Abstract
The goal of the project was to spatially represent human created structures in the floodplain to be utilized by Halton Conservation and Halton Emergency Services during natural hazard events. The project was undertaken by Emily Araujo and Magdalena Kula for Conservation Halton in conjunction with Niagara College from October 2009 to June 2010. Flood related risks not only impact human life and property, but also effect the natural environment. Flooding hazards can occur when a major storm event releases more precipitation than the river channels can sustain. Flooding is also a factor of soil infiltration and human-made structures built in the floodplain that can limit infiltration. This study created a tracking system with a geodatabase and the latest 2009 air photo imagery of the Halton watersheds to determine where potential urban hazard zones exist during hazard events. The 2009 air photos were complied into a raster catalogue for faster interpretation of the structures. The floodplain boundaries were provided by Conservation Halton and were used with a five kilometre grid system track the interpretation progress. The structures were classified into 11 built structure types. The study found that residential and roadway classes were the most commonly built structures in the floodplain and that areas in the floodplain are being impacted by urban development and encroachment.
