Supplier: XP Software

xpstorm is a comprehensive software package for dynamic modeling of urban stormwater systems and river systems.


It is used by scientists, engineers and managers to develop link-node (1D) and spatially distributed (2D) hydraulic models for analysis and design. Widely used by private consultants and public agencies responsible for stormwater and flooding regulation, xpstorm is one of the most stable and well-accepted modeling and design packages in the world.

xpstorm simulates natural rainfall-runoff processes and the hydraulic performance of drainage systems and floodplains. It allows integrated analysis of flow in engineered and natural systems including ponds, rivers, lakes, overland floodplains and interaction with groundwater.

Use xpstorm for fully integrated hydrologic and hydraulic stormwater modeling – from cloud to ocean! This comprehensive software will allow you to Model With Confidence.

Why xpstorm?

Integrated Stormwater Modeling. Comprehensive hydrology and hydraulics in the same model.  Don’t jump between two or three different stormwater packages to build a complete stormwater model. xpstorm offers the tools to perform fully integrated system modeling — channels, pipes, streets, inlets, ponds, weirs, pumps, catchments, groundwater table, overland floodplains, rain gardens, infiltration trenches and more.

Model the Real World. You need a model that accurately reflects the physical realities of your drainage system.  Fully linked 1D and 2D modeling allows you to see the true behavior of stormwater flow in natural and engineered systems. Minimise the need for approximations and “modeling tricks” by using xpstorm!

Advanced Design. Automatically identify flow choke points and let xpstorm design solutions (pipe sizes, slopes). Use automated Detention Pond Optimisation methods to configure storage. Fully dynamic hydraulic analysis will allow you to complete LID/WSUD design to maximise benefits at lower costs.

Localisation. Your hydrology, your way.  With over 15 hydrologic methods available and numerous ways to input real or synthetic rainfall data, xpstorm allows you to model the appropriate rainfall/runoff for your project.
