Interconnected Channel and Pond Routing Model

Thank you for your interest in our flagship product, the ICPR Stormwater Modeling System.  ICPR has been in use for more than 25 years and was the first commercial program of its kind to successfully solve the problem of flood routing through complex networks of interconnected and hydraulically interdependent stormwater ponds.  The model has been expanded greatly since those early days and now includes hydrodynamic modeling of channel and pipe systems and a fully integrated hydrology component. 

The three primary building blocks in ICPR are Basins, Nodes and Links.  Stormwater runoff hydrographs are generated for basins and then assigned to nodes in the drainage network.  Nodes are used to represent ponds and specific locations in the drainage network such as along channels, streams, rivers, and junctions in pipe systems.  Stages are calculated at each of the nodes and links such as pipes, channel segments, weirs, and bridges are used to connect nodes together.  Flow rates are calculated for links based on stages at nodes.  

Examples of the Link-Node concept used in ICPR can be viewed by clicking on each of the thumbnails shown below.
