Formula that calculates area between sub-increments
Formula that calculates area between sub-increments
Formula that calculates cross section area between each sub-increment and the previous sub-increment. de Winter, N. J. (2017) doi:10.5194/gmd-2017-137
Oyster_subincr_area(IncG, subincr_matrix, Xstep)
Arguments
IncG: Matrix of X- and Y-coordinates of all interpolated sub-increments
subincr_matrix: Data frame that contains characteristics of every sub-increment
Xstep: Step value in X-direction for the interpolation of sub-increments
Details
Areas between sub-increments are calculated by averaging the difference in Y-values between sub-increments and multiplying them with the step in X-values (dx)
Returns
subincr_matrix: Revised version of the "incr_matrix" data frame that contains cross section area recalculated for every sub-increment
