It is used by scientists, engineers and managers to develop link-node (1D) and spatially distributed hydraulic models (2D) for analysis and design. Its use over the last 25 years has made it one of the most stable and well-used simulation software programs in the world.
xpswmm simulates natural rainfall-runoff processes and the hydraulic performance of drainage systems used to manage our water resources. It allows integrated analysis of flow and pollutant transport in engineered and natural systems including ponds, rivers, lakes, overland floodplains and the interaction with groundwater.
Use xpswmm for fully integrated hydrologic and hydraulic modeling – simulate the whole water cycle in one system! This comprehensive software will allow you to model with confidence.
Holistic Modeling. Hydrology, Hydraulics and Water Quality. Experts know that a change to one element in a system may affect the performance of the entire system. xpswmm allows you to perform fully integrated system modeling — channels, pipes, streets, control structures, ponds, weirs, pumps, catchments, groundwater table, overland floodplains, rain gardens, infiltration trenches and more.
Model the Real World. You need a tool with model elements that accurately reflect the physical realities of your drainage system. The number of available element types, shapes and control parameters are unparalleled in free or competing proprietary software packages. Minimise the need for approximations and "modeling tricks" by using xpswmm.
Regulatory Approval. Widely used and accepted in private practice, it is also EPA tested and FEMA approved. Countless regulatory organisations are familiar with xpswmm and prefer modeling performed with its powerful tools.
Localisation. xpswmm has been customised and localised for many niche markets around the world. Specific hydrologic methods, specialised hydraulic routines and purpose-build outpot templates will help you model according to local standards.
