Abstract

We present quantitive geomorphic analyses of high resolution digital elevation models (DEMs) of four gully systems on Mars. We first tested our methods in different gully systems on Earth, to verify that we can use slope-area analysis to discriminate between dry mass wasting, debris flow (involving water) and pure water flow. We then applied the analyses to Mars, where our results indicate that debris flow is the dominant gully-forming process.
