4. RESULTS AND CONCLUSIONS 
Stability of stone covered armoring layer under the waves and 
currents also both were investigated during this study by 
experimentally. Given stones sizes for armoring layer are 
satisfied the design criteria and there is no possible damage 
occurred under the mentioned flow conditions. 
This study figures out of an application of digital 
photogrammetry and image processing for engineering 
purposes. The first investigation is widely used and well-known 
technique with its instruments, measurements and methods. The 
originality of the study is the second investigation and 
monitoring of probable displacement of the armor stone. This 
method must be supported with advanced image processing 
techniques and the displacement analysis must be set onto a 
mathematical basis. In that way, a new method for 
photogrammetrical displacement and deformation analysis, 
which is full-automatic, can be developed. 
The characterization of the sea bottom stable conditions in the 
large coastal area is almost impossible by using classical 
experiment techniques done in the laboratories. If it is consider 
that there are many stone with different sizes. It is possible to 
say that the reliability of the results obtained by classical 
methods may be very low. In this study, it has been shown 
proposed and verified method in order to solve an important 
design problem in coastal areas.
