: Abstract Beach nourishment is now widely used as a "soft" coastal protection but its performance still relatively poorly understood. monitoring allows analysis over range of environmental conditions which, in turn, can provide the basis for successful design and implementation. Remote sensing techniques based on Structure-from-Motion (SfM) have been successfully geomorphological studies environments, including gravel beaches (James et al., 2013). This paper presents applications SfM to two nourished Croatia. The different were monitored using "remote platforms". First, larger natural embayed beach was surveyed by unmanned aerial vehicle (UAV). Secondly, an artificial pocket pole-mounted hand-held camera from ground. These cases demonstrated that method has many advantages comparison with traditional methods providing high-resolution 3D data, being easy implement affordable. Hence it great potential regular surveys Croatia deliver process understanding required inform implementations schemes.
