README/Reference file for data associated with the manuscript 'Predicting wave-induced sediment resuspension at the perimeter of lakes,' in review at Water Resources Research Data description for: 'STWAVE_ModelOutput_NodeTables.mat' Author: Derek Roberts, UC Davis, dcroberts@ucdavis.edu November 2018 This file describes the production of the data provided in the files: 'STWAVE_ModelOutput_NodeTables.mat' and 'STWAVE_ModelGrid_50m.mat' for the manuscript 'Predicting wave-induced sediment resuspension at the perimeter of lakes,' in review at Water Resources Research, herein referred to as "the main text." Data contact: Derek Roberts, UC Davis Tahoe Environmental Research Center (TERC), dcroberts@ucdavis.edu %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% 'STWAVE_ModelOutput_NodeTables.mat' The steady-state spectral wind-wave model, STWAVE, was run following the setup described in the main-text. This file contains node-specific tables of discrete model output (wave height and bed-shear stress) at 756 wind speed/direction combinations (0-20 m/s by 1 m/s; 10 to 360 deg by 10 deg) at all grid nodes where the lake depth is less than or equal to 5 m (a generalization of the nearshore area; see STWAVE_ModelGrid_50m.mat for details on lake bathymetry). The data are stored in a MATLAB structure "stwave." Sub-variables within this structure are as follows: stwave.nodes: two-column array where each row represents a discrete model node; column 1 is the row index (y) and column 2 is the column index (x) stwave.nodedepths: vector array with row indeces corresponding the indeces of the nodes in stwave.nodes. stwave.spds: discrete set of wind speeds for which stwave model output were tabulated. Units are meters/second. stwave.dirs: discrete set of wind diections for which stwave model output were tabulated. Degrees clockwise from north FROM which the wind is blowing (0 is represented as 360). stwave.H: cell-array of tables of wave height values (in meters) where: -the cell index corresponds to the node index from the row in stwave.nodes -the 36x21 array within each cell includes wave heights (m) for wind speed and direction combinations corresponding to indeces of the wind speed and direction values in stwave.spds and stwave.dirs respectively. stwave.SS: cell-array of tables of bed-shear stress values (in Pascals) where: -the cell index corresponds to the node index from the row in stwave.nodes -the 36x21 array within each cell includes bed-shear values (Pa) for wind speed and direction combinations corresponding to indeces of the wind speed and direction values in stwave.spds and stwave.dirs respectively. stwave.nodedepths: Depth (meters) of the nodes specified in stwave.nodes; row indeces correspond to rows in stwave.nodes. Example: stwave.SS{6}(3,6) is the bed-shear stress value at the node location specified by stwave.nodes(6) and at a wind speed of 2 m/s and direction of 60 deg because stwave.spds(3) = 2 m/s and stwave.dirs(6) = 60 deg. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% 'STWAVE_ModelGrid_50m.mat' Numeric array of Lake Tahoe depths (meters) at 50-meter evenly spaced nodes. See main-text for description of data collection and preparation. Row and column indeces indicate relative node spacing in the south-to-north and west-to-east directions respectively. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% 'STWAVE_NearshoreStationNodes.txt' Grid nodes representing nearshore station locations (see main-text) on the discrete grid domain 'STWAVE_ModelGrid_50m.mat.'
