“…It is remarkable that this value is very close to the corresponding value of the World Meteorological Organization (WMO) reference period 1961-1990 (397 (Lasda et al ., 2010), the frequent and intense precipitation events in September due to atmospheric instability and also the extreme precipitation events during November and December 2002. The driest year of the record is 1898 (115 mm), while the period 1989-1990 was the driest period of the whole record (accumulated precipitation, 350 mm).…”

The observed and projected precipitation variability in Athens is assessed for a 2.5 century period. The observed variability is examined using the 150-year historical record of the National Observatory of Athens, while future variability using an ensemble of regional climate models. A good agreement between observations and the model ensemble was found for annual and seasonal precipitation. The model ensemble overestimated the number of rainy days and precipitation amount corresponding to light precipitation and underestimated them corresponding to moderate-heavy precipitation. A 35% decrease in total annual precipitation coupled with an increase in extreme precipitation was projected by the model ensemble up to 2100.

“…The high recurrence and number of flash floods per area is related to rapid with no planning and widespread housing developments. In addition, the mitigation strategy for the prefect seems to be reactive instead of proactive and preventive with little organization and coordination that is unlikely to stop flash floods [30]. At the same responsible authorities appears to not take under consideration the anticipated increase in intensity and rapidity of rainfalls due to climate change at the Attica basin.…”

Nowadays the appearances of water extremes are frequently observed mainly because of anthropogenic and climate change influences. These extremes cause various impacts on the environment. With respect to river systems, floods are such events that are characterized with increasingly untypical high water levels that overflow river beds. In many cases, they cause extremely harmful impacts to human societies, accompanied with serious environmental damages and modifications. This paper focus on the problems connected to flood appearances and some of their possible related impacts on river systems. To better understand these, phenomenon main specifics with regard to its occurrence, behavior and possible consequences are summarized. Most commonly used methods for flood assessments are presented. Some real case floods and their impacts on the river hydraulics from the Balkans are briefly presented. To better explain floods and the reason-outcome-mitigation nexus related recent required and adopted EC, Bulgarian and Greece policies and practices in the area are outlined concisely with regard to prevention measures in the form of early warning systems, river restoration etc. The presented information address the experts in regards to knowledge, practices dissemination and enhancement, and the connection between experts and responsible decision makers that deal with flood mitigation and prevention.

“…The area was affected by several flash floods events in the past 20 years, especially in 1993, 1994, 2002 and 2005. The 1994 event (included an 11 h total rainfall duration) affected the whole Attica region with a probably of occurrence of 1/500 years (Lasda et al 2010). The maximum total accumulated point rainfall was 131.2 mm with a 67.7 mm/h maximum intensity over time of concentration (Lagouvardos et al 1996;Llasat et al 2010).…”

Multi-vulnerability analysis for flash flood risk management

et al. 2016

Vulnerability assessment implies a quantitative evaluation of the individual vulnerability components such as elements at risk, their physical exposure and social characteristics. Current approaches in vulnerability research are driven by a divide between social scientists who tend to view vulnerability as representing a set of socio-economic factors, and scientists who view vulnerability in terms of the degree of loss to an element at risk. To close this gap, a multi-dimensional vulnerability analysis has been undertaken focusing on flash flood hazards in Greece. To represent physical vulnerability, an empirical relation between the process intensity and the degree of loss was established. With respect to social vulnerability, an assessment was undertaken by means of empirical data collection based on a door-to-door survey. In general, both physical and social vulnerability was comparable low, which is interpreted as a result from (a) specific building regulations in Greece as well as general design principles leading to less structural susceptibility of elements at risk exposed, and (b) a relatively low economic loss leading to less social vulnerability of citizens exposed. It is shown that a combination of different perspectives of vulnerability will lead to a better understanding of perceptions of actors regarding their vulnerabilities and capacities.
