An Arctic-delta model that can reproduce the 2-m ramp feature observed in all Arctic deltas. The base model is built from the Arctic Delta Reduced-Complexity Model (ArcDelRCM) based on Delta RCM by Liang et al. (Esurf, 2015) and the advancements to include Arctic settings by Lauzon et al. (GRL, 2019). All the modifications leading to this model (ArcDelRCM.jl) are detailed in a manuscript submitted to the Earth Surface Dynamics journal for review (Chan et al., 2022). The code is written purely in Julia language.
