ABSTRACT
The relationship and interaction between a river’s flow magnitudes and hysteresis and it’s mor-phodynamic behavior in general (as defined by bedload and suspended load) have been the subject of many studies and has proven to be both of a complex nature and hard to define. The following paper aims to analyze the morphodynamic behavior of rivers when subjected to the effects of hysteresis which results from the naturally changing flow. Common approaches in engineering often rely on the assumption of gradually varying flow which does not account for hysteresis’ effects, leaving the associated error unquantified. In this paper, an attempt was made at verifying the presence and assessing this error via multivariate analysis applied to an open database. Significant proof is presented to the importance of hysteresis as a predictor for sediment transport and how its use can improve upon most common methodologies for defining sediment transport.
