Asseeement of the vulnerability degree of different lithological formations in the
catchment area of Agia Eirini Gorge, western Crete
(EN)
This paper presents a methodology for assessing the degree of vulnerability of different lithology
formations constituting the drainage basin of the gorge of Agia Eirini. The methodology is
based on the processing of spatial aspects parameters of lithology, hydrography, geomorphology
and the vegetation cover, which are related with the weathering impact on formations either
directly or indirectly.
Initially a series of primary spatial data on geology, topography, the river network and the
land use in the region, were used to produce thematic maps. These maps include the geological
map, the digital terrain model (DTM), the map of the land use, and hydrographic maps of
density and frequency. By processing the data according to their role in enhancing the vulnerability
of formations, the data were determined and the following thematic maps: “Map of geological
formations susceptible to weathering”, “Map of hydrographic texture”, “Map of
morphological inclinations” and “land use map protecting against the loss of disintegrated
material were produced. By appropriate combination of these secondary data, areas of vulnerability
of formations were recorded which are shown on a final thematic map. This information
is particularly valuable in the management planning and gives the opportunity to
evaluate and predict the impact of various proposed projects or future scenarios. They can also
be used to identify positions to take necessary measures to protect areas at high risk of loss of
material.
