A benchmark dataset for the flood event of Mandra (Athens, Greece), 2017

This dataset includes:

1) The maximum water depths recorded at the 44 points after the flood event which hit Mandra, Athens, Greece (15th of November 2017) with their coordinates in both GGRS87 (Greek Geodetic System) and WGS84 systems. Besides, the simulated maximum water depths as derived by the HEC-RAS software (which is calibrated) and the MIKE FlOOD software (informed by the calibrated HEC-RAS).

2) The Digital Terrain Model (DTM) of the greater area with a resolution of 5 m, as provided by the National Cadastre and Mapping Agency of Greece.

3) Two Shape files with (a) the computational area and the (b) upsream/boundary conditions used for both calibrated HEC-RAS and informed MIKE FLOOD software.

4) A shape file with the Mandra urban blocks footprint, as were manually drawn on Google Earth platform.

5) The ensemble of 100 hydrographs which serve as the inflow from Agia Aikaterini catchment to the Mandra town. They are derived by implementing the FLOW-R2D hydrodynamic simulator at the catchment scale, having as an input the rainfall field captured by the weather radar during the Mandra flood event (Bellos et al., 2020).  

6) The rainfall field of the greater area with a spatial resolution of 200 m and a temporal resolution of 2 min, recorded by the X-band weather radar of the National Observatory of Athens (Bellos et al., 2020).
