Growth patterns Modern bayhead deltas have been shown to prograde in a radially symmetric pattern at their onset Growth rates It has been previously hypothesized that progradation slows and ultimately reverses with delta maturity because the area of the delta plain becomes too large to be supported by a constant sediment supply under conditions of constant accommodation creation Avulsions Avulsions constitute the principal mechanism that shift the depocenter within deltas, thereby driving delta evolution over centennial to millennial time scales.
OSL sample preparation and measurement OSL samples were prepared under amber light at Tulane University following standard procedures 50 , OSL age calculation D e data sets were cleaned to remove potential outliers before age modeling see the Supplementary Materials and then treated with a bootstrap minimum age model bootMAM 57 , 58 to obtain the paleodose for each sample.
Avulsion lengths Avulsion lengths in the Mississippi Delta are presented in river kilometers, obtained along the center of river channels using Google Earth. Comparison of mouth bar sand ages estimated using two approaches.
