%X The lakes and reservoirs morphometry as surface shape, surface area, underwater form, depth, and the irregularity of their shoreline have a major impact on turbulence, water stratification, sedimentation and resuspension, and the extent of littoral-zone wetlands that determine lake and reservoir functioning. The degree of irregularity is most frequently estimated from the shoreline development factor that reflects the extent to which the measured shore length is greater than the length of the circumference of a circle of an area equal to that of the lake. As indicated by Assireu et al. (2004), this index is not able to detect high-resolution geomorphologic features. In this work we present a dynamical morphometric index, based on recognition pattern techniques, which enable us to identify, for each wind direction, what are the reservoir regions not subject to wind-induced turbulence.
