XP Software, a provider of hydrology and hydraulics software products, now offers two-dimensional (2D) modeling, a major enhancement to its flagship product xpswmm.
“Engineers can now utilize embedded digital terrain modeling (DTM), and a proven 2D hydrodynamic modeling engine with xpswmm’s traditional 1D modeling in a single environment,” said Tony Kuch, Vice President of Software Applications. “It allows the modeler to reliably evaluate the extent of urban and rural flooding in a visually appealing way that even non-technical observers can appreciate.”
xpswmm Version 10 users now have the tools needed to predict the extent and duration of flooding while assessing the ability of technologies and management practices to mitigate flooding.
The software provides an environment for building 2D models that simulate urban stormwater, sanitary sewers, river flooding and pollutant transport. Additional enhancements include a layer control panel, enhanced XP Tables capabilities, DTM integration and expanded BMP capabilities.
Fully 2D models have been widely used for modeling river and coastal hydraulics and recently have become a viable practical option for modeling urban floods. As a stormwater management tool, 2D models are more accurate and produce results that are more readily understood and accepted by managers, decision makers and other stakeholders.
Modeling Package
The 2D modeling package is based on the TUFLOW program developed in Australia by WBM Oceanics 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.
xpswmm has incorporated the TUFLOW engine into a graphical interface that steps the user through preprocessing of input data and the calculation of the model. All of software’s 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.
A feature of xpswmm with 2D is its ability to dynamically link to any 1D (quasi-2D) model in an integrated fashion. The user sets up the model as a combination of 1D network domains linked to 2D domains as a single model.
