Thermal erosion resulting from ground thawing produced by heat transfer from water flow to the frozen ground could explain Martian outflow channel morphology. A 1D model was used to estimate the thermal erosion efficiency. The model was tested by comparing its results with measurements conducted on Siberian rivers and in experiments using a hydraulic channel. The results show that even a small value of Delta T = 5 K (temperature of the water minus temperature of the ground surface) produces active thermal erosion. Measurement with various ground ice samples, discharge rates, and temperatures are proposed.
