Parametric tools allow designers to set formal parameters or logics for design objects (in this case berms and spoils piles) and rapidly compute many iterations at once. In this project, we use the parameters of damba construction and spoils piling to create a tool to model and visualize dambas and spoils piles in various configurations. 

​

In this project, the boundaries of the proposed berm system are the edges of the intact forest and the main channel of the river at the start of the project. These edges are subdivided into start and end points for the berm and distances between all possible start and end points are calculated. Each of these possible berms is then recalculated as a set of bi-arcs, or curves composed of two simple arcs. Because these arcs face opposite directions with respect to the path of the sun, each face of the berm creates a different gradient of exposure to the sun.
