Tropical Cyclones (TCs) in the Australian basin have relatively more erratic pathways than other parts of the world. About half the TCs generated in the basin make landfall, but the location of cyclogenesis appears to have a direct bearing on landfall outcome. As the human and economic toll of landfalling TCs are far more significant than the non-landfalling ones, this paper attempts to identify the distinguishing features that differentiate between the two and, develops a decision tree…

The high grade and low-grade metamorphic rocks with volcano sedimentary varieties and associated intrusions are the main characteristic geological formations of Eastern and south Eastern Ethiopia. The Mozambique and higher-grade metamorphic rock that dominated in the four parts of Ethiopia have limited exposure in the eastern Ethiopia. The Soka iron mineralization area was located in the Harerghe, Oromia Region, Eastern Ethiopia. Generally, the current study area is situated in the south…

The management of large-scale dam systems requires the integration of hydraulic control and downstream geotechnical stability. This study evaluates the emergency discharge operations at the Euphrates Dam during the May 2026 high-flow event, where discharge rates reached 800–1000 m³/s following reservoir storage levels exceeding 97%. Using the Manning equation for open channel flow and shear stress analysis (τ = γyS), this research assesses the hydraulic performance and the resulting erosion…
