Summary Contact Technical specs In/Output Process Testing Other Component info Also known as Model type Tool Model part of larger framework Incorporated models or components: Spatial dimensions 2D Spatial extent Continental Model domain Terrestrial 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 Keywords: planform change, meander migration, river migration, width, centerline, spacetime mapping, Name Jon Schwenk Type of contact Model developer Institute / Organization University of Minnesota Postal address 1 Postal address 2 Town / City Minneapolis Postal code 55414 State Minnesota Country United States Email address jonschwenk@gmail.com Phone Fax Supported platforms Linux, Mac OS, Windows Other platform Programming language Matlab Other program language Code optimized Single Processor, Multiple Processors Multiple processors implemented Nr of distributed processors Nr of shared processors Start year development 2015 Does model development still take place? No If above answer is no, provide end year model development Code development status As is, no updates are provided When did you indicate the 'code development status'? 2020 Model availability As code Source code availability (Or provide future intension) Through web repository Source web address https://www.mathworks.com/matlabcentral/fileexchange/58264-rivmap-river-morphodynamics-from-analysis-of-planforms Source csdms web address Program license type GPL v3 Program license type other Memory requirements Typical run time Describe input parameters Binary channel mask imagery (georeferencing optional). Imagery through time can be input to assess planform changes. Input format Other input format any binary image loadable in Matlab Describe output parameters For a single image: centerlines, widths, channel direction, curvatures For multiple images: (centerline) migration areas, erosion and accretion areas, cutoffs, cutoff statistics, channel belt boundaries, grid generation to map spatial changes, spacetime maps of changes in planform variables Output format Other output format Matlab structure variable(s) Pre-processing software needed?
