Manually getting a large number of rainfalls into XPSWMM can take quite some time. In this article we will show the step by step instruction on using the XPX exchange format to import rainfall data.
Major steps are,
Start with a new model and add the rainfall into the global data.

Many Cities around the United States have access to freely available high resolution radar rainfall data. In this article, we’ll have a step by step example on downloading a few months worth of radar rainfall data and see them playing in ICM.
ICM supports the DPR product (Instantaneous Precipitation Rate), the first thing is to find the nearest station with that data. Use the map below, we can see all the NEXRAD stations.

In part 1 we imported rainfall into a TSDB from an existing rainfall event file. In part 2, we will create rainfall in TSDB from scratches.
A great way for new users to learn how TSDB works is to import from an existing model (see part 1), and then study how the import tool sets up the TVD connectors.
In this example, we will recreate the model in part 1 by connecting to a csv file.
First, let’s copy the rainfall…

ICM provides a wide range of tools to style an inundation map and it could be overwhelming for new users. In this article, we will go through a few typical setup.
ICM offers two ways to render flooding extent.

TSDB (time series database) provides a streamlined workflow for getting real-time data into ICM models. It can greatly reduce the time needed to run a model with real-time data from external sources by automating the data connection, retrieval, conversion and validation.
In this article we’ll focus on the commonly used methods to connect rainfall sources to ICM. We will cover the following 3 scenarios,
As shown below, we have an existing model using a rainfall event. …

When modeling storage, entering a depth storage curve seems to be the only option in XPSWMM. What if you need to enter a depth-volume curve instead?
Designed for advanced users, we can overwrite default behavior of the XPSWMM using configuration keywords.

ICM assumes a manhole has two part, a shaft and a chamber.
The default values works fine for most manholes, just set the “#D flag” for the input parameters, ICM will calculate the parameters for you.

For an ICM 2D model that takes hours or even days to run, it could greatly impact the schedule of a project. In this article, we’ll discuss a few quick steps to identify areas for improvements.
Below are the common areas to look into,

XPSWMM has a few “secret” tools for advanced users who really need to look under the hood to see how the engine does its calculations. In this article, we’ll show a few tips for getting very detailed information about river reaches geometry, hydraulic characteristics, and simulation results.
1D log has lots of detailed information for each river reach in the model. You can find the geometry summary with length, max. areas.
In Table E15, you can find the water volume.

ICM TSDB provides a streamlined process for getting external monitoring, forecasting time series data into the ICM model. Once the external connection is setup, the retrieval of the data is automated. When ICM runs a model, it automatically pulls the needed input data from the sources. When the run completes, it automatically pulls the data for comparison/calibration. For utilities with permanent flow meters in ground, a TSDB enabled workflow can eliminate tedious data preparation work which can easily take hours to days for each model run. These efficiency gains will enable and empower the utility to…
