“…The upper Cretaceous limestones vary in thickness between 150 and 200 m. The basins around Kastrouli and the Desfina valley are filled with Quaternary, mainly Holocene sediments [19,34,35].…”

The Kastrouli Late Bronze settlement in Phocis province, central Greece, has been proved to have been an important center in the periphery of the Mycenaean palaces. It was reused at least partially and was cultivated until the 20th century. The presence of a flat area off the Kastrouli hill and the seasonal flooding nowadays led to the present investigation, questioning the formation of an ancient lake or marsh/swamp. A methodological approach was applied combining the digital elevation model (DEM) and GIS of the wider and confined area, examining slopes between 0 and 5 degrees (0 and 8.75%), with electrical resistivity tomography (ERT) traverses of around 300 and 500 m, reaching a depth of 100 m. The ERT data were rapidly collected on profiles and provided a cross-sectional (2D) plot. It was found that, in the area, there is a basin with a length of 100 m and a depth of around 40–50 m. The sedimentation process over the millennia has filled the basin, with the upper 5–6 m surface layers of the area having a low resistivity. The presence of two natural sinkholes with apparent engineered hydraulic works is noted to conform to drainage and produce a habitable environment, protecting the cultivated land and avoiding a swamp associated with health issues.

“…Rockfalls are more common in Western Greece, due to a combination of factors related to topography, geological and tectonic conditions, climate and human activities (Koukis et al, 1994). Indicatively, recent rockfall incidents occurred at Monemvasia historical site (Saroglou et al, 2008), at the archaeological site of Delphi (Marinos et al, 2005) and the severe rockfall at Tempi Gorge on the 17 th of December 2009, which led to one human life loss and caused major problems on the national road network between Athens and Thessaloniki (Gazetas et al, 2010).…”

Rockfall hazard and risk assessment of road slopes.

This paper presents and compares the main methods of hazard and risk assessment for road slopes. Hazard assessment is achieved by rating several parameters such as the slope’s geometry, traffic conditions, the geology and the rockmass properties, weather conditions, historical rockfall data etc. A hazard assessment can also be executed using 2D or 3D trajectory models, by combining the frequency of a rockfall and the kinetic energy of a falling rock. Several methodologies have been developed for risk assessment, varying from simplistic approaches to comprehensive probabilistic or quantitative risk assessment methods. Finally, the most suitable methods were used in order to assess the level of hazard and risk as an example (the data from two sections of the national road at Tempi Gorge, Greece) where many rockfall events occurred in the past few years.

“…Geotechnical problems related to slope instability and the protection of historical sites in Greece have been addressed by several authors (Marinos and Koukis, 1988) and recently, among others, by Marinos et al (2002) and Marinos and Rondoyanni (2005). The hazard of rockfalls is obviously higher in areas with intense seismic activity, where earthquakes are the principal triggering factor (Marinos and Tsiambaos, 2002).…”

Abstract. The paper presents the kinematics of rock instability of a high limestone promontory, where the Monemvasia historical site is situated, in Peloponnese in Southern Greece. The instability phenomena poses a significant threat to the town located at the base of the slope. Rockfall episodes occurred in the past due to the relaxation of the high cliff, whereas significant undermining of the castle frontiers has been observed at the slope crest.The predominant types of instability are of planar, wedge and toppling failure of medium to large blocks. In order to investigate the existing stability conditions and decide upon the protection measures, stability and rockfall analyses were carried out for numerous slope sections under different loading conditions and protection measures were suggested.A rock-fall risk rating system is proposed, which is based on morphological and structural criteria of the rock mass and on vulnerability and consequences. The rating system is applied for individual sections along the slope and a risk map was produced, which depicted areas having different degree of risk against rockfall occurrences.
