Advantica proudly announces the release of SynerGEE ֲ®Water 4.1, featuring a significant set of enhancements and additions for water distribution network simulation:
SynerGEE 4.1 offers practical base map advancements that allow users to import external geospatial information system (GIS )source data into the SynerGEE modeling environment. Building up on the basemapping feature and polyline con version functionality introduced in SynerGEE 4.0,the basemap conversion tool lets users not only view the basemap behind the model, but also convert multiple pipe and facility layers into a model simultaneously, integrate external source data into SynerGEE and save basemap attributes using existing names and settings.
The new version also features a reverse facility orientation tool that enables users to switch the direction of model facilities that have been placed in to a model from an external source incorrectly .The tool ג€flipsג€unidirectional facilities, including check valves, regulators and pumps, mistakenly positioned backward in the simulation.
From GAEA Technologies web site:
We are very pleased to announce that WinLoG Version 4 has been released. This upgrade has taken over two years to develop and represents the culmination of many of our users and internal ideas for enhancements.
The geographical information system feature added in version 4 displays a location map for the project showing the boreholes, cross-sections, and any surface features. This feature makes it easy to visualize your project and can be used to print a location map of the project. To edit a borehole all you need to do is click on it in the location map.

The following information was received from Innovative Hydraulics:
What is Visual Hydraulics?
Visual Hydraulics is a state of the art, flexible hydraulic analysis tool. It is used primarily for modeling the hydraulic characteristics of water and wastewater treatment plants, and is capable of analyzing entire hydraulic profiles. The program follows the traditional method for analyzing water surface profiles: a downstream control point is selected, and the hydraulic profile is then determined upstream of that control point.
What can Visual Hydraulics model?
Visual Hydraulics covers most of the hydraulic features typically encountered in a treatment plant application. A user may analyze the following features: full flow pipes, open channels (rectangular, trapezoidal, triangular, circular), tanks, orifice/baffle/gate(s), weirs (v-notch, rectangular, sharp crested, Cipolletti, contracted, and broad crested), flumes (Parshall, rectangular, trapezoidal, cutthroat), racks/screening devices, tank launders, filter media, contraction/enlargements, and Venturi meters. Submerged weir and flume analysis is also included.

Back in May 2001, Lewis Rossman, author of EPANET, released a small utility to convert dxf files to EPANET format. After a little time he announced that the EPA will not continue to distribute and support the utility.
A few days ago I found the file in my old computer and thought that people may find it useful. So here is a short description form the utility manual and a download link:
“DXF2EPA is a Windows utility program that converts a line drawing of a pipe network stored in Autodesk’s DXF file format into an input data file that can be read by the EPANET water distribution system analysis program. It converts all of the line and polyline elements in selected layers of the DXF drawing into a set of pipes and junctions for EPANET, with all coordinates and vertex points intact. Additional elements, such as reservoirs, tanks, pumps, and valves, have to be added to the EPANET model by hand. Although the conversion program can compute pipe lengths if so desired, other network data, such as junction elevations and demands, and pipe diameters and roughness values have to be edited within EPANET after the converted file is loaded.”
The US Army Corps of Engineers announced the release of HEC-RAS 3.1.3.
The HEC-RAS modeling system was developed as a part of the Hydrologic Engineering Center’s “Next Generation” (NexGen) of hydrologic engineering software. The NexGen project encompasses several aspects of hydrologic engineering, including: rainfall-runoff analysis; river hydraulics; reservoir system simulation; flood damage analysis; and real-time river forecasting for reservoir operations.
The HEC-RAS system will ultimately contain three one-dimensional hydraulic analysis components for:
(1) steady flow water surface profile computations;
(2) unsteady flow simulation;
(3) movable boundary sediment transport computations.
Currently steady and unsteady flow are available and sediment transport is under development. A key element is that all three components will use a common geometric data representation and common geometric and hydraulic computation routines. In addition to the three hydraulic analysis components, the system contains several hydraulic design features that can be invoked once the basic water surface profiles are computed, including bridge scour computations, uniform flow computations, stable channel design, and sediment transport capacity.
The current version of HEC-RAS supports steady and unsteady flow water surface profile calculations. New features and additional capabilities will be added in future releases.
For more information and download see HEC-RAS web page.
Manuel Lֳ³pez-Ibֳ¡ֳ±ez, currently at the School of the Built Environment of Napier University in Edinburgh (UK), adapted the EPANET Toolkit version 2.00.10 to GNU/Linux.
A number of new features were added:
ENgetlinkvalue()ENgetnodevalue() can return the initial (EN_INITVOL) and current volume (EN_VOLUME) of a tank.ENgetcount() returns the number of pumps and the number of reservoirs in the network.ENgetcount(EN_CONTROLCOUNT, &count), a control may be added dynamically calling ENsetcontrol() with cindex = count + 1New toolkit functions:
ENgettotalenergycost() : calculates total energy cost per pump plus demand cost.ENgetpumpswitches() : number of switches of a pump.ENaddleveltrig() : adds rule with the following formatIF SYSTEM CLOCKTIME >= start_time (in seconds)
AND SYSTEM CLOCKTIME < stop_time (in seconds)
AND TANK id(tank_index) LEVEL [BELOW|ABOVE] level
THEN PUMP id(pump_index) STATUS IS status
ENgetminstoptime() : returns the shortest time interval (in seconds) that a certain pump was not active.ENgettankindex() and ENgetpumpindex() : allow to find a pump or tank without knowing its id or index.ENaddpattern() adds a new pattern to the database.This version is highly experimental but Manuel is doing a serious effort to document the changes. He is using a Control Version System (CVS) to keep track of the development, so this version is open to contributions from anyone. Manuel is hoping to obtain feedback in the form of code, testing, reports, acknowledge or just complains. 🙂

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.
