One-line model description Matlab toolbox for mapping and measuring river planform changes
Extended model description This toolbox was constructed to help analyze changing river planforms (aerial views). Given a binary mask of a river, tools are provided to efficiently compute

- channel centerline - banklines - channel width (two methods) - centerline direction - centerline curvature

If multiple input mask images contain georeference information, a tool is provided to "stitch" the masks together--before or after analysis. Stitching can be done for both images and vectors of x,y coordinates. The mapping toolbox is required for this functionality.

If multiple masks (realizations) of the river are available, RivMAP includes tools to

- compute centerline migrated areas - compute erosional and accretional areas - identify cutoff areas and quantify cutoff length, chute length, and cutoff area - generate channel belt boundaries and centerline - measure and map changes (in width, migration areas or rates, centerline elongation, accreted/eroded areas) in space and time


planform change, meander migration, river migration, width, centerline, spacetime mapping,
