WHAT IS IT?

This model accuratly estimates the cost of running certain preservation efforts to save the depleading delta smelt. This interactive model can accuratly show the costs to these efforts.

HOW IT WORKS

Clicking "setup" gets the model ready while adjusting the sliders activates global variables, which are shown on the plots via mathematical equations.

HOW TO USE IT

SETUP-Starts the model SLIDERS-Used to adjust amounts of exspenses START-Starts the model and/or adds one month to the model IMPUT BOX-Type in the desired budget

THINGS TO NOTICE

Notice how the speech bubbles are created and what other features you could create using this formula.

THINGS TO TRY

Somthing to try is to adjust the costs for the certain expenses.

EXTENDING THE MODEL

Eventually it would be great if there were more sliders representing more expenses. It would also be better to make the default screen more interactive.

NETLOGO FEATURES

Some great and unique features of NetLogo used in this model are the label feature and the turtle editor.
