GIS Application | Hilkka Kallio | 2005-07-29
To calculate the mean sea level rise during the 21st century both land uplift and sea level results of the Regional Climate Model (RCM) were calculated relative to the geoid. The geoid describes the equipotential surface of the Earths gravity field which coincides the mean sea surface. The same surface would arise if the sea water would freely intrude under the continents for example through a tunnel network...
GIS-application in Itä-Uusimaa Case Study Area | Hilkka Kallio | 2005-08-01
This research employed spatial analysis tools in Geographic Information System (GIS) to evaluate the spatial extent of future flood prone areas in the two case study Cities Porvoo and Loviisa. A sum operation was run in the raster calculator to generate a flood prone area analysis with digital elevation model (DEM) and sea level results of the Regional Climate Model (RCM) as source data. ..
Land Uplift & Subsidence | Hilkka Kallio | 2005-08-01
n the long term perspectives the sea surface is subject to constant changes. Its variability depends on a combination of global, regional and local factors and also time scale. Climate change has been one of the main causes of changes in quantity of oceanic water during the history of the Earth. During the last glaciation enormous fresh-water masses were stored in ice sheets in northern Europe and northern America...
