Understanding the ICM simulation engine

Describe how ICM works with 1D and 2D hydraulic simulation engines.


InfoWorks ICM is both a geospatial user interface and a hydraulic simulation engine. You work in the geospatial user interface to build models. The simulation engine uses complex hydraulic calculations to generate simulation outputs.

1D model simulations use the St. Venant equations, which govern the conservation of mass and momentum. The conveyance function is based on either the Colebrook-White or Manning expressions.

A real-time control component (RTC) allows you to control regulators during the simulation.
