<Para ID="Par1">Water Scarcity encompasses both permanent and occasional water resources shortages. Measures to combat water scarcity are of different nature dependent on whether they intend to withstand permanent or occasional water deficiency. It is the aim of this paper to discuss and propose a systematic...</para>

Floods in built-up areas are among the most catastrophic natural hazards mainly due to the high value properties existing in these areas. The most vulnerable areas are the riverine areas with mild terrain which are often encountered in the coastal zone. Due to the mild terrain and the...

In this paper, a new powerful numerical hydrodynamic in-house model is presented and tested. The model simulates flood routing in two dimensions. It is based on the solution of Shallow Water Equations using the Finite Difference Method according to the explicit McCormack numerical scheme which...

The delineation of the areas exposed to flood hazard caused by a dam existence upstream and its possible failure needs a thorough analysis of the hypothetical dam break incident. The study presented in this paper focusses on the simulation of the dam breach formation and the calculation of the...

Conventionally drought severity is assessed based on drought indices. Recently the Reconnaissance Drought Index (RDI) was proposed to assess drought severity based on the precipitation to potential evapotranspiration ratio (P/PET). In this paper RDI is studied as a bivariate index under a set of...

The study presents a multicriteria method incorporating a fuzzy set approach and the 0/1 programming for selecting the most appropriate actions for facing long term water scarcity in a water system under a set of objectives and constraints. The proposed method includes also the right of veto...
