This document proposes a deterministic cellular automata model to simulate a sloped sandpile. The model allows for a slope along one axis and uses formulas derived from regression analysis to determine how sand is distributed to neighboring tiles. Increasing the slope seems to introduce more instability in the form of vertical walls that build up. These walls tend to break laterally, dispersing low heights of sand horizontally. While the model performs as expected in basic cases, it has some limitations in realistically simulating movement of sand up a slope and containing larger spikes at high slopes. Further work is needed to improve the model.
