Χάρτες Διάβρωσης με Χρήση Δορυφορικών Δεδομένων και του Μοντέλου RUSLE στην Πάρνηθα μετά την Πυρκαγιά του 2007
Summary:
The geomorphological and hydrological effects of the wildfireshave as result a
serious increase on soil erosion at the fire-devastated
environments.Nevertheless the influence of the wildfires to soil erosion /
sediment transport and their impact to the erosional and depositional
environment and equilibrium and eventually to the longer-term geological
framework is often neglected. In comparison to traditional methods, such as
field inventories, remote sensing provides a cost-effective and rapid option in
mapping the spatial and temporal variability of wildfires.
In this study, is examined whether the absence of vegetation due to the
wildfires, in composition with the changes in the soil characteristically
propertiesare indeed the main triggering mechanisms for high erosional rates
and is tried the quantification of these parameters in a comprehensive model.
In particular, the objective of the present study has been to assess the
changes in soil erosion risk in Mediterranean setting as a result of a
wildfire, using remote sensing and Geographical Information Systems (GIS). Our
study region site comprises of the area of Mt. Parnitha, located approximately
30 km northwards the city of Athens, Greece. Mt. Parnitha experienced severe
wildfire from a wildfire on June 28th, 2007, suppressed 5 days later (July 1st,
2007).
