Flood hazard mapping in an urban area using combined hydrologic-hydraulic models and geospatial technologies

Environmental sensitivity of flash flood hazard using geospatial techniques

Flash flood has been increasing in the Khartoum area, Sudan due to geographical conditions and climatic change as heavy rainfall and high temperature, therefore the present work tried to estimate the sensitivity of flash flood. The present work proposes an advanced technique of flood sensitivity mapping using the method of analytical hierarchy process. Ten factors as elevation, slope, distance ...

Combining Satellite and Geospatial Technologies for Rainstorms Hazard Soft Mapping

Multiple Damaging Hydrological Events are rapidly developing into worldwide disasters with effects to the viable habitat for humankind and ecosystems. This research describes how data assimilation friendly models combining remotely sensed and ground hydrological data could be used for developing a soft geovisual communication in order to reduce the uncertainty in rainstorm hazard mapping. For t...

Seismic hazard zoning in Urmia urban area.

 Today, the resiliency of the human centers, especially urban centers against the natural hazards such as earthquakes, is one of the main challenges in the targeted management of urban. One of the effective strategies in the control, containment and prevention of risks from earthquakes is zoning of urban areas in terms of vulnerability. In this regard, the purpose of this study was to determine...

Flood Threat in an Area – Topical Natural Hazard

Based on last years experience we can say, that problem of flood threat in an area has already exceeded engineer-hydrological, respectively water economy frame. There are clear indicions, which indicate, that this phenomenon needs a complex view. It means particularly knowledge of run-off relations, which are connected with time and spacial wide spread of rainfalls, but also with land cover and...

Effect of digital elevation model’s resolution in producing flood hazard maps

Flooding is one of the most devastating natural disasters occurring annually in the Philippines. A call for a solution for this malady is very challenging as well as crucial to be addressed. Mapping flood hazard is an effective tool in determining the extent and depth of floods associated with hazard level in specified areas that need to be prioritized during flood occurrences. Precedent to the...
