Query: Investigation Of The Hydro-Meteorological Hazards Along The Bulgarian
  Coast Of The Black Sea By Reconstructions Of Historical Storms   Information about the hydro-meteorological parameters during the extreme sea
storms is of significant importance for the sustainable development in the
context of flood risk for the coastal areas. Usually there is a lack of
sufficiently long history of instrumental measurements of the extreme winds,
waves and storm surges. Simulation of historical storms is an important tool to
evaluate the potential coastal hazards. In the absence of measured data
hindcasts can satisfy the need for historical data. The wave and storm-surge
regional numerical simulations have been carried out for the ten most severe
storms over the Bulgarian coast of the Black Sea from the period 1972-2012. The
ERA-Interim and ERA-40 reanalysis of wind at 10 m and mean sea level pressure
have been downscaled with a high resolution atmospheric model ALADIN to the
horizontal and time scales suitable for precise evaluation of
hydro-meteorological parameters during the storms. The downscaled fields of
wind and sea level pressure have been used as input for the wave and storm
surge models.
