Specifies points on Depletion Curves for impermeable and permeable surfaces within a design study area:
These curves define the relationship between the area that remains covered with snow and the depth of the snowpack. Each curve is defined by 10 equal increments of relative depth ratio between 0 and 0.9. (The relative depth ratio is the ratio of an area's current snow depth to the depth at which there is 100% area coverage.)
Enter values in the data grid provided for the fraction of each area that remains covered with snow at each specified relative depth ratio. Valid numbers must be between 0 and 1 and increase with increasing depth ratio.
When all values are equal to 1, it means that there is no area depletion. This is the default for new projects.
