* Steady-state and transient simulation

pipelinestudio improves the efficiency and accuracy of offline planning and design simulation through advanced offline simulation techniques for both natural gas and liquid pipelines. [...]

MathWorks, the makers of Matlab, released a new product that models and simulate hydraulic systems – SimHydraulics.
SimHydraulics extends Simulink with tools for modeling and simulating hydraulic power and control systems. It enables you to describe multidomain systems containing connected hydraulic and mechanical components as physical networks. It provides a representative library of hydraulic components and [...]

From Wallingford Software press release:
Wallingford Software announces that the next release of its flagship wastewater network management solution, InfoWorks CS v7.5, adds a powerful new capability for those seeking to accurately model overland urban flooding. This new feature, available this summer, produces flood mapping to represent flood depths and area of spread across the [...]

ATS-Chester developed an interface to link EPA’s EPANET software with ESRI’s ArcGIS® software (it seems that it is an old version).

Applications:

Water system modeling
Water quality management
Facility planning
GIS integration
User-friendly modeling

Features:

Developed using ESRI’s latest ArcObjects technology.
Adds a new toolbar to ArcGIS standard interface.
Allows you to create and edit your EPANET model from inside GIS.
Provides a synchronization tool to [...]

MWH Soft released InfoWater UDF, a solution for unidirectional flushing of drinking water distribution systems. InfoWater UDF delivers helps in managing the systematic flushing of water distribution systems to remove stagnant water along with mineral and sediment deposits that accumulate over time – restoring hydraulic capacity and improving water quality.
The hydraulic carrying capacity of pipes [...]

You can calculate the waterhammer in pipelines by means of the flash-application in my www site:
www.waterhammer.de.tf
My other sites could be also useful for you:

Editor’s note: The programs work online, you can contact the software author via his web-page and get a stand alone version.

From KYPipe, LLC news release:
Designed to simplify the process of sizing Hydropneumatic Tanks for pressure regulation and pump cycle control Hydropneumatic Tanks are often used to control the cycling of pumps (on-off) in systems with little storage capacity.

With no Hydropneumatic Tank in these systems the pump will be required to start and stop constantly. This [...]

The folks at Delft Hydraulics sent me a message that WANDA waterhammer program, since a few months ago can also automatically input EPANET files, thereby making it very easy to perform water hammer computations on distribution networks.
for more information see WANDA Transient web site.
