ELM Dynamic Equations



The ELM dynamic equations have been parsed from the source code (C) files into a pseudo-code format, removing significant amounts of C syntax, and removing code (control, debug code etc.) that does not affect the dynamic calculations.  
The pseudo code shows the equations and comments as they are found in the source code files (sans much of the language syntax), and provides a brief functional description that parallels the segments of code. ELM dynamic equations are considered here in the context of their spatial functionality.  

  • Function sequencing - shows the basic program flow control.
  • Vertical solutions - shows the vertical dynamics within the "unit" model.
  • Horizontal raster solutions - shows the horizontal flow dynamics among grid cells.
  • Canal network solutions - shows the horizontal flow dyamics among the canal/levee vectors, raster grid cells, and point water control structures.
 
The manuscript on (OLD code version!) ELM v1.0 (OLD code version!) provides detailed documention of most of the dynamic equations, though significant revisions have been made to portions of the model since that version. However, it is still a useful description of the general methods and performance of the ELM dynamics.
