Experimental parameters were held constant for the duration to isolate the internal flow-sediment feedback processes while excluding allogenic forcing. Experimental results indicated that intermediate scales represent a significant source of formative fan processes via a cyclic feedback. The morphodynamic feedback cycle consists of: (1) sheet-flow and aggradation, (2) channel initiation, (3) channel narrowing and extension, (4) flow expansion and lobe deposition, and (5) flow reorganization. Hydraulic data was collected using Large Scale Particle Image Velocimetry (LSPIV) and a dye-intensity method while topographic data was collected using a terrestrial LiDAR unit. Using this data, the intermediate scale cycle was examined with a focus on the hydraulic context. Cycles exhibited a hierarchy of scales with relative independence between the spatial and temporal.<a name="_GoBack"></a><o:p></o:p></p><p class=MsoNormal><span style='font-size:11.0pt'><o:p> </o:p></span></p></div></body></html>
