[1] We show evidence of very recent ( 25–40 Myr) geologic activity on the eastern flank of Olympus Mons volcano that includes a suite of fluvial (channel networks), volcanic (emplacement of lava flows and dikes), and tectonic (wrinkle ridges and troughs) processes. The combination and youth of these features confirms the importance of geological activity continuing to the present on Mars. Citat...

During construction of a dike, slope stability often reaches critical levels, due to the excess pore water pressures in foundation. The loading condition during has similarities with design conditions flood loading. Not only terms as main driving force, but also criticality stability. This paper examines how information survival stage can be used improve reliability estimate for dike conditions...

Abstract The contemporary occurrence of juvenile gas emissions at springs or mofettes in active volcanic areas can be observed worldwide. This correlation is less frequent with dormant post-volcanic activity. NW-Bohemia/Vogtland region located the Eger rift zone (Czech Republic) provides an intriguing example this between numerous Neogene-aged post-volcanism locations and fluid emission sites. ...

For the risk assessment of flood defense, a comprehensive understanding factors affecting dike failure is essential. Traditional methods are mostly based on experts’ experience and focus just one type mode defensive structures. The resources, including analytical non-analytical factors, were summarized firstly according to general dikes. uncertainty resources that affect safety can be quantifie...

Sea level rise, land subsidence and population growth lead to steadily increasing flood risks in low-lying coastal areas. Hard defense structures such as dikes dams should be regularly heightened strengthened sustain their protective function. Further, hard can induce negative effects on the surrounding ecosystem. Therefore, nature-based approaches risk reduction are increasingly promoted. Vege...
