Table 1. Continuous Accounting, Configuration parameters
Item Name | Description | ||
|---|---|---|---|
Owner | Volume of water available for the system based on the ownership share of any assigned storages. Ignore for ownership off case. | ||
Debit Type | Determines how water is deducted from all accounts associated with this continuous accounting system; based on either order or extractions. | ||
| Timesteps per Assessment | Defines number of time-steps between assessments. | ||
Start of Water Year | Day-month that the water year starts for the continuous accounting system. Relevant for high security accounts as they are treated as annual accounts. The water year is also applicable to usage limits for the general security accounts. | ||
No further resource assessments from this date | Day-month after which no further resource assessments should be conducted. | Timesteps per Assessment | Defines number of time-steps between assessments. |
Assigned Storages Table | Lists all storage scenarios. These can be included as resources for the Resource Assessment System if required. | ||
Account Type
Lists the account types available by default in a continuous accounting system.
Allocation Priority
Determines the order in which account types will be credited during a resource allocation.
When you add a continuous accounting system, the following account types are automatically loaded:
- Storage Loss Reserve - define the reserve required for evaporation and seepage losses from storage;
- High Security Group 1 - define the reserve required for high security users. Also allows you to define accounts which relate to this reserve and the method for allocating water to these accounts;
- Trigger Write-Off
- High Security Group 2 - same as for High Security Group 1 but relates to a separate, lower priority group of high security users;
- Trigger Write-Off
- Generic System Share 1 - used to allocate water to another Resource assessment system; and
- General Security 1 - allows you to define accounting rules and shares for general security accounts;
- Usage Limit One Year; and
- Usage Limit Three Years.

| Note: IQQM includes a number of inbuilt triggers which are not replicated in Source. For this reason, the Timesteps per assessment parameter may need to be set to 1. Additionally, to replicate IQQM, the TOL Share parameter on the high security account type should be zero. |

In the Resource Assessment Explorer, when you choose to the Function Editor dialog allows you to link two resource assessment systems using the Time of Evaluation tab. Normally, fields in the function editor are lagged by a time-step (that is, they get their value from the last time-step to use in the current time-step). Enabling the During Resource Assessment checkbox results in the resource assessment system linked parameters being executed within the current time-step. As long as the resource assessment system appears above another resource assessment system in the hierarchical list, the values will be up-to-date in the time-step. Conversely, if one resource assessment system appears below a linked resource assessment system, its values will be lagged by a time-step.
