In orbit since 2006 NASA’s Mars Reconnaissance Orbiter has totally changed the way we study the geomorphology of Mars. Aboard is the High Resolution Science Imaging Experiment (HiRISE) which takes images at 25 cm/pixel, an equivalent quantity to satellite imaging of the Earth. This allows reconstruction of the surface topography at 1 m/pixel by stereophotogrammetry, allowing in detail morphological studies of Mars’ surface. In this presentation I will show topographic long profiles of Martian gullies and sand dunes and how we have used these to infer the processes shaping Mars today and in the last few million years.
15:15-15:35
Gully erosion is a significant geomorphic process triggered by both natural and human-induced factors, leading to multiple environmental and socio-economic consequences, particularly in developing and dryland regions. The presentation introduces various drivers, and management measures of gullies, based on case studies conducted in various environmental settings across Ethiopia from 2014 to 2023.
15:35-15:55
The sediment transport mode often determines the longitudinal gradient of a landform. This will be explained through the laws observed in the longitudinal gradient of landforms and examples of abrupt changes in the longitudinal gradient at Daisen Volcano, Tottori, Japan and so on.
