Water Simulation Packages (WSP)

From Pipeflow Software web site:

A wide range of hydraulic engineering problems can be solved with Net-Pipe steady-state simulation and unsteady-state simulation: Water-hammer studies for hydroelectric power plants, analyses of surge pressure alleviation for oil pipelines, layout studies for pipe installations, or capacity calculations for water distribution networks, to name a few. Net-Pipe is designed for the hydraulic engineer and for the technical specialist with a background in fluid mechanics.

You can use Microsoft Visio to drag-and-drop the pipe network elements from a customized stencil containing the Net-Pipe hydraulic elements:

Following the cal for the Special JWRPM Issue on Drinking Water Distribution Systems Security, Avi Ostfeld sent the information regarding the “Battle of the Sensors”:

Dear Colleagues,

Following my announcement of yesterday on a Special Issue of the Journal of Water Resources Planning and Management on Drinking Water Distribution Systems Security, here are a few more details on the “Battle of the Sensors” manuscript: the basic idea is to compare and discuss different published methodologies (i.e., published either in a journal, conference, or as a report so that an accessible reference can be quoted) for sensors/monitoring allocations using a well defined example (e.g., EPANET Example 3). Each of the participants will get the “rules” of the “Battle” (actually it’s not really a Battle; it’s more a comparison. The name “Battle” is induced from the Battle of the Networks paper of Walski et al., 1987) and will need to return (to me) with a short description of his recommendation as of where to put the sensors, the objective function he used, the detection likelihood of the sensors to reveal a contaminant intrusion, etc. I will receive all the reports and put them together: first each as a stand alone entity, and then as an ensemble looking at the differences between the methodologies, discuss their advantages and limitations, and suggest future directions. The next stage will be to send back the paper to all the participants for their approval and comments. Once I receive back all the comments I will submit the paper to the JWRPLM Chief Editor to perform the regular review process. I anticipate that the probability of such a paper to be rejected is very low. In addition, since we are looking at a single manuscript we are bounded by the 10000 equivalent word limitation of the journal so each of the participants will have a limited space. I hope this puts more light on the exercise which I anticipate to be very interesting. If any of you would like to participate, please let me know by June 7, 2005. Once have the list I will define exactly the “rules”, set the timeline, and distribute.

Thanks, Avi.

The following call was received form Dr. Avi Ostfeld:

Dear Colleagues,

Following the EWRI conference in Anchorage, Alaska, May 15-19, 2005, and the growing interest in water distribution systems security, a special issue of the Journal of Water Resources Planning and Management on Drinking Water Distribution Systems Security has been approved. The special JWRPM issue is tentatively scheduled to appear July/August 2006.

The major themes of the issue will be: sensors/monitoring stations allocations; disinfectant residuals control; contaminant inverse modeling methodologies; pollutants containment; case studies implementations; and a “Battle of the Sensors” exercise.

The manuscripts will be peer-reviewed with the normal rigor of any standard submittal to the JWRPM, but on an accelerated schedule as outlined below:

June 1, 2005: Final date for authors to express their interest in submitting a paper to the special issue by providing a manuscript title and authors names; and in participating at the “Battle of the Sensors” exercise [sent to Avi Ostfeld (ostfeld@tx.technion.ac.il)]
Aug 1, 2005: Final date for authors to submit 1st draft of paper (pdf to Ostfeld)
Sep 20, 2005: Provide 1st round review comments to authors, including preliminary decision
Nov 1, 2005: Final date for authors to submit 2nd draft of paper
Nov 25, 2005: Provide 2nd round review comments to authors, including final decision
Dec 15, 2005: Final date for authors to submit final version of accepted manuscript (pdf to Ostfeld)
Dec 31, 2005: Editor sends approved final versions to ASCE for copyediting

Please forward this message to any additional authors who might be interested in this initiative.

Sincerely yours,

Avi Ostfeld
Associate Editor, JWRPM

From HydroCAD web site:

HydroCAD-7 is a Computer Aided Design tool used by Civil Engineers for modeling stormwater runoff. HydroCAD provides a wide range of commonly used drainage calculations including:

• SCS, NRCS, SBUH runoff hydrographs
• Rational Method with automatic IDF curves
• Hydrograph routing through ponds & reaches
• Coupled ponds with automatic tailwater
• Automatic hydraulics and culvert calculations
• Automatic pond storage calculations, including embedded storage chambers
• Easy management of multiple rainfall events

HydroCAD is ideal for studies using the TR-20, TR-55, or SBUH methods. HydroCAD provides a wide range of standard H&H techniques in an easy-to-use graphical form, managed by the on-screen routing diagram we pioneered in 1986.

From HYDRA web site:

HYDRA® software is a full-featured program used by environmental and civil engineers to model and design urban drainage systems. It helps you estimate wastewater flows, and then calculates the resulting hydraulics within the collection system. It provides tools for managing all types of flows, including sanitary wastewater, stormwater inflow, rainfall-dependent infiltration, and groundwater infiltration. It helps you understand how the whole sewer system works under various conditions — today and in the future - and identify potential problem areas. HYDRA® software creates preliminary design for new sewers and suggests improvements for existing systems. It helps you optimize your pipe network, and find the most cost-effective way to solve system problems. The HYDRA® program has been used by thousands of engineers since its first commercial release in 1973.

4/27/2005 Cincinnati, OH - Civil and environmental engineers now have an improved software tool, the Storm Water Management Model (SWMM), to help plan, analyze, and design urban storm water drainage and sewer systems. This latest revision to SWMM includes several improvements not available in previous editions. These include a modern graphical user interface, a more intuitive modeling approach, and improved computational speed. SWMM continues to be open source and its numerical engine can easily be integrated into third-party interfaces.
