Brief Communication: The use of an unmanned aerial vehicle in a rockfall emergency scenario
Summary: In recent years, the use of unmanned aerial vehicles (UAVs) in civilian/commercial contexts is becoming increasingly common, also for the applications concerning the anthropic and natural disasters. In this paper, we present the first results of a research project aimed at defining a possible methodology for the use of micro-UAVs in emergency scenarios relevant to rockfall phenomena.

Spatial and seasonal responses of precipitation in the Ganges and Brahmaputra river basins to ENSO and Indian Ocean dipole modes: implications for flooding and drought
Risk to life due to flooding in post-Katrina New Orleans
Summary: After Hurricane Katrina in 2005, New Orleans’ hurricane protection was improved to withstand a 1/100 per year hurricane. This paper quantifies the risk to life in post-Katrina New Orleans. When compared to risks of other large-scale engineering systems (e.g. other flood prone areas, dams and the nuclear sector) and acceptable risk criteria, results indicate the risk to life is significant. Results and methods of this study can inform future flood protection management and risk communication.
Landslide susceptibility near highways is increased by 1 order of magnitude in the Andes of southern Ecuador, Loja province
Summary: Mountain roads in developing countries often increase landslide occurrence. In this study, landslide initiation frequency along interurban highways was investigated in the Ecuadorian Andes across different climates. Using statistical models, landslides were found to be about 20 times more likely to occur in close proximity to highways compared to areas in 200m distance from highways while accounting for other environmental factors. Road effects appear to be enhanced in some geological units.
A new high-resolution BOLAM-MOLOCH suite for the SIMM forecasting system: assessment over two HyMeX intense observation periods
Summary: In the HyMeX framework, an intercomparison study of two different configurations of the ISPRA hydro-meteo-marine forecasting system (SIMM) has been performed to assess the forecast skill in predicting high precipitations and very intense storm surges over the northern Adriatic Sea (acqua alta). The results show an objective added value of the use of high-resolution meteorological models, and they suggest the opportunity to develop a time-lagged multi-model ensemble for the acqua alta prediction.
Numerical simulation of a rare winter hailstorm event over Delhi, India on 17 January 2013
Summary: This study analyzes the cause of the rare occurrence of a winter hailstorm over New Delhi/NCR (National Capital Region), India. The absence of increased surface temperature or a low level of moisture incursion during winter cannot generate the deep convection required to sustain a hailstorm. Consequently, NCR shows very few cases of hailstorms in the months of December-January-February, making the winter hail formation a question of interest.
Numerical experiments of storm winds, surges, and waves on the southern coast of Korea during Typhoon Sanba: the role of revising wind force
Summary: We report the results on the effectiveness of an improved approach to surge and wave simulation by revising wind force. We tested the wind dissipation effects caused by land roughness with various land use types near the coast for wind field generation. As a result, better agreement between the simulated and measured storm winds have been found when considering wind dissipation effects. This modified wind force leads to clearly improved results for storm surge and wave simulation.
The connection between long-term and short-term risk management strategies for flood and landslide hazards: examples from land-use planning and emergency management in four European case studies
Summary: Adaptation to unforeseen, hazardous events requires the implementation of purposeful risk reduction strategies that aim at both taking effective measures and using funds most efficiently. Coordination of long-term and short-term risk management strategies is considered crucial. This research discusses current problems and indicates benefits to establishing or strengthening the link between spatial planning (long-term perspective) and emergency management authorities (short-term perspective).
