The identification of flood‐prone areas is a fundamental component of rational urban planning and proper natural disaster management policy. The aim of the present study is to introduce a framework for the identification of flood‐prone areas using GIS techniques and decision making, based on a comparative evaluation for various scenarios. As a case study, the Attica region in Greece is selected, which is occasionally affected by heavy rainfall, the main cause of flooding in the region, coupled with the fact that human activities and urbanization of recent years play a significant role in flood occurrence. In this context, the development and application of a GIS‐based multi‐criteria analysis method for the determination of areas susceptible to flood events is initially presented. The entire spatial analysis is performed using SAGA 6.3.0 and ArcMap 10.2 Desktop, by applying a number of alternative modifications and, finally, by evaluating different scenarios regarding methods for the criteria standardization, criteria hierarchy and factors’ weighting estimation. The proposed framework has an advantage among other approaches, since it takes into account mainly static data that are linked to flooding, such as the topography and land cover distribution and it can be easily customized in ungauged catchments.

Five different water resource management scenarios are examined on eight dry islands of the Aegean Sea in Greece, pitting the current practice of water hauling via ship against alternative water supply schemes in delivering a sustainable solution for meeting water demand. The first scenario employs current water supply practices along with the operation of domestic rainwater harvesting systems. Desalinated water, provided through the operation of wind-powered desalination plants, is considered the main source of potable water in the rest of scenarios. Wind-powered desalination may be combined with rainwater harvesting as a supplementary source of water and/or seawater pumping and an additional source of energy that is supplied to the system. All different alternatives are evaluated for a 30-year lifespan, and an optimal solution is proposed for each island, based on a life cycle cost (LCC) analysis. The performance of this solution is then assessed under six climate change (CC) scenarios in terms of the rate of on-grid versus off-grid renewable energy that is required in order to achieve a certain reliability level. Overall, the examined scenarios show a decreasing performance in terms of reliability under CC for the eight islands.

Attica, which is the region with the largest population in Greece, suffers from numerous high rainfall intensity events inducing flash floods and, consequently, significant damages in the urbanized areas. High rainfall intensities are frequently connected with convection, a quiet often phenomenon during either the transitional seasons or the late summer thunderstorms. The objective of this paper is to implement and evaluate a stratiform-convective classification technique for the rainfall events occurred in Attica during the period 2005–2016. As this methodology requires only the precipitation records, the satisfactory evaluation of this classification approach allows further applications, such as, a climatological analysis regarding convective and stratiform trends in the study area and generally in Greece. Particularly, the rain gauge stations' records used correspond to 10-minute time series from 32 rainfall stations for the same period, and these data are analyzed and processed in order to fit a suitable exponential curve describing the stratiform component. A critical annual threshold of rainfall intensity in mm/6h is then calculated, separating the prevailing convective and stratiform regime above and below this value, respectively. The analysis is performed in three individual subareas of Attica region demarcated initially according to their morphological characteristics and subsequently by checking the cross-correlation for each pair of stations. This critical intensity threshold is determined for each year separately, in order to illustrate the uncertainty and the difficulty in identifying a standard threshold, as it is related to the annual behavior of precipitation. Using this threshold, a total of about 180 six-hour case events is detected as purely convective cases, however this number ranges for each subarea. For these cases, a further analysis is performed with the aim of verifying their convective character. Verification includes time-accurate lightning data, surface synoptic observations from the Hellenic National Meteorological Service and six-hour surface analysis charts from UK MetOffice. Findings, which are presented via indicative verification indices, show in general encouraging performance, considering the highly variable nature of convective precipitation which poses considerable problems in its identification with quite simple techniques.

Adequate and accurate hydrometeorological data are very important for performing a range of hydrologic purposes, including water resources management, assessment of the impacts of climate change, and flood forecasting and warning. The rational prevention of natural disasters, such as floods and droughts, is strongly connected with a forecasting technology which cannot be achieved without hydrometeorological observations. The existence of a dense network of instruments is required in order to be able to model, predict, and plan for catastrophic events which have obvious negative impacts on public health and socioeconomic aspects; however, this entails large installation and operational costs. This paper presents a multicriteria geographic information system (GIS)-based approach for the optimization of a station network, with the aim of establishing an optimal hydrometeorological station network in the Florina region of northern Greece, both for developing an up-to-date real time flood warning system and for water resources management, especially in agricultural areas.

The objective of this study is the analysis of heavy precipitation events occurred in Attica region during the period 2007–2013, along with the determination of their characteristics depending on the season and their corresponding impact. These events were selected according to two criteria; the lightning occurrence—information that was acquired from the Hellenic National Meteorological Service Precision Lightning Sensors Network (HNMS-PLN)—and the high rainfall intensity, provided by the Hydrological Observatory of Athens (HOA) rainfall network. On the one hand, the composite means and anomalies of the respective synoptic conditions, which were based on the reanalysis data sets acquired from the National Centers for Environmental Prediction–National Center for Atmospheric Research (NCEP–NCAR), along with the frontal activity over Greece, have been analyzed. On the other hand, special attention has been given to the configuration of specific instability indices, during the examined rainfall events. The aforementioned study is an effort to shed light to the rainfall events’ features, with respect to their seasonal incidence and their relation to phenomena such as floods and hail.
