...

Account Balance Pre Exit: Account balance in pre exit Phase

Total Account Balance: Total amount of account balance from all accounts. Only available at system level.

Available Water:  Sum of available water in allocation account balance and carry over account balance. Each account has two account balance, one is to record allocation balance, the other is to record allocated carryover water balance which is carried over from last water season. Not all the water in these two account balance are available for use, some water can be reserved for special purpose, such as spilling. Only available component can be used by water user. Post post triggers phase but before two carryover triggers

...

Carryover Allocated: This is the water carried over from last water year and is allocated to water user in current new water year.

Effective Allocation = min (maximum effective allocation, (carryover start of water year + total allocation water year - spill reduction water year) / Entitlementnumber of shares)

Forfeit End of Water Year:

...

Max WDD: Maximum amount of without debit diversion. Non-debit accounting are designed for particular river systems (Murray, Murrumbidgee, Babubula and Upper Namoi) in New South Wales. Different river system has different rules for water diversion under no- debit accounting. For more details, please go to annual accounting SRG.

Number of Shares: A  A right to take/use/extract/have water delivered over a water year.

...

Account Balance Spill  Reduction: not sure this one? also 0??

Account Type Spill Volume: This is a user defined spill volume for an account type. Modeler can specify spill volume from Carryover tab under account type level in annual accounting system.

Total Account Spill reduction PriorityReduction: Priority order Sum of spill deducted from a account type. An account type with priority of "1" will have spill deducted before an account type with priority of "2". Only available at account type levelSpill reduction water year: Accumulative spill reduction from reduction from all accounts within the RAS in the current time step, sourced from RAS Post phase after post triggers (Post Post trigger) but before Sum of spill reduction from all accounts within the RAS in the current time step, sourced from RAS Post phase after post triggers (Post Post trigger). Only available at system level.

Total  Account Spill Reduction Water Year:  Total amount of spill reduction from all accounts form start of water year to current time step. It keeps track of water is lost when the dam spills over the water year.

Spillable water: Any carryover or allocations above water share volume. It keeps track of any water that can be lost if the dam spills. Spillable water can not be used or traded until it is recognized as low risk of spill and spillable water will then become available. Post post triggers phase but before two carryover triggers

There are two different rules for calculation of Spillable water:

...

Only available at system level.

Spill reduction Priority: Priority order of spill deducted from a account type. An account type with priority of "1" will have spill deducted before an account type with priority of "2". Only available at account type level

Spill reduction water year: Accumulative spill reduction from start of water year to current time step. It keeps track of water is lost when the dam spills over the water year.

Spillable water: Any carryover or allocations above water share volume. It keeps track of any water that can be lost if the dam spills. Spillable water can not be used or traded until it is recognized as low risk of spill and spillable water will then become available. Post post triggers phase but before two carryover triggers

There are two different rules for calculation of Spillable water:

  • Total water - 100%: The calculation is made based on the state of the Water Available While Spillable checkbox:
    • If enabled, Spillable water = max(0, Total allocation water year + Carryover start of water year − 100% entitlement − Total spill reduction water year − Total usage from carryover water year); or
    • If disabled, Spillable water = max(0, Total allocation water year + Carryover start of water year − 100% entitlement − Total spill reduction water year). In this case, spillable water increases with allocation.
  • Carryover - Use: In this case, Spillable water = Carryover start of water year − Total usage carryover water year − Total spill reduction water year.

Total Spillable Water: Total amount of spillable water from all spillable accounts. Only available at system level.

Spillable Trigger: This recorder is to keep track of whether an account type is spillable or not. A value of "1" represents it is spillable, otherwise a value of "o" means it is not spillable. Only available at account type level.

...

Total Account Adjustment Water Year: Accumulative accounts adjustment from start of water year to current time step.  

Total Allocation Water Account Adjustment: Sum of balance in all accounts' Account Balance components within the RAS in the current time step, sourced from RAS Post phase after post triggers (Post Post trigger).

Total Allocation Water Year: Total amount of water that has been allocated to an account in a water year. The allocation is made again entitlements throughout a water year.

Total Commitment This recorder is to keep track of total amount of water that can be used from start of water year to current time step. It includes the water that has already been used.

