xpswmm is the only economical hydrodynamic software package that provides all the major hydrology methods to allow you to estimate your stormwater inflows, wastewater, dry weather and infiltration flows.
Design and analysis of stormwater projects including piped and channel flows. xpstorm provides a far more intuitive stormwater design program aimed at everyday stormwater design analysis and planning requirements.
xp2D is a fully dynamic FEMA-approved 2D flow module for xpswmm or xpstorm. It provides an incredibly accurate tool to predict the extent, depth, velocity and duration of flooding to evaluate flood mitigation technologies and management practices.
xprafts will revolutionize your urban and rural storm water drainage practise by accurately analyzing rainfall and runoff in any land use area (available through Australia only).
Design, size and analyze new or existing culverts under steady or dynamic flows. xpculvert is the first and only combined culvert and pond analyzer to use the full unsteady flow equations in conjunction with the US-FHWA inlet rating equation.
Water Surface Pressure Gradient (WSPG) is a hydraulic analysis model that computes and plots uniform and non-uniform steady flow water surface profiles and pressure gradients. The Los Angeles County Department of Public Works (LADPW) requires use of this model for hydraulic design.
Designed by engineers for engineers, WinDes® uses proven and universally adopted methodologies to design and analyse drainage systems, including a powerful flow simulation module, and a comprehensive costing and quantities package.
xpsite3D is an intelligent design package for sitework, roads and highways. It provides full control of very rapid 3D views of all aspects of your designs – above and below ground.
xpdrainage is a sustainable drainage design package for use by landscape architects and civil engineers. Combine LID, WSUD and SuDS with traditional drainage and test the whole design for flow and pollution control.
