ABSTRACT

The paper describes the existing operational system of NIMH- BAS for the sea state
forecast in the Black Sea and our current progress on the implementation of an
additional component for the wave forecasts in the Bulgarian Black Sea coastal zone.
Waves and especially the extreme ones, occurring during severe storms are a major
hazard for the coastal zone, causing significant damages to the infrastructure, threat for
the human lives and also causing significant damages to the protected areas around the
coast. The numerical model WAVEWATCH III have been for wind waves forecasts for
the entire Black Sea with horizontal resolution of 1/8 degree ( roughly 14 kilometers),
which is sufficient for the open sea, but not enough for a detailed coastal wave
forecast. For the purposes of the coastal wave forecasts and early warnings in case of
severe storms we decided to implement SWAN (Simulating the Waves Near Shore)
wave model- development of TU- DELFT. In this paper we will describe the brief
details about the coastal sea state forecasting system of NIMH- BAS and a case study of
the storm of 07-08 February 2012, which is the severest storm in our coastal area for the
last decade (and probably longer period).
