| Item | Description |
|---|---|
| Name | Name of the account. |
| Account host | Node that the account is associated with. |
| Account type | Type of account. This is configured under the hierarchical item Account Type. |
| Unit shares | |
| Initial balance | The initial account balance. If you are going to use the initial account function, you need to ensure that there is sufficient water in storages to cover the total initial balances as well as the required reserves and TOL balance. If the initial balances are set too high a warning message will be generated and the results may not follow the required logic. |

Adding accounts
Click Add Account To add an account in the table, click Add Account below the Accounts table to open the Add New Account dialog (shown in Figure 3) and add an account in the table. The number of hosts available in a scenario will determine the number of accounts in an account type. Hosts in a scenario may consist of water users, bulk licensing node nodes and the environmental demand node.

The Allocation tab shows how resources are distributed, along with the proportion that is carried over (as shown in Figure 4). This view changes with how the Account type has been configured, in particular the Method to apply for this account type in ARA table parameter. Figure 4 shows how the Rural column changes with the varying parameter. Additionally, the ARA table will display as the variations shown in Table 3.

| Percent (with linked volume) | The Account Type column can be edited directly on the table. The Resource column is calculated automatically based on the percentage . Unclear |
| Function | The Resource in the table will calculate automatically based on the function that was set at the Account or Account Type level. |
| Monthly-varying | You need to set the date for resource calculations. Click the number below the Account Type name, the monthly varying window will display as in Figure ??. You can set the resource of each monthly manually or by import or export data using the corresponding buttons. If interpolate is chosen for calculation method, the Resource of the first column will calculated automatically based on current and next month values. More details about interpolate can be found in SRG. If Threshold is chosen, Resource of the first column will get value automatically form current month. |
| Percent (with function) | Function below the account type is editable because functions of this method cannot be set at a lower level. |
| Volumetric | the account type has a unit of (ML) and the rural column can be editable by typing number directly to the table. Then the value in Resourcecolumn is equal to that in Account Type column. |
Trigger Priority
Figure 5 shows the priority of the trigger. They are separated into two types based on Timestep Beginning and Timestep End. You can re-order the triggers to set the priority.

Account Type
An annual accounting system may contain several account types. Each account type can also include many accounts. As shown in Figure 1, right click on the annual accounting system and choose Add Account Type. The resulting window is shown in Figure 2.
In the Account Type level, you can use the:
- Configuration tab to configure the account type (shown in Figure 6);
- Accounts tab to view a summary of all accounts in the account type; and
- Non-Debit Accounts tab to view and configure all non-debit accounts in the account type.
The next section describes each of these tabs.
Configuring an account type
The parameters that must be defined are described in Table 14.

| Item | Description |
|---|---|
| Debit Type | Determines how water is deducted from all accounts associated with this continuous accounting system; based on either order or extractions. |
| Priority | A higher priority translates to resources being allocated prior to a lower priority user. |
| Minimum Balance | If a minimum balance is defined, then order or extractions will not be allowed if it will cause the balance to drop below the minimum specified. If choosing Unrestricted, also specify the Minimum Volume. |
| Maximum Balance | Defines the maximum volume of water which can be held in an account. If an allocation results in this limit being exceeded, then the excess amount is redistributed to other accounts. |
| Allocation Calculation | The default is Available Resource Allocation Table, which opens the ARA table. The options available for this are shown in Table 2. Choose Function to determine an account type's allocation using this method. This function may reference a wide range of variables available in the model, including allocations to other account types and resource assessment system. The Allow Decrease checkbox controls whether or not an account’s allocation can go down within the water year. |

These are explained in further detail next.
Adding an account for an account type
Here, you can configure Number of Shares, the Initial Account Balance and Previous Usage. To link the account to a host, choose the water user under Associated Account Host. The associated account lists all the water user nodes in the project. Once these have been configured, you will notice that the value configured for the Number of Shares relates to the Demand distribution item of the water user node (

Adding a trigger to an account type
Triggers are used to initiate or cancel certain actions for an account and can be added at any level in annual accounting. To add a trigger, right click the account and choose Add trigger. In the resulting right side panel (as shown in Figure
38), you must configure the Trigger and Execution options (as shown in Figure
38) and the resulting Action Configuration panel below will change depending on what is chosen above. You can also trigger actions using a function. This is accomplished by choosing Function as the Trigger option. The format of a function should be like this: “IF A>B, 1, 0”, where “1” indicates the action will occur and “0” means the action will not happen. An account can have several triggers, each can be designed to initiate a particular action. You can rename or delete a trigger by right clicking the trigger and choosing the appropriate contextual menu option. After triggers are configured, you can prioritise them
usingusing the Trigger Priority tab (Figure 5).

Adding a usage limit
- Rightto an account type
Right click the account or account type and choose Add usage limit. The GUI is similar for that in Continuous Accounting (here). You can limit water usage for all accounts by absolute volume or per-unit-share for moving water year or movable time window. An account can have several usage limits, each can be designed to initiate a particular limit. Just like triggers, you can rename or delete usage limits.
Configuring an Account Type
When account, trigger and water usage limit are all set up, you can go back to account type to configure and see summary information of all added accounts.
Click Account Type on the left hand panel, and make sure the configuration tab is selected on the right (Figure 2), set debit type, priority, minimum and maximum balance, minimum and maximum volume. If they are non-debit accounts, you need to tick the box Enable non-debit accounts, and then the availability threshold and repayment threshold become editable.
For allocation calculation method, there are two options from the allocation calculation drop down menu (Figure 2). One is as a function, where you can determine an account type’s allocation. The other is by using an available resource allocation table (ARA table). This function may reference a wide range of variables available in the model, including allocations to other account types and resource assessment systems. If an ARA table is chosen (Figure 7), configuration options will display for you to set detailed information.
Figure 7 Configuring Allocation Calculation Model
There are five methods can be chosen form the drop-down menu of method to apply for this account type in ARA table (Figure 7):
Function You set the function at this level.
Monthly varying You can set the calculation method as either interpolate or threshold.
Percent (with Function) This is similar to percent (with linked volume), difference exists at the annual accounting level allocation page which is discussed somewhere.
Percent (with linked volume) The default option for method to apply for this account type in ARA table. You can set Announced Increment, Maximum Announced Percent and Shares. If Use Shares from Accounts is ticked, Shares will get value automatically from account shares which is set at the account (rather than the account type) level.
Volumetric. You will need to set the volume at the annual accounting level allocation page which is discussed somewhere.
Accounts summary at Account Type Level
Clicking on the Accounts tab beside configuration at the top of the right hand panel (Figure 7), will show all the accounts created under this Account type.
You can also add an account simply by click the Add Account button below the list, or delete an account by selecting the account that to be deleted and clicking the Delete Account button. The Unit Shares and Initial Balance values are transferred automatically from the account but can also be edited here (Figure 7b).
