Understanding fluvial processes in rivers and streams and their interactions with each other enable for more effective channel designs, improved erosion control measures, and more resilient systems. The use of an unconfined river basin flume (5.6 m in length x 1.9 m in width) allowed for analysis of the interactions between sediment transport rates, bed development, and planform morphological adjustments in an unconfined alluvial meandering stream. Three tests were completed including one quasi-unsteady hydrograph experiment. It was found that the largest bank morphological adjustments coincided with considerable bed development and sediment transport rates; agreeing with previous field and laboratory observations. Morphological evolution appears to follow an exponential growth profile, with the majority of bed development and bank erosion occurring during the early stages of a run or during the rising limb of the hydrograph. Results from this research proposed relationships between discharge, sediment transport and channel morphology in alluvial meandering streams.
