Description
This research will test if constructed crevasses obey delta-scaling laws, and examine whether successful or failed crevasses have comparable shapes, and utilize results to develop simple predictive tools. We populated a database of large deltas and added thirteen crevasses in Delta National Wildlife Refuge. Data was obtained using geospatial tools (ArcGIS and Google Earth®) and image analysis, while channel depths were obtained from CPRA. Crevasse geometry exponentially decreases with bifurcation order; hence distance to the mouth bar versus bifurcation order is a reasonable first order estimate. Most crevasses in the Mississippi River Delta appear to obey delta growth laws.
