“…Using the reduced complexity model of delta morphodynamics DeltaRCM (Liang, Geleynse, et al, 2015;Liang, Voller, & Paola, 2015;Liang, Kim, & Passalacqua, 2016;Liang, Van Dyk, & Passalacqua, 2016), we investigate the influences of permafrost and landfast ice on river delta morphology, growth, and channel dynamics. By simplifying physical processes for incorporation into this rule-based model (Murray, 2003), we gain insights into the processes and process interactions most important to Arctic river delta dynamics, which would be difficult to obtain through other methods (e.g., remote sensing or field observations).…”
