Why Use xpstorm?

xpstorm provides an intuitive stormwater design program aimed at everyday stormwater design analysis and planning requirements.

xpstorm accurately represents real-life scenarios and is easy to learn. Complex algorithms work behind the scenes to produce accurate representations of stormwater quantity and quality in both urban and rural environments.

xpstorm is a link-node model that performs hydrology and hydraulics of stormwater drainage systems including automatic pipe design for the entire system or just a portion of the network. There are a large number of alternative hydrology methods available for computing storm runoff hydrographs based on input rainfall events. The hydraulics layer solves the St. Venant (unsteady flow) equations throughout the drainage network and includes modeling backwater effects, flow reversals, surcharging, looped connections, pressure flow and hydraulic jumps.

xpstorm generates flow hydrographs, flood levels, pollutant loads or concentrations and analyzes water quality control devices. The software offers all the commonly accepted methods for generating stormwater runoff and is capable of modeling and comparing multiple storm events. Choose from a variety of built-in xptables to display results, or create your own customized table.

The xpstorm solution engine utilizes a proprietary, integrated implicit dynamic wave solution technique that maximizes the solution speed along with accuracy, stability and robustness, even for steeply rising hydrographs and pumps.

xpstorm uses OLE and ODBC database connections to quickly exchange data to/from any existing hydraulic model, Asset Management database or GIS.

Many modeling processes can be executed through the use of convenient wizards that guide you every step of the way.

xpstorm is your product of choice for:

• Watershed management
• Urban land development
• Ponds and other LID/WSUD management practices
  
• Municipal Drainage

Key features within xpstorm include :

• Design/Analyze stormwater systems in either event-based or continuous mode for both the design of structures and for evaluation of asset maintenance programs
  
  
• Generate urban and rural stormwater hydrographs, taking into account all the complexities which can be experienced in steep and/or flat areas.
  
  
• Scenario Manager An easy way to examine "what if" scenarios for a single project without the need of adding redundant data. Compare model results graphically and in tables for various scenarios. A specialized scenario management tool exists also for simulating multiple storms in a single run multiple storms.
  
  
• Localization - customize the software such as the model's defaults, parameter precision and create and use templates. Many sample templates are provided that contain common data used for typical modeling applications or typical data for a municipality/region.
  
  
• Analyze multiple storms in a single run
  

• Inlet Capacity and Dual Drainage include the calculation of approach flow gutter depth, spread and velocity at capacity-limited inlets and surface ponded volumes.
  
  
• Conduit Design - design for full, partial flow, pressure flow (minimum allowable freeboard), minimum cover, multiple cells and the ability to select from a list of available pipe sizes.
  
  
• Use set up wizards global parameters, automate linking and synchronizing with GIS data
  
  
• xp2D - this option allows you to model overland flows, street flooding and river floodplains using either a 1D - 2D integrated model or a complete 2D model.
  
  
• Copy and paste results into MS Excel or any other OLE-enabled software
  
  
• Support wide range of background images including CAD, JPEG, Bitmap, TIF and ArcView shape files
  
  
• Interface with existing GIS and external databases. The purpose of the GIS link is to facilitate the import and export of modeling data from GIS and other data sources such as spreadsheets, asset management software and OLE/ODBC compliant databases.

  It also allows the inclusion of shape files as background layers and the data to be viewed and manipulated in our productive XP graphical environment. Learn more here.

• Interface with MX Roads, GEOPAK and 12d civil design packages

Here are some of the newest features of xpstorm:

• Selection of conduit shapes along with overflow paths & surface flows redirections.
  
  
• Hydrology completed according to industry standard. Rainfall intensity calculated from flexible user defined IFD tables.
  
  
• Comprehensive results for individual pipe reaches showing flow, velocity, HGL, freeboard and many more.
  
  
• Import and modify data using an advanced user definable tabular editor called xptables.
  
  
• Print and export results to scale. CAD compatible.
  
  
• Prepare construction drawings and presentation graphics in US Customary or Metric units.

xpstorm Add-on Modules

Additional add-on modules are available to further enhance the capabilities of xpstorm. Those modules are; Pumps and Orifices, Water Quality, AutoCAD, DTM, and xp2D.

DTM Module

The DTM module allows the graphical interface to create and contain an embedded digital terrain model (DTM) or surface model. The embedded triangular irregular network (TIN) can be created from manhole elevations, a file containing a series of X Y Z and (optional) string data or directly read from popular terrain modeling packages.

With the surface model incorporated into the project the user can create perspective views, drape geo-referenced images, obtain ground elevations automatically for nodes, cut cross sections for natural channels and view flooded results in 3D.

xp2D Module

A powerful feature of xpstorm with the 2D module is its ability to dynamically link to any 1D model in an integrated fashion. The user sets up the model as a combination of 1D network linked to 2D domains as a single model.

xp2D is based on the TUFLOW program developed by WBM Oceanics Australia and The University of Queensland. TUFLOW has been the subject of extensive testing and validation. It is specifically orientated towards establishing the flow patterns in coast waters, estuaries, rivers, floodplains and urban areas where the flow patterns are essentially 2D in nature and would be awkward to represent using a 1D model.

xpstorm has incorporated the TUFLOW engine into a user-friendly graphical interface that guides the user through preprocessing of input data and the calculation of the model. All of xpstorm's familiar tools for generating tables, graphs, and animations are available for reviewing, analyzing and presenting model results. New 2D and 3D animation tools make it easy to present results to managers and decision makers.
