This model provides a visual demonstration of the topography of a landscape. It can sometimes be
difficult to represent heights and slopes on a 2-dimensional computer screen, so mapmakers use
indicators to show the average height of each "square" of terrain. These indicators are usually
color-coded to make it more obvious to viewers where the peaks and valleys are.
What are the elements of this Model?
This model simulates placing a random sprinkling of "bunnies" on a hilly landscape. As would be
expected, once the model starts the bunnies will roll downhill, eventually congregating at one or
more of the lowest points.
How do I use this Model?
To begin, it is recommended that you set the speed to "slower"; otherwise, the bunnies may move
more quickly than you can track. As the model runs, you can choose how many rabbits on the field,
as well as the smoothness. Higher smoothness values tend to lead to fewer, larger peaks and
valleys, while lower smoothness values lead to more broken terrain.
What should I expect?
The rabbits should all quickly congregate at the lowest point(s) on the map. In general, more
smooth terrain leads to fewer points of conglomeration (because all of the terrain is sloping down
to those points) while rougher terrain leads to numerous, smaller clumps of rabbits.
