Abstract
One of the natural threats that arises as a result of temporary surface runoff is flooding, which has a large amount of solid material, a high level of water in the streams, a sudden appearance, and a rapid flow velocity. The Wadi Amlog Basin is characterized by the lack of rain and the prevalence of drought, but it is exposed to sudden rains that lead to surface runoff in its dry valleys in a way that results in threats to infrastructure and spatial development in the coastal region. Within this framework, the purpose of this research is to investigate the possible areas of flood hazard by using GIS techniques based on morphometric assessment parameters to determine the risk level of specified subbasins from a digital elevation model (DEM) using remotely sensed SRTM images. The case study results utilized five evaluation degrees, very low, low, moderate, high, and very high, to interpret the flood danger, in a way that contributes to protecting the places most affected by the dangers of floods in the subbasins in the study area.
期刊介绍:
Applied Geomatics (AGMJ) is the official journal of SIFET the Italian Society of Photogrammetry and Topography and covers all aspects and information on scientific and technical advances in the geomatics sciences. The Journal publishes innovative contributions in geomatics applications ranging from the integration of instruments, methodologies and technologies and their use in the environmental sciences, engineering and other natural sciences.
The areas of interest include many research fields such as: remote sensing, close range and videometric photogrammetry, image analysis, digital mapping, land and geographic information systems, geographic information science, integrated geodesy, spatial data analysis, heritage recording; network adjustment and numerical processes. Furthermore, Applied Geomatics is open to articles from all areas of deformation measurements and analysis, structural engineering, mechanical engineering and all trends in earth and planetary survey science and space technology. The Journal also contains notices of conferences and international workshops, industry news, and information on new products. It provides a useful forum for professional and academic scientists involved in geomatics science and technology.
