This category allows the RiverWare simulation to automate the creation of the Cumulative Storage Value Table. This category is only visible if Cumulative Storage Value Table is selected in the Future Value category.

If this method is selected, no automation will be performed and the user must enter the data into the Cumulative Storage Value Table.

If this method is selected, the Marginal Storage Value table will be used as the source for the generation of the Cumulative Storage Value Table. This is the only calculation associated with this method. There are no slots associated specifically with this method.

This method uses information from the simulation slot Marginal Storage Value Table to generate a cumulative storage value table. The cumulative storage value can be thought of as the summation of the marginal storage values from a storage of 0 to the current storage. Therefore, the automation method finds the same midpoint values used by the simulation Future Value Calc method, and uses those points in the table.

If only one value exists in the Marginal Storage Value Table, then only two entries will exist in the Cumulative Storage Value Table. The two entries will be 0, and midway between the value in the Marginal Storage Value Table, and the maximum value set on the Storage slot. If more than one value exists, three or more points will result. Following are sample Table 24.1 and Table 24.2 are examples of a Marginal Value Table and the resulting Cumulative Storage Value Table. Figure 24.1 is a sample graph of the Cumulative Storage Value data.
