XPSWMM Modules

xp2D

xp2D gives you the power to analyze and predict potential flood extents, depth and velocity and accurately model the interaction of surface and underground systems in an integrated 1D/2D modeling environment. The software can also be effectively used to simulate and analyze tidal surges, dam breaks and breaches on sewer networks.

xp2D simulates the complex hydrodynamics of floods and tides using the full 1D St. Venant equations and the full 2D free-surface shallow water equations.

In addition, xp2D is an excellent tool to evaluate flood hazards and evacuation route time to inundation.

Multiple Domain for xp2D

The Multiple Domain add-on feature for xp2D allows you to more efficiently utilize your 2D cells, and provides a way to focus analysis where it is needed most.  It allows several domains to be added to a single model, each with its own grid extents, time step, grid cell sizes and orientation.

Multiple 2D Domains are often used to reduce the number of cells in a 2D modeling project. Large cell sizes are used in areas where fine detail is not required or where a large area is to be modeled. Small grid sizes provide more detailed analysis of varying terrain, channels and urban areas.

For example, a cell size of 1-2 meters could be used for the flow in a narrow channel of say 10m wide and then a separate 2D grid of 10 meters could be used for a nearby floodplain. Flow from one 2D Domain can be joined to another with the 2D/2D Interface polyline tool that exchanges flows between the two distinct 2D Grid Extents.

xpviewer Encryptor: Make Submitting Models for Review Easier

With xpviewer Reader, your clients and other stakeholders associated with your project will have the ability to view and interrogate an encrypted version of your xpswmm models. The xpviewer program allows all software functions except the ability to change, export and solve the model. Therefore your stakeholders can view model animations, query and print the model results and participate in the model development and approval process without being required to purchase a license from XP Solutions.

This is an excellent tool for those customers who wish to share their model with others within or without the organization who do not already own a license of the software, but wish to view the model(s) results. Since the model cannot be changed or resolved with xpviewer Reader the integrity and security of the created model is preserved. 

It is also excellent for reviewing agencies who wish to view and query every element of a model and its results but don't wish to take on the modeling work itself.

Real Time Control

Real Time Control (RTC) elements such as regulators, bendable weirs, and telemetry-controlled pumps are part of xpswmm. These hydraulic elements allow changes to model elements in real time (evaluated at every time step) based on defined depths of flow in any node in the model. Many control strategies can be evaluated in the program by using a combination of rating curves and these RTC elements. However, complex situations involving multiple sensors and Boolean logic are only possible by expanding xpswmm with our RTC add-on module. This powerful add-on module extends the existing depth-only RTC to a comprehensive management and design tool.

The RTC sensors can also include any combination of date/time, velocity, flow and water levels and depths at nodes, conduits, pumps, orifices, and weirs. The values of the sensors can be compared to static values and with each other using typical Boolean logic and mathematical operators. For example, a control can be activated if the water level in location A is greater than location B by 2.3 feet.

Numerous hydraulic parameters depend on the type of object being controlled. The parameters that can be modified include: flow, roughness, diameter, water depths, pump on/off levels, well volume and speed factor, weir crest and surface elevation, discharge coefficient and length, and orifice area coefficient.

Additional control properties include Start and Stop time of the control, ramp times and maximum and minimum values. Operators can be concatenated with Boolean operators, and parameters can be compared with other sensors or with absolute values. Real time control can be activated during certain hours of the day, odd/even days, days of the week, months of the year and control can turn on and/or off over a user-defined time period.

xpwspg

WSPG (Water Surface Profile Gradient) is a hydraulic analysis that computes uniform and non-uniform steady flow water surface profiles and pressure gradients in a network of open channels and closed conduits. This tool, originally developed by Los Angeles County, has been upgraded by XP Solutions and is available as an add-on module to xpswmm or as a separate standalone product called xpwspg.

Applications include engineered channel design, urban drainage analysis and minor hydraulic loss analysis.

After designing the model using the steady state WSPG solution, the model can be switched to a full dynamic analysis in xpswmm. This combination of solutions allows the modeler to have confidence that the proposed design maintains the hydraulic grade line to acceptable levels and that storage facilities are sized correctly for major events.
