Flood is one of the most destructive natural hazards which impose vast costs in order to compensate its effects, especially in areas where there are manifestations of human development (such as cities). Urban development, particularly in the margins of rivers, has increased flood damages in recent decades. The aim of this study was to develop flood hazard maps of Birjand plain based on analyses...

Generation of flood inundation maps is beneficial in risk assessment and evaluation. Flood mapping can be achieved by many remote sensing techniques like change detection (CD) with thresholding machine learning-based (ML) methods. Optical synthetic aperture radar (SAR) imagery are widely used, provided different satellite systems. This study used Sentinel-1 SAR Sentinel-2 MSI data Google Earth ...

As part of the contribution to flood disaster risk reduction, it is important to identify and characterize flood areas, locations, and durations. Multiple satellite-based flood mapping and monitoring are an imperative process and the fundamental part of risk assessment in disaster risk management. In this paper, the MODIS-derived synchronized floodwater index (SfWi) was used to detect the maxim...

  Introduction: In the current study, we evaluated the feasibility of body outlining using Tc-99m filled flood source for lymphoscintigraphy imaging. Methods: 80 patients were included in the study. Sentinel node mapping was done using Tc-99m Antimony sulfide colloid. For outlining the body a Tc-99m filled flood source was used which was placed behind or lateral to t...

Flash floods are considered to be one the worst kind of hazard. They are characterized by their suddenness, rarity, small scale, heavy rain and peak discharge, unpredictable, fast and violent movement. It has severe effects on human society in the form life losses, damages to property, roads, communication and on natural settings. Advances in hydrology, meteorology, engineering, using of GIS an...

Conventionally flood mapping typically includes only a static water level (e.g. peak of a storm tide) in coastal flood inundation events. Additional factors become increasingly important when increased water-level thresholds are met during the combination of a storm tide and increased mean sea level. This research incorporates factors such as wave overtopping and river flow in a range of flood ...

Flood is one of the most devastating natural hazards which lead to the loss of lives, properties and resources. It has therefore become important to create easily read, rapidly accessible flood hazard map, which will prioritize the mitigation effects. This study addresses the need for an efficient and cost-effective methodology for preparing flood hazard maps in Ghana, particularly those region...
