Recent Geomorphic Evolution of the Fan Delta of the Mornos River, Greece: Natural Processes and Human Impacts

XXXX, 2007 2007 Proceedings of the 11th International Congress, Athens, May, Πρακτικά 11ου Διεθνούς Συνεδρίου, Αθήνα, Μάιος 2007 2007 RECENT GEOMORPHIC EVOLUTION OF THE FAN DELTA OF THE MORNOS RIVER, GREECE: NATURAL PROCESSES AND HUMAN IMPACTS Karymbalis E., Gaki-Papanastassiou K.2, and Maroukian H.2 1 Harokopio University, Department of Geography, [email protected] National and Kapodistrian University of Athens, Faculty of Geology and Geoenvironment, Department of Geography and Climatology, [email protected], [email protected] Abstract The Mornos river fan delta is located on the northern side of the western Gulf of Corinth is a Gilbert-type fan delta with an arcuate form characterised by the abun dance of coarse sediments. In order to determine the processes which contributed in the configuration of the fan delta during the last two centuries a detailed geomor- phic map was prepared depicting both the deltaic plain and the coastal zone fea tures. Comparative examination of 1945, 1986 and 1998 aerial photographs and re liable maps of the last two centuries along with field observations detected recent changes of the fan delta. The construction of a dam in the upper reaches of the basin in 1980 has significantly decreased the sediment supply downstream and has slack ened the growth of the fan delta. After 1980 the eastern distributary has been aban doned causing a 120 m retreat at the river mouth. Although a progradation rate of 4 m/year has been observed for the western active distributary in the period between 1945 and 1986, no remarkable changes have occurred since that period. -

Low-lying coastal urban centers, populated deltas, and coastal protected areas are key societal hotspots of coastal vulnerability in terms of relative sea level change. Land deformation on a local scale can significantly affect estimations, so it is necessary to understand the rhythm and spatial distribution of potential land subsidence/uplift in coastal areas. The present study deals with the determination of the relative vertical rates of the land deformation and the sea-surface height by using multi-source Earth observation—synthetic aperture radar (SAR), global navigation satellite system (GNSS), tide gauge, and altimetry data. To this end, the multi-temporal SAR interferometry (MT-InSAR) technique was used in order to exploit the most recent Copernicus Sentinel-1 data. The products were set to a reference frame by using GNSS measurements and were combined with a re-analysis model assimilating satellite altimetry data, obtained by the Copernicus Marine Service. -
Birds of North Greece Holiday Report 2013
Birds of North Greece Holiday Report 2013 Greenwings Wildlife Holidays Tel: 01473 602389 Web: www.greenwings.co Email: [email protected] ©Greenwings 2013 Day 1: Monday 6th May Our late afternoon flight meant an evening drive from the airport to our base next to Lake Kerkini. During our journey we heard Nightingales every 50 metres and had first sightings of Hoopoe, Common Buzzard, Common Kestrel and Bee-eater. The Nightingales awaited us at our hotel too and with windows open at night, their melodic song could be heard in all directions. Once settled in we all took a very leisurely stroll to a taverna in the village square and discussed plans for the week ahead over a traditional and delicious mezedes style meal. Bird watching didn’t stop entirely for food and wine; Scops Owl was heard and White Storks were seen sitting on their telegraph pole top nests. All in all a good start to the holiday! Day 2: Tuesday 7th May After a good breakfast we drove to nearby Mandraki Harbour for our first proper view of Lake Kerkini. Steve and Hilary explained the lake’s importance to many birds, including the Dalmatian Pelicans seen fishing further out on the lake. We also learnt about the pressures facing the drowned forest due to changes in water levels in recent years and the associated impact this has had on various breeding bird species. Our view of it was distant and it wasn’t easy to appreciate the scale of it and the sheer richness of life it supports. Our boat trip planned for another day would bring us up close and personal though! The air was thick with buzzing insects chased by House Martins and Swallows and in the phragmites we could hear a Great Reed Warbler. -

A Remote Sensing Perspective
Δελτίο Ελληνικής Γεωλογικής Εταιρίας τομ. XLIV, 2011 54 Bulletin of the Geological Society of Greece vol. XLIV, 2011 Geomorphological and Environmental changes in West- ern Greece: a remote sensing perspective (1) (1) EMMANUEL VASSILAKIS & EFTHIMIA VERYKIOU - PAPASPYRIDAKOU ABSTRACT Several rapid geomorphological changes can be detected on the landscape of western Greece since the area is adjacent to the highly active Hellenic trench, where major geodynamic phenomena occur. At this part of the Hellenides, various active structures have been affecting the shallow layers of the overriding plate, due to tectonic movements and in some cases gypsum diapirism. Additionally, lots of environmental implications have been reported since a significant amount of development infrastructure is still being constructed in this area for more than the last twenty years, affecting the slower physical ongoing processes. The outcropping erodible lithologies of flysch in conjunction with the existence of high energy rivers reveal a rapidly evolving area with dynamic topography, which can be identified by using the appropriate methodologies. Remote sensing techniques prove to be the ideal way to locate changes at the physical geography of the studied area, especially when multi- temporal interpretation is implemented. In this paper we try to locate and analyze these changes by using medium resolution satellite images (Landsat TM and ETM+) of different temporal periods (1992, 2000 and 2005). After special interpretation of the acquired remote sensing images, which involves detailed co-registration and spectral analysis, the identified changes can be temporally cate- gorized between the three acquisition dates. The methodology requires the compilation of new sepa- rate datasets, one for each spectral channel from the three Landsat images, in order to detect chang- es in the absorption and reflection spectra for specific bandwidths. -

Moro, 1-00185, Roma, Italia. Received 12/1/88, in revised form 26/9/88, accepted 9/12/88. ABSTRACT With the use of 152 NOAA-6 and NOAA-7 satellite infrared images taken over the gulfs of Patras, Nafpaktos and Kqrinthos in Western Greece, a relatively complete description of sea surface temperature features and their evolution in time is obtained for these three marine basins. The satellite data, discussed in the light of recent theories on wind-induced marine upwellings near capes (Crépon and Richez, 1982 and Crépon et al., 1984), allow us to provide a general picture of wind-induced movements and upwellings.

RÉSUMÉ Remontées d'eau induites par le vent et courants dans les golfes de Patras, Nafpaktos et Corinthe, Grèce La structure thermique superficielle des golfes de Patras, Nafpaktos et Corinthe (Grèce) et son évolution sous l'effet du vent sont présentées. Les données de 152 thermographies des satellites NOAA-6 et NOAA-7 sont confrontées aux théories récentes sur les remontées d'eau au voisinage des caps (Crépon et Richez, 1982; Crépon et al., 1984); elles conduisent à une description générale des mouvements marins et des remontées d'eau dues aux vents dans la région.
