Overview: Calculates the water volume stored in a given boundary. Best applied to calculate water volume for a given reservoir created in OptiSurface Designer.
by: Tools > Storage Volume...
- Boundary - Select which boundary and surface to base the calculations: Existing or Proposed Surface.
- Top Water Level (m or ft) - Defines the top water level or the elevation of the crest of the reservoir.
- Vertical Calculation Interval (m or ft) - Defines the depth interval which will be used to calculate the Storage Volume Table and the Proposed Storage Depth Map.
- Horizontal Calculation Grid Spacing (m or ft) - Defines how far apart the grid points are horizontally for the calculation. Lowering this to 5m or less will result to more accurate volume calculation.
Below shows a Proposed Topography with a dam created using breaklines. A new boundary called 'C1' and 'C2' was created following the crest of the dam for the calculation of Water Storage Volume.
Resulting Map produces the Proposed Storage Depth Map.
