Use of ergodic reasoning to reconstruct the historical range of variability and evolutionary trajectory of rivers

摘要: Applications of ergodic reasoning (or location for time substitution) aid efforts at environmental reconstruction and prediction, providing a useful tool to analyse communicate stages landscape evolution. Analysis the historical range behaviour change that river system has experienced can be used interpret thresholds have been breached, underlying controls and/or triggers adjustment change. This information forecast future trajectories provide target conditions management activities. paper uses case study from upper Wollombi Brook, New South Wales, Australia demonstrate how assess behaviour, responses natural human-disturbances. The ‘river evolution diagram’ developed by Brierley Fryirs (Geomorphology River Management: Styles Framework. Blackwell Publishing: Oxford, 2005) is presented as means depicting evolutionary variability this river. These approaches readily applied in other systems. Implications analysis are outlined.
