ICM SWMM Subcatchment Variable Names for SQL and Ruby Scripts

     The file "opwrowobjectlayoutswmm.xml" is a data file used by the Integrated Urban Water Management Model (ICM) software. The ICM software is used toVV simulate and analyze the performance of stormwater management systems, including the design and operation of stormwater collection and conveyance systems.

The file "opwrowobjectlayoutswmm.xml" contains variable names specific to the SWMM (Storm Water Management Model) conduit feature in the ICM software. These variable names are used in SQL and Ruby scripts, which are programming languages used to manipulate and analyze the data generated by the ICM software.

These variable names are used to represent the different attributes of a Subcatchment within the ICM software and the SQL and Ruby scripts allow users to access and manipulate that data in a variety of ways.
