The study area, called Kamchia-Shkorpilovtsi, is situated in the western Black Sea, and spreads from cape Paletsa to cape Cherni Nos (Figure 9.1), located 25 and 40 km to the south of Varna city, respectively. It comprises the longest and the largest sandy beach along the Bulgarian Black Sea coast, with well-developed dunes and the two rivers' mouths, these of the Kamchia River and the Fundakliiska River. In the middle of the site, near the mouth of the Fundakliiska River a scientific pier is built perpendicularly to the shoreline, reaching 4.5 m water depth. The beach is formed as a result of accumulation of erosive and fluvial sediments. The main morphological feature of the study area is its rectilinear shoreline with almost parallel isobaths. The bottom slope is covered with sands of different size. In its upper part down to 2.5 m depth, over 95\% of bottom sediments consist of coarse and medium sand fractions. As the depth grows, the content of these fractions decreases and at 8-10 m over 90\% of the sediment grain size is less than 0.25 mm.
The beach is open to waves of the eastern half. In the case of severe storms the wind speed magnitude can reach 35-40 m/s and 9 m height of maximum significance wave at depths of about 1000 m. The large seasonal variability is one of the most marked features of the wave climate. The winter storms are much more frequent than the summer ones. In the western Black Sea the most frequent are the winds from northeast and east, which trigger the most severe storms.
In the beginning of March a short but very intense storm occurred in the western Black sea. This event was distinguished with all features of the severe storms known from the historical overview well defined phases growth took place on 08.03, peak 09.03 and decay 09.03 - 10.03. Wind and wave direction were quite stable turning from ESE to ENE. Maximum SWH reached almost 4.20 m.

Model results for this storm are shown in \autoref{fig:MICORE_Kamchia_Shkorpilovtsi_Beach_pr04_profiles}.

% if interpret:

Both models predict washing out of the upper part of the profile, but XBeach overestimates it significantly. Both models predict re-deposition of eroded material downward the profile, while in reality such accretion was not observed. Both models predict washing out of the permanent bar, and both of them underestimate the erosion rate.
