Scripting

In CWMS, scripts provide a way to automate the program for the purpose of executing a prescribed set of actions with a simple trigger. Scripting simplifies user operation, ensures repeatability and consistency of results, reduces time required to generate results, and permits schedules of an operation in the future.

CWMS uses the Jython scripting language. Jython is a special implementation of the Python scripting language that is able to interact with programs written in Java.

Some uses of scripting in CWMS: 

• Running an existing forecast with one or more alternatives with a single button click (replacing many mouse clicks with one).
• Creating a new forecast based on the current time, and running it with one or more alternatives.
• Scheduling an action such as creating a new forecast to happen sometime in the future (possibly on a recurring basis).
• Working with a mixture of HEC-DSS and the CWMS database.
