For a single cell, the formula for the volume is:įor example, a particular cell has an initial z-value of 235 and a cell size of 10 meters.

Edge-connected areas identifiedįirst, from the upper-right corner, a sequential value is given to each unique edge-connected area of cut, fill, or no change.ĭifferent types of connectivity are demonstrated in the following graphic: Cut/fill regions Volume calculationįor each of the cut/fill regions, the volume is calculated. The output raster retains several properties of the change in itsĪttribute table. The third graphic shows how the Cut Fill tool identifies the areas where material has been removed (cut) and where it has been gained (filled): Cut/fill erosion and deposition Calculations The second graphic shows the surface after a period of time where erosional and depositional forces have acted on it: After surface profile The first graphic shows the surface in its original state: Before surface profile Usage cut(x, ) S3 method for default cut(x, breaks, labels NULL, include.lowest FALSE, right TRUE, dig. The leftmost interval corresponds to level one, the next leftmost to level two and so on. cut divides the range of x into intervals and codes the values in x according to which interval they fall.

The following graphics show a side profile of one of the cross-sections in the surface that has experienced changes where material has been removed from some areas and added to others. cut: Convert Numeric to Factor Description.

Using river morphology as an example to track the amount and location of erosion and deposition in a river valley, a series of cross sections need to be taken through the valley and surveyed on a regular basis to identify regions of sediment erosion and deposition. See the Illustration of the tool documentation for an example. The determinant is the attribute table of the output raster and considers positive volume to be where material was cut (removed) and negative volume where material was filled (added). When the Cut Fill tool is executed, by default, a specialized renderer is applied to it that highlights the locations of cut and of fill.

Identify regions of sediment erosion and deposition in a river valley.With the Cut Fill tool, you can do the following: By taking surfaces of a given location at two different time periods, it identifies regions of surface material removal, surface material addition, and areas where the surface has not changed. The Cut Fill tool summarizes the areas and volumes of change from a cut-and-fill operation. A cut-and-fill operation is a procedure in which the elevation of a landform surface is modified by the removal or addition of surface material.