  •        For spillable water accounts:

                         Total Commitment Commitment = Minimum [(Total allocation water year + Carryover Start of Water Year - Spill Reduction Water Year – Adjustments due to triggers), Usage Cap if any]

  •       For non-spillable water accounts:

                         Total Commitment Commitment = Minimum {[ Minimum (Total allocation water year + Carryover Start of Water Year, Max Effective Allocation Water Year) – Adjustments due to triggers], Usage Cap if any}

  •       For non debit accounts
                  Total Commitment Commitment = Minimum (Total allocation water year + Carryover Start of Water Year– Adjustments due to triggers, modified effective allocation water year)

Total Usage Carryover Water Year: Accumulative usage from carryover accounts from start of water year to current time step. It keeps track of usage of carryover water over the water year

Total Usage From All Paths Water Year: Usage of water from all different sources, including normal allocation, carryover water, off allocation water and water that has been lost on the way to extraction point.

            Total Usage From All Paths Water Year = Total Usage Water Year + Off Allocation Usage Water Year + Total Distribution Loss Water Year

Total Usage Water YearAccumulative usage from both allocation accounts and carryover accounts from start of water year to current time step. Without debit water repayment is deducted from allocation accounts and it is also included in total usage water year.

Total Usage: This is usage of water from both allocation accounts and carryover accounts per each time step. Only available at system level. 

Total Water accounts: Sum of remaining water from all accounts from start of water year to current time step. Only available at account types, account hosts and system level. Post post trigger phase but before two carryover triggers.

...

Total Water Accounts Post Trigger: Total water accounts in post post trigger phase

Transferred Water Use: Water usage that has been transferred to different account/account type.

Truncated Total Transferred Water Use: Total amount of transferred water use from all accounts. Only available at system level.

Truncated CarryOver: carryover that has been truncated due to total amount of allocation and carryover goes beyond the maximum effective allocation cap

                  Truncated carryover =min ( carryover balance,  max ( 0, allocation + carryover - maximum effective allocation cap) )

Total Truncated Carryover: Total amount of truncated Carryover from all accounts. Only available at system level

WDD Repaid: Accumulative repayment of without debit water usage. This recorder is to keep track of repayment of without debit water usage.This repayment is based on allocation level, adjustment to account does not affect it.

WDD Usage: Accumulative usage of without debit diversion water. It keeps track of usage of without debit water over the water year.

Volume Druing Assessment: Active volume of water stored in storages, can be allocated to water users. Dead storage is not included.

Available Resources: Total available water resources that can be allocated to water users. It can include active storage volume, forecast inflows, other resources that will be transferred into and so on. for more details, please go to annual accounting SRG.

Commitments: This is the part of resources that is needed to be set aside for other purpose, such as reserve for environmental flow or needs to be supplied to other water users. It should be subtracted from available resources.

Forecast Inflows: This is the forecast inflows that could be added to available resources for allocation reassessment. For unregulated inflow which did not flow into any storage, a recession factor is usually assigned to it before it being added to available resources.

Other Resources: This is to consider other available resources, such as transferred water, which could be added to available resources reassessment.

Carryover Total Reassessment: looks like the same as carryover start of water year??

Spill Volumes: The amount of annual accounting system spill volumes based on user defined function in the "Spill Volume" field under the RAS's "Configuration" tab. Should it be spill volume from accounts rather than decided by the function??

Emptied On Spill: Not sure??? It is different from Total Emptied, one year lag and double the value of spill volume.??? a bug??

Total Emptied: Total emptied on spill from carryover. This recorder keeps track of spill reduction that are based on method of "Emptied on Spill or Pre-Release". rename to Total emptied on spill??

Available Storage Volume: This is the storage volume that are available to be allocated to water users. Inactive volume in storage (dead storage volume) and evaporation are not included. 

Evaporation to End of Season: Total evaporation (mm) from current time step to end of water year. ( Evaporation in RAS "Configuration" tab, not the one on storage node)

Inflow to End of Season: Total inflow from current time step to end of water year (Inflow in RAS  "Configuration" tab, not the one on storage node)

Net Evaporation Volume to End of Season: Total evaporation volume (ML) from current time step to end of water year.( Evaporation in RAS "Configuration" tab, not the one on storage node)

Volume Druing Assessment: total storage active volume ( before adding inflow or subtracting evaporation ) that can be used for resource reassessment . Storage inactive volume is not included.
