Water Simulation Packages (WSP)

AquiferTest Pro v.3.5 is the latest software technology for graphical analysis and reporting of pumping test and slug data. This powerful yet easy-to-use program has everything you need to quickly and easily calculate the hydraulic properties of your aquifer using a comprehensive selection of pumping test and slug test solution methods for:

• Confined aquifers
• Unconfined aquifers
• Leaky aquifers
• Fractured rock aquifers

AquiferTest Pro 3.5 now includes 6 powerful forward/predictive solution methods. Forward solutions, also known as predictive analyses, represent a new methodology for analyzing pumping test data. Instead of matching field data (observed draw-down data) to a given set of curves, forward solutions allow you to calculate water levels/drawdown at any given point, based on estimated transmissivity and storativity. This allows you to

• Optimize planning for future pumping well locations
• Develop more effective pumping rates and durations
• Understand the effects of well interference
• Improve the design of pumping tests

ADS Environmental Services announces the release of their newest software Profile 3.0:

This powerful desktop software tool is an intelligent data manager that is easy to use and contains unsurpassed analytical tools. Designed for configuring, collecting, diagnosing, analyzing, and reporting flow and rainfall data from FlowSharkÔ and other ADS monitors, it will also import data in CSV or Excel formats from most other meters.

Sneak peak at features of this desktop software:

• Profile 3.0 contains graphical analysis tools (Hydrograph & scattergraph) which allow on-screen editing of data. This saves time and improves data quality.
• Profile 3.0 is a desktop data warehouse which allows importing and exporting of data from other sources. This allows the user to house all data from a flow monitoring project in one location for analysis and reporting.
• The user has the ability to schedule collection of data, changing time in meters, printing reports through the use of scheduled services.
• Diagnostic and collect tools are in the same software package which saves time and prevents loss of data.
• Site Dr.analysis is provided following collects in diagnostics, which aids the field person in trouble shooting monitor problems.
• Provides the ability to “snap” velocity data points to a user defined pipe curve, which enables the user to make estimates when data is missing or flagged. This means less downtime and data is available for analysis. It saves time since the user does not have to use external spreadsheets for estimating missing data.
• Ability to view several sites on one graph, allowing u/s & d/s comparisons. This aids in system wide balancing and gives the user the ability to draw conclusions from the data, e.g. rule out faulty equipment.
• Profile contains functions for block editing of data, e.g. flagging data points above a preset level improving data quality and allowing some standardized editing practices.
• Collects are performed via TCP/IP, modem or serially.
• Collection of FlowSharks via a Telog 33-Ru is available.

If you decide that you want to download the files please drop me a note and I will send you the ftp information. I do not publish it here to avoid security risks.

Update: Eelco van Beek, one of the books authors updated me that they had to close the FTP-site because hackers got hold of it. The good news is that now the book can be ordered from the web-site of UNESCO-Publishing (20% off the regular price if you order by the end of April 2006 - €40). The book can be also downloaded, as one file or a set of smaller files, from Delft web-site.

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 action places unnecessary stress on the pumps, consumes more electricity and produces pressure transients that can damage both the pumps and piping system. In addition the pump’s life will be considerably reduced.

By adding storage capacity (hydropneumatic tanks) the number of pump starts and stops can be minimized. Pumps will last much longer with greatly improved operations and reliability.

From MWH Soft press release:

MWH Soft announced the worldwide release of InfoSWMM Designer for ArcGIS. As a full-featured urban drainage network analysis and design program, InfoSWMM delivers the highest rate of return in the industry. All operations of a typical sewer system - from analysis and design to management functions like water quality assessment, pollution prediction, urban flooding, real-time control and record keeping - are addressed in a single, fully integrated geoengineering environment. The program gives users unprecedented strength in managing urban runoff and wet weather water quality problems in combined, sanitary and storm sewers, optimizing BMP and LID designs, and meeting SSO and CSO regulations.

For more information see MWH Soft web site.

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.

To those of you interested in SCADA systems please have a look at the new SCADA blog.

This web site was started on December 2004 and now it is one year old. During this year I have tried to find all most of the water simulation packages available.

Judging from the popularity of the posts here EPANET is the most requested item and the DXF2EPA is the most popular tool. Another popular service is the EPANET User-List archive.

I would like to wish all of you a happy new year and all the best

From CIVIL DESIGNER web page:

Civil Designer is the design system created by civil engineers for civil engineers. Water is a powerful, yet easy to use module for the analysis and extended time simulation of fluid handling networks consisting of pipes, valves, reservoirs and pump stations.

With the Water module you can:

• Import data from various sources such as ASCII tables, spreadsheets, dBase or MS Access tables as well as DWG/DXF files.
• Graphical interaction allows you to easily insert nodes and links, make changes to an existing layout by moving a node, change the flow direction, and query or edit a link with a click of the mouse.
• View the network with a bitmap or cadastral backdrop, or display the site contours and slope shading to decide on optimum network layout.
• Analyse suburbs separately and combine new and existing models to simulate the complex system of networks that are often found in modern towns and cities. The comprehensive network design will take into account the relationship between different branches.
• Time-based demand patterns may be defined for different categories of water usage. Each draw-off point may have a different demand pattern.
• The impact of extensions to the network, increased demand, imposition of water restrictions, power failures, major pipe breaks and empty reservoir conditions may be readily determined.
• Attach external water consumption tables and compare the measured usage to the modelled consumption to calibrate the demand or identify problem areas in the network.
• Up to 8 pumps may be handled in each pump station. The pumps are configured in parallel and may be controlled by pressure, water level or be time-based (on/off at certain times).
• Valves may be controlled manually, by pressure, by flow, or by level. Reservoirs may have any shape — you can select one of the most common shapes or define the water depth versus volume for a particular reservoir.
• Display the results of an analysis graphically by colour according to calculated results, in tables, or on time-based curves.
• Generate long sections with the ground profile automatically extracted from the supporting digital terrain model.
