From 1998 - XP Software 20 years of water resource software experience


XP Software 20 years of water resource software experience

XP Software is one of the longest established water resource software
organisations in the world. Having started operations in 1974 with the development of the Regional Stormwater Model (RSWM), a rainfall/ runoff networked program for simulating stormwater runoff, XP Software has had a long tradition in the development, marketing and support of water resource software. The RSWM, or RAFTS program as it was later retitled, is still in use today by over 400 organisations. Currently over 2000 organisations, ranging from a few staff to over 5000, around the world are licensed users of software marketed by XP Software.
Approximately 50
organisations are currently licensed with XP Software products in New Zealand. At this time software is
distributed to New Zealand directly from Australia with support via phone, fax, e-mail and web facilities. Workshops are provided on specific software with the most recent being a two-day, hands-on workshop focusing on XP-SWMM in Auckland which was conducted in March 1998.
It is expected that regular workshops and user forums will play a major role in the future with the increasing acceptance of the XP-SWMM and XP-UDD software programs throughout New Zealand

XP Software has been involved in the full ambit of software and hardware trends since the early 1970s. This started with main frame computers using Unix type operating systems, through to the early phases of the Apple Macintosh, up to the current dominance of PCs utilising Microsoft's DOS, Windows 3, 95, 98 and NT operating systems.
To better respond to ever increasing changes XP Software's North American office has recently merged with Caice Software, a leading civil engineering software developer specialising in digital terrain, road and civil design, survey and Geographical Information Systems integration. Development is well advanced to integrate parts of our respective software packages to greatly improve the productivity of many of our users throughout the world.
XP Software's global approach, which utilises partners currently in Australia, North America, France and Japan, is allowing XP Software to be at the leading edge of water resource software with rapidly evolving associated management systems including GIS, FIS, SCADA and Asset Management Systems. Integration with our Caice partners in North America also allows a far more efficient system by tying together both road and site design with advanced stormwater and wastewater management within a common software package and database.
XP-SWMM/UDD is a truly integrated management tool developed to allow a holistic approach to the analysis or design of stormwater and wastewater systems including combined systems.
Modules are available within the stormwater areas to estimate either design floods or simulate historical events including both water quantity and quality. Both urban and rural or mixed areas can also be modelled. Within the wastewater elements both dry weather and wet weather flow can be estimated. Treatment models are included to treat wastewater through traditional treatment plants as well as both point and non-point source pollutants from stormwater through less traditional wetlands, gross pollutant traps and water quality control ponds.
XP-SWMM provides world best practice hydraulic modelling to simulate the transport of flows, including pollutants, throughout the drainage network.
The hydraulic model also allows the combined use of both open and closed conduits. This is particularly useful in urban stormwater involving both underground pipes as well as on ground surcharge facilities including roads and channels.

Building Sewer Collection System models using InfoSewer

Building Sewer Collection System models using InfoSewer

InfoSewer is developed to take full advantage of the capabilities of GIS and relational database management systems (RDBMS) technology. By embedding GIS mapping functions and utilizing proven and efficient tools for information exchange and graphical data entry, maintenance and display, InfoSewer provides the user with an efficient easy-to-use vehicle for network model construction and management.

 

In InfoSewer , a sanitary and storm sewer collection system model consists of two major components:

 

   Network schematic - The network schematic provides a critical role as a model input, providing information on the connectivity, length, and shape of network components and it also plays an important role in the display and analysis of model results, acting as the vehicle for results presentation.

Modeling attributes - Information associated with network elements act as the primary input to the hydraulic network simulator. This information includes a set of required attributes describing critical components of system operations and a set of user-defined attributes for integration with other infrastructure management applications.

 

InfoSewer stores the network schematic and modeling attributes in GIS Shapefile and DBF format. It provides the following tools to build and maintain sewer collection system models.

Head loss due to Transitions and Fittings (Local loss) for InfoSWMM and SWMM5

Head loss due to Transitions and Fittings (Local loss)
Whenever flow velocity changes direction or magnitude in a conduit (e.g., at fittings, bends, and other appurtenances) added turbulence is induced. The energy associated with that turbulence is eventually dissipated into heat that produces a minor head loss, or local (or form) loss. The local (minor) loss associated with a particular fitting can be evaluated by
                                                                                                      
where   V         =          mean velocity in the conduit (m/s, ft/s)
                K         =          loss coefficient for the particular fitting involved.
The table given below provides the loss coefficients (K) for various transitions and fittings.

Subcatchment Width
Characteristic width of the Subcatchment (feet or meters).
Subcatchment Slope
(%) Slope of the Subcatchment.
