My Masters Project at University College London concentrated on recording and analysing the meander geometry of 'canali' on the surface of Venus. These venusian channels are particularly intriguing as they resemble river channels on Earth. Canali on Venus are thought unique on terrestrial planets because of their great lengths (up to 7300km) and near-constant widths. Due to liquid water being unstable at the surface of Venus in the current epoch, low-melting-point lavas that maintain near-constant viscosity for several thousand kilometres are considered to be the canali-forming agents.
Results of meander geometry measurements imply that the process of canali formation is unlike any known volcanic or aqueous process on other terrestrial bodies. Meander wavelengths indicate formation by a fluid of high discharge rate, and differences from other solar-system lava channel geometry suggest that this fluid was not necessarily volcanic in origin. Analysis of associated topographic data suggests that Canali were forming before and during the early stages of plains tectonism.
