The city of Mississauga has recently identified strategic growth areas where investments will be targeted for redevelopment and intensification projects. One of the growth areas has a history of flooding during major storm events. In order to redevelop this area, businesses and land owners need to prepare development proposals ensuring that appropriate flood proofing requirements have been achi...

Earth Observation is a powerful tool for the detection of floods. Microwave sensors are typically favored as they deliver data enabling water detection independent of solar illumination or cloud cover conditions. However, scale issues play an important role in radar based flood mapping. Depending on the flood related phenomenon under investigation, some sensors might be more suitable than other...

The present study introduces a multi-criteria index to assess flood hazard areas in a regional scale. Accordingly, a Flood Hazard Index (FHI) has been defined and a spatial analysis in a GIS environment has been applied for the estimation of its value. The developed methodology processes information of seven parameters namely flow accumulation, distance from the drainage network, elevation, lan...

New methods allow the direct computation of flood inundation maps from lidar data, independently discharge estimates, hydraulic analysis, or defined cross sections. One method projects interpolated profile measured levels onto surrounding topography, creating a smooth surface that is entirely based on data and geometrical relationships. A second computes for any simple function relates water to...

Floods are one of the most common hazards in the world, affect ing people’s lives and livelihoods. Flood hazard mapping and flood shelters suitability analysis are v ital elements in appropriate land use planning for flood-prone areas. This paper describes application of Remote Sensing (RS) and Geographical Information Systems (GIS) in identifying flood hazard zones and flood shelters and are t...

Environmental monitoring is the most popular application of wireless sensor networks (WSNs). At present, WSNs have been used for a number of applications such as soil moisture monitoring, solar radiation mapping, aquatic monitoring, glacial control and climate change, and forest fire alarm. The ability to place autonomous and low cost nodes in large harsh environments without communication infr...

Assessing and mapping damage risk of floods for large river basins is still in its infancy. Damage risk is understood to be the combination of flood hazard and the vulnerability of communities to a flood of a particular return period. Risk is calculated and mapped for two communities in which dykes are not located for flood protection: Meissen on the Elbe River and Döbeln in the Mulde catchment...

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 the patients for anterior and ...
