The methods in this category specify how the diversion account calculates the Initial Request in the water rights allocation. These methods are valid only if the account has a water right as specified by the Priority Right method.

No initial request is necessary or specified. This is the default.

This method allows the user to specify the initial appropriation request for use in a prioritized water rights allocation.

The initial request is calculated from annual values.

Annual requests are disaggregated to this model’s timestep according to the values specified in the computational subbasin. This method is executed from the computational subbasin at the beginning of the run. See Account Initial Request in Objects and Methods for additional information.

The initial request is assumed to be unbounded, so that the resulting Appropriation Request slot value is the maximum amount permitted by all other constraints, such as the amount of water available in the supply chain, physical constraints such as diversion structure capacity, and legal constraints such as minimum bypass, and not shorting downstream senior accounts, unlike the calculations of Appropriation Request with all other method selections. The Initial Request and Shortage slots are not made available when this method is selected. When this method is selected, the permitted appropriation is left in the Appropriation Request slot, but no appropriation is made.
