Underlying data for "Mechanisms of Dune Growth and Decay in Rivers" submitted to Geophysical Research Letters

Description: This data set includes information needed to understand, evaluate, and build upon the manuscript "Mechanisms of Dune Growth and Decay in Rivers". The included bathymetric surveys show how dunes grow and decay through the 2012 flood in the Fraser river. Dunes grow as flood levels increase by amalgamating with smaller dunes once a flow threshold is passed. After amalgamation, changes to individual dunes are subtler and likely driven by changes to the flow field. As the flood recedes, smaller features appear on the backs of big dunes, reworking and flattening the bed. Small dunes on the backs of big dunes may be a signature of dune decay. Analysis of gauge data from Water Survey of Canada and the Canadian Hydrographic Survey, included here, show that growth by amalgamation and decay by secondary features occur at a common flow threshold. The results can be used to improve how we model floods and interpret fossilized dunes in the rock record on Earth and other planetary surfaces.
