Effect of the dependence structure and time irreversibility of streamflow in flood inundation mapping with focus on the long-term persistence behaviour

(Corresponding) Dimitriadis P., Iliopoulou T., Papanicolaou P., Koutsoyiannis D.

Topic:

Floods, droughts and water scarcity

The marginal structure of streamflow, with focus on the right tail behaviour, is considered as the main factor in flood risk assessment, while little is known on the effect of the temporal dependence structure and irreversibility of streamflow. Interestingly, the second-order dependence behaviour...Read more

Simulation of an urban flash flood: the 2017 flood event in Mandra, Attica

Handrinos S., (Corresponding) Bellos V., Sibetheros I.

Topic:

Floods, droughts and water scarcity

This study deals with the 2D flood simulation of an urban flash flood event that took place on November 15, 2017 in Mandra, Attica. The well-known hydrodynamic software HEC-RAS was used for the flood simulation. The model input was an ensemble of 100 hydrographs, derived from the simulation of the...Read more

Analysis of the hydrologic conditions during the flood event occurred in Mandra, Greece, on November 2017

(Corresponding) Feloni E., Theochari A., Skroufouta S., Bournas A., Baltas E.

Topic:

Floods, droughts and water scarcity

On November 15, 2017 a flash flood struck West Attica with intense effects in the settlement of Mandra, causing human losses as well as extensive material damages. The aim of this work is to examine this flood event from a hydrological perspective in order to highlight the diversity of estimations...Read more

Evaluation of urban flood characteristics through the spatial analysis of flood-related factors and flood incidents recorded in the western side of Athens basin on October 24, 2014

(Corresponding) Feloni E., Anayiotos A., Baltas E.

Topic:

Floods, droughts and water scarcity

On October 24, 2014, a severe flood event took place in the entire Athens basin with extensive damages due to a short-duration rainfall event of high intensity. This work focuses on the analysis of the characteristics of this specific flood event by investigating the influence of various factors on...Read more

Evaluating flooding impact to riverine bridges. The case of the Historical Bridge of Arta in Epirus, Greece

(Corresponding) Panagiotatou E., Mitsopoulos G., Stamou A.

Topic:

Floods, droughts and water scarcity

ABSTRACT Climate impacts are expected to intensify weather related flooding events that are the most common and damaging natural disaster. Riverine bridges are particularly prone to failure during floods and their disruption may impair significantly flood evacuation plans. Thus, in the design of...Read more
