL-CL) and Horton (ILSAX) hydrological models, and are capable of analysing ARR 2019 temporal patterns and design procedures, including NSW OEH Probability Neutral Burst Initial Loss requirements for NSW.
A Network version of DRAINS allows the licensed number of users access to DRAINS from anywhere on your network.
* 'Lite' refers to any license without the Premium Hydraulic Model.
DRAINS solves the full unsteady flow equations in pipes, channels and overflow routes. This is useful for analysing complex surface flooding situations where storage or backwater effects occur in overflow routes, or when splitting surface flows in multiple directions via multiple outgoing overflow routes.
Pumps, weirs and orifices can be modelled as separate objects allowing for complex arrangements (e.g. multi-level orifice outlets from detention basins or pit diversion chambers, or overland flow diversions across the crown of a road). It also includes a flood mapping capability (in the DRAINS help system search for Flood Mapping for more information).
The DRAINS Lite version solves the full unsteady flow equations for pipes and channels, but only uses the Manning’s Equation for overflow routes which does not allow for back water or ponding effects.
This can be suitable for small inter-allotment style projects, or when it is clear that the Manning’s equation is adequate. Other suitable uses for the Lite version may include modelling a simple detention basin with a single low-level outlet. Weir and orifice links are not available and only a single overland flow route can be modelled leaving a pit.
There are three additional modules:
i) The Storage Network Routing Module that adds the RORB, RAFTS and WBNM storage routing hydrological models, useful when modelling large urban or rural sub-catchment areas where estimating the time of concentration with time area routing might be difficult.
ii) The GIS Module which is useful where you need to interface with GIS systems that support ESRI shapefiles or Mapinfo MID/MIF files. This module allows transfer of data and results between DRAINS and GIS.
iii) The Rational + Extended Rational Method Hydrological Module.
DRAINS come with 12 months of updates and support. Ongoing updates and support is available if required after that time.
