Introduction

• RHESSys is a spatially distributed model of
  watershed carbon, water and nutrient dynamics.
• RHESSys stands for Regional HydroEcological
  Simulation System.

Project Goals

• Conversion of the clients C code into an object
  oriented code in C
• GUI for assembling the necessary input data,
  carrying out preprocessing and model
  parameterization and (if possible) output
  visualization.

4
Successes

• Timely completion of the C to C conversion.
• Completion of the GUI

5
Model

• Time step model (1 hr increments)
• Event driven
• Multiple level
• Multiple variables

GUI

• Implemented with Java Swing/JFC
• Main function gather user input and construct
  command line
• To be implemented Visualization

GUI/Model Communication

• The model is started in the Java code with a
  simple exec call of the C program.
• Communication from this point occurs through the
  standard error and standard output streams.

11
GUI/Model Communication
At this point, the model arbitrarily uses either
stream to display the progress of the model, and
output significant events.

Where to go from here?

• Despite our hard work, there are still problems
  to solve
• General Clean-up
• Converting v5 to an OO structure
• Output visualization
• Implementing the climate as a DLL
