The potential of instability indices in assessing atmospheric instability is examined for the areas of Attica, Thessaly and Central Aegean and Crete, Greece. Generally, many indices have been develope...
Development of dike fragility curves for piping and micro-instability breach mechanisms
dike fragility curves piping and micro-instability breach mechanisms
2009/12/8
The paper analyses the prevailing breach mechanisms of fluvial dikes. Piping in the dike foundation and slope failure as a consequence of seepage flow through a dike core (micro-instability) were iden...
Identification of active release planes using ground-based differential InSAR at the Randa rock slope instability, Switzerland
active release planes ground-based differential InSAR the Randa rock slope
2009/12/31
Five ground-based differential interferometric synthetic aperture radar (GB-DInSAR) surveys were conducted between 2005 and 2007 at the rock slope instability at Randa, Switzerland. Resultant displace...
Model of oscillatory instability in vertically-homogeneous atmosphere
Model oscillatory instability vertically-homogeneous atmosphere oscillatory behaviour

The 2-D version of the non-hydrostatic fully compressible model MOLOCH developed at ISAC-CNR was used in idealized set-up to study the start-up and finite amplitude evolution of symmetric instability....
Mesoscale convective systems in Spain: instability conditions and moisture sources involved
Mesoscale convective systems Spain instability conditions moisture sources
2010/1/28
Source-receptor water vapor content areas are analyzed for a particular case of deep mesoscale convective system (MCS) developed over the Mediterranean margin of Spain in October 1982. The aim of this...
Atmospheric instability analysis and its relationship to precipitation patterns over the western Iberian Peninsula
Atmospheric instability analysis relationship precipitation patterns Iberian Peninsula
2010/1/26
Thermodynamic and dynamic atmospheric stability indices will be analysed in order to classify the rainfall types occurred in western Iberia and provide information about the associated meteorological ...

Synoptic situations producing rainfall at four rawinsonde observatories at eastern Spain are classified as stratiform or convective depending on dynamic and thermodynamic instability indices. Two dail...
Infiltration,seepage and slope instability mechanisms during the 20–21 November 2000 rainstorm in Tuscany,central Italy
Infiltration seepage slope instability mechanisms
2009/12/30
On 20–21 November 2000, a storm of high intensity, with a estimated return period of more than 100 years, triggered over 50 landslides within the province of Pistoia in Tuscany (Italy). These failures...
Softening and instability of natural slopes in highly fissured plastic clay shales
Softening instability natural slopes highly fissured plastic clay shales
2009/12/29
Softening is often considered to be the main cause of first-time slides in OC clay, but so far the mechanics of softening has not been satisfactorily explained. Bearing on laboratory data and field ob...
Analysis of infiltration, seepage processes and slope instability mechanisms during the November 2000 storm event in Tuscany

2010/1/22
On the days 20-21 November 2000, a storm of exceptional intensity triggered over 50 landslides within the province of Pistoia in Tuscany (Italy). These failures are mostly of complex type, originating...
