Turbulent flows are usually studied from two separate perspectives. The first is a global perspective in which the energy cascade and energy flux across scales are studied in spectral space. A defining feature of this analysis is the statistical locality of interactions among scales that contribute to the energy flux in scale space. The second is the physically local perspective, most prevalent in wall-bounded turbulent flows, where the kinematics and dynamics of individual eddies or coherent structures are analyzed. In this dissertation, we combine the coherent-structure and scale-by-scale energy-transfer perspectives while explicitly accounting for temporal dynamics.  We focus primarily on the hierarchy of attached structures in the logarithmic region of wall-bounded turbulence. The study was conducted in a turbulent channel flow at a friction Reynolds number of 2000.
