The Peace-Athabasca Delta (PAD) in Alberta, Canada is among the largest inland deltas in the world. Within the PAD, a new subdelta began forming in 1982 when the Embarras River avulsed into Mamawi Creek. Because the resulting Mamawi Creek Delta formed so recently, satellite imagery and field data constrain its entire development. In this work, we examine the 40-year progradation of Mamawi Creek Delta with morphodynamic modeling informed by field data, and satellite remote sensing. First, we use field observations of flow, sediment characteristics and Mamawi Lake bathymetry to construct a site-specific model of Mamawi Creek Delta using Delft3D. Then, to assess how well the model captures the observed progradation of this delta, we iteratively compare predicted delta growth against that measured from optical Landsat images. Based on these comparisons, we adjust key model parameters to create a more realistic morphodynamic simulation of Mamawi Creek Delta and better understand growth patterns.
