Introduction

This auxiliary material contains a text file with a table and two animations.

1. 2011gl047630-txts01.doc
Text S1. Details on shoreline transport and diffusivity and mass balance 
approach to delta lobe growth, with Table S1.

Table S1. Location, sources of imagery, and sources of wave data used to 
generate Figure 1.

2. 2011gl047630-ms01.mov
Animation S1. Side-by side animations of simulated delta growth (for same time 
steps) for results shown in Figure 3. Simulations used identical parameters 
except for wave climate variables.
Left side: Symmetrical delta with A = 0.5, U = 0.4.
Right side: Asymmetrical delta with A = 0.8, U = 0.3.

3. 2011gl047630-ms02.mov
Animation S2. Side-by side animations of simulated delta growth (for same time 
steps) for results shown in Figure 3. Simulations used identical parameters 
except for wave climate variables.
Left side: Symmetrical delta with A = 0.5, U = 0.4.
Right side: Asymmetrical delta with A = 0.7, U = 0.4.
