DOI: 10.1016/j.rse.2018.03.006
Abstract: Abstract Climate change projections foresee an increasing number of intense precipitation events with consequent flash and riverine floods. An accurate and rapid mapping of these phenomena is a key component of effective emergency management and… read more here.

DOI: 10.1109/jstars.2022.3152127
Abstract: In this study, the effectiveness of several convolutional neural network architectures (AlbuNet-34/FCN/DeepLabV3+/U-Net/U-Net++) for water and flood mapping using Sentinel-1 amplitude data is compared to an operational rule-based processor (S-1FS). This comparison is made using a… read more here.

DOI: 10.1109/tgrs.2022.3199036
Abstract: Due to the complexity of backscattering mechanisms in built-up areas, the synthetic aperture radar (SAR)-based mapping of floodwater in urban areas remains challenging. Open areas affected by flooding have low backscatter due to the specular… read more here.

DOI: 10.3390/hydrology10040091
Abstract: Floods are lethal and destructive natural hazards. The Mediterranean, including Greece, has recently experienced many flood events (e.g., Medicanes Zorbas and Ianos), while climate change results in more frequent and intense flood events. Accurate flood… read more here.

DOI: 10.3390/hydrology8020065
Abstract: The height above nearest drainage (HAND) model is frequently used to calculate properties of the soil as well as predict flood inundation extents. HAND is extremely useful due to its lack of reliance on prior… read more here.
