**About the Editors**

**Salvatore Manfreda** (Prof.) is a Full Professor of Water Management, Hydrology and Hydraulic Constructions at the University of Naples Federico II. He is currently the Chair of the COST Action HARMONIOUS and the Scientific Coordinator of the Research Grant aimed at the Development of the Flood Forecasting System of the Basilicata Region Civil Protection. His research activities focus on distributed modeling, flood risk, stochastic processes in hydrology and UAS-based monitoring.

**Caterina Samela** (Dr.) is a Researcher at the National Research Council of Italy—Institute of Methodologies for Environmental Analysis (CNR—IMAA). She has a PhD in the fields of Hydrology and Hydraulics and her primary interests are related to hydroinformatics, geomorphic analysis, machine learning, GIS and data-scarce environments. Her research activity focuses on the definition of data-driven methods with applications in multiple fields, including fluvial and pluvial flood risk assessment, hydrological models and river monitoring.

**Alberto Refice** is a researcher at the Italian Consiglio Nazionale delle Ricerche (CNR)—Istituto per il Rilevamento Elettromagnetico dell'Ambiente (IREA). His main research interests concern advanced processing techniques for remotely sensed data, especially synthetic aperture radar (SAR). He is currently working on remote sensing applications such as environmental hazard monitoring and management, geo-hydrological process monitoring and modeling, and landscape evolution.

**Valerio Tramutoli** (Prof.) is an Associate Professor at the School of Engineering of University of Basilicata where (since 1997) he teaches courses on Satellite Remote Sensing and General Physics. He has been the national coordinator of the SEISMASS Project (funded by ASI) PI, and responsible for DIFA participation in several international projects funded by NATO and by EC in the framework of the Science for Peace, FP6-IST, FP6-INTAS, FP6+FP7 GMES initiatives. During the period 2010–2011, he was the coordinator of the European project PRE-EARTHQUAKES funded by the EC in the framework of the FP7-GMES-Space Program. His research activity has been focused on the development of new satellite sensors and techniques for natural, environmental and technological hazards forecast, monitoring and mitigation.

**Fernando Nardi** (Prof.) is an Associate Professor at the University for Foreigners of Perugia where he has also served, since 2016, as the Director of the Water Resources Research and Documentation Centre (WARREDOC). Since 2017, Dr. Nardi has been the chair of the Citizens and Hydrology (CANDHY) working group of the International Association of Hydrological Sciences (IAHS). Since 2019, he has been a Courtesy Affiliate Professor at the Institute of Environment and at the UNESCO Chair on Sustainable Water Security of Florida International University (FIU). His scientific interests focus on hydrologic–hydraulic modeling, hydrologic prediction in ungauged basins, geomorphic floodplain mapping, 2-D flood modeling, geospatial information systems and algorithms, Open/Big Data and Citizen Science.
