REALM is a Windows-based computer program that can simulate the operation of both urban and rural water supply systems during droughts as well as during periods of normal and high streamflows.
REALM is a computer program that can simulate simple water supply systems as well as large and complex ones such as the Goulburn irrigation system in south-eastern Australia.
REALM is distributed as public domain software and can be downloaded for free. REALM was developed more than 20 years ago and is being superseded by Source. See the transition here.
This webpage provides the most updated user manuals and files.
In 2022, REALM will be retired and as such, these resources will no longer be updated. Nonetheless, the files provided on this webpage are the latest as of January 2022. These files reflect the accumulation of decades of development in REALM software.
