Water has supposedly marked the surface of Mars and produced characteristic landforms. To understand the history of water on Mars, we take a close look at key locations with the High-Resolution Imaging Science Experiment on board the Mars Reconnaissance Orbiter, reaching fine spatial scales of 25 to 32 centimeters per pixel. Boulders ranging up to approximately 2 meters in diameter are ubiquito...

1 Motivation The New Orleans area levee failures during Hurricane Katrina drew media attention to an important problem in Civil Engineering. The emphasis of our work is on earthen levees, dams, and embankments. A major cause of failures of such structures is overtopping, which causes erosion to the point of breaching the crest. Our research focuses on simulating the initial small-scale features...

Digital mapping was applied for a key site located at the Southern Cis-Ural region near Ufa city (the Republic of Bashkortostan, Russia). The digital soil map (DSM) created using open-source GIS software packages and compared to conventional (CSM) one. As input parameters, we used standard morphometric values topography field descriptions soils, including authors’ data. DSM same scale (1:25,000...

Streaks and gullies (Figs 1,2) are common on Martian slopes, and are geologically young; slope streaks have formed during the last few years of Mars Global Surveyor imaging. Both slope streaks [1] and gullies [2] involve flow of granular material, but it is not clear whether liquid water (or another suspending agent) was involved. The possibility that liquid water was involved makes gullies and...

Water erosion is one of the main forms soil degradation, causing economic, environmental, and social damage. This study evaluated effects different formation stages gullies (initial - IG; juvenile- JG; mature MG; senile SG) on chemical, organic carbon microbiological attributes soil, using a secondary forest (SF) two areas pasture as references in “Mar de Morros” environment Brazilian Atlantic ...
