Both XPSWMM and XPStorm are complete software packages for modeling stormwater and wastewater flows and pollutants. XPSWMM and XPStorm are used by scientists, engineers, and resource and asset managers to simulate natural rainfall-runoff processes and the performance of engineered systems that manage water resources. The application is used to develop link-node and spatially distributed models that are used for the analysis, design, and simulation of storm and wastewater systems. The application also models flow and pollutant transport in natural systems including rivers, lakes, and floodplains with groundwater interaction. Floodplain flow can be modeled in 2 dimensions or in an integrated 1D-2D linked configuration.
This Getting Started tutorial contains 17 self-guided tutorials that demonstrate basic tasks required to build and solve numerical models and analyze simulation results. A list of data files required to start each tutorial is presented at the beginning of each tutorial. The associated tutorial files can be downloaded from the Resource Downloads page.
The tutorials are intended to be run on the latest release of the software with each tutorial demonstrating a defined skill set. The tutorials are self contained and may be followed in any order. The required skill level is listed at the beginning of each tutorial. User skill levels are defined as:
Suggested knowledge and skills
The purpose of these tutorials is to demonstrate the software features and the typical workflow for common applications. It is not our intention that the values used in these tutorials represent typical values that you would extract for your own modeling needs. You must make all the engineering judgments on parameter values.
The models in this guide utilize either US Customary or SI units. We have a worldwide customer base and our users work in both measurement systems. It is not recommended that you convert or mix units within a model. However, as described in Tutorial 12, the results and model data can be presented with different units by formatting the field. A table on the following page provides a conversion of typical units used within the program.
US Customary and SI Units and Conversions used in XPSWMM and XPStorm Models
US Customary Units
Length, width, depth, elevation, stage
Precipitation, infiltration depth
