Abstract

Geomatic Engineering

climate change

spatial hydrology

catchment-based approaches

rainfall-related hazards

Landscape systems across the world have been altered dramatically to support modern economies, and there is strong evidence suggesting that most of the warming observed over the last fifty years is attributable to these activities. This, together with other associated climate-change events such as extreme weather conditions and rising sea levels, (which has increased through the twentieth century), are already affecting sensitive ecoregions across the globe. The archives of spatial information coupled with open-source software tools provide diverse ways to analyse and visualise scenarios of deleterious effects of climate change at a much finer scale. This study presents the framework of an ongoing project that utilises a combination of commercial and open-source geospatial data analysis software to identify areas with higher vulnerability by investigating existing spatial data. The datasets investigated in the study include catchment based characteristics derived from a spatial hydrology model using a high resolution hydrologically correct digital elevation model (DEM), land use, and empirical datasets on hazards related to flash flooding. The paper discusses how the integration of spatial and statistical techniques along with spatial hydrological models enable derivation of indices that can provide insight into a catchment's response to surface hydrology during heavy rainfall events.
