tsnet conducts transient simulation using MOC method for water distribution systems.

Project description Documentation Status PyPI - Downloads GitHub license GitHub (Pre-)Release Date

TSNet performs transient simulation in water networks using Method of Characteristics (MOC).


A number of commercial software for transient simulation in water distribution systems are available in the market; however, the use of these software for research purposes is limited. The major restriction is due to the fact that the programs are packed as black boxes, and the source code is not visible, thus prohibiting any changes, including modification of existing and implementation of new elements, in the source code. Therefore, the authors find it imperative to develop an open source package rendering easiness for interaction, modification, and extension.


TSNet is a Python package designed to perform transient simulation in water distribution networks. The software includes capabilities to:

  • Create water network models based on .inp files
  • Generate transient events by operating valves and pumps
  • Add disruptive events including pipe bursts and leakages
  • Add surge protection devices
  • Choose between steady,quasi-steady, and unsteady friction models
  • Perform transient simulation using MOC method
  • Visualize results
