                         Asymmetrical Fragmentation Operator (FA)to characterize 
                         geomorphological controls that affecty hydro electrical 
                         reservoirs. Landsat-TM images were used to map reservoirs flooded 
                         surface. The FA operator was applied to vector files describing 
                         reservoirs shape to compute the average FA for each reservoirs. 
                         The reservoir database were then classified according to 
                         reservoirs hydrographic basin and reservoirs size. The FA values 
                         were compared to the Shoreline Development Index (D)and to the 
                         reservoirs primary productivity data available in the literature. 
                         Results show that the FA is able to detect high-resolution 
                         geomorphologic features, which are not detected by D. Preliminary 
                         results indicate also that there is a no significant relationship 
                         between FA and the primary productivity. This fact, however, does 
                         not hold for D. Moreover, FA showed no sensitivity to reservoirs 
                         size, being more responsive to their position in the cascade 
                         system, and therefore to the hydrographic basin geomorphology.",
