Assessment of morphometric parameters of Greek Rhone-type deltas. Hydrogeologic and environmental aspects

 The morphometric characteristics and some features concerning the local conditions of three Rhone-type Greek deltas are considered, summarized and correlated. They both express the deltaic internal lithologic structure and the configuration of the coast lines and subaqueous profiles. Despite the existing differences, concerning the lithologic structure, the coastline shape and the subaqueous profile, the Rhone type deltas maintain their principal characters and their basic configuration of the deltaic prominence. The above-mentioned differences are mainly due to local conditions which, as epigenetic factors, affect the distribution of transported material and complete the classification and deposit action of marine mechanisms, mainly the wave action and sea currents. The totality of these factors determined the continental and subaqueous structure of the deltas, which is related to the environmental and hydrogeological aspects presented in this paper.
