5. Implementation for generating river deltas

The contribution of this work within the area of procedural terrain generation is to provide a new method that generates river deltas. Likewise, this is a new adaptation of the L-systems. In this section rules and guidelines are provided to adapt the grammar and the graphic interpretation to achieve the generation of river delta skeletons.

L-systems are a form of chaotic systems [15]; in practice, this means that a small change in the initial conditions, the axiom or the rules, will have an important impact on the results. These changes are hard to predict and control. For this reason, the experimentations to obtain different systems that produced branching rivers where performed in an empirical way; nevertheless, there are certain observations that were taken from [7]:


There are other guidelines specific for river deltas:
