In recent decades, extreme storm events due to climate change have frequently occurred worldwide, a few of which even consecutively; we class such rainfall as mega events. That is say, if the inter-arrival time between with 100-year frequency less than IETD (Inter-Event Time Definition), event can be considered event. Therefore, aim this study was implement flood inundation analysis using hypot...

Flood is one of the natural hazards that have negative impacts on peoples and property. It occurs in lowland areas without any sign when excessive rains fall adjacent highland areas. Since flood unavoidable phenomena, adopting protective mechanisms are crucial. This study was conducted Jigjiga town, Eastern Ethiopia with main objective delineating risk For purpose mapping preparation, hydrology...

Objectives- A flood is a strangely high stage in river generally, the level at which overflows its banks inundates adjacent area. Flood occurs due to intense rainfall, dense population, industrialization, illegal settlement along riverbanks, bank erosion, tide, and urbanization, it causes harmful damage human beings properties. It can be taken care of by adopting risk measures. One measures dev...

Rivers are important water resources for human life, but sometimes cause irreparable damages. The flood plains are fertile terrains which are endangered by flood. Flood hazard mapping is one of the basic methods in flood fighting. In order to decline flood damages, the simulation of the hydraulic behavior of the rivers during flood occurrence is very important. In this study, areas that are flo...

Due to the immense damage caused by dam failure, especially dams constructed near large cities, it is necessary to consider the breaking phenomena as well as studying and designing different parts of the dam. For this purpose, the hydrograph of the outflow due to dam failure must be identified according to size of the fracture and then flood routing, and flood zone must be determined based on t...
