1. Build a simple model of water dynamics using the systems dynamics modeler. Assume a flow-rate in and a flow-rate out. Compare how changing the flow rates affect the level of the water.
2. Open the Tabonuco-Yagrumo Hybrid model in the System Dynamics section of the NetLogo models library. Currently, the growth of new trees is random. Modify the code so it is spatially correlated. Also, modify the hurricane code so that trees that are removed are spatially correlated. Add a human agent that removes trees in a plot. How do all these changes affect the stability of the system?
