Account Adjustment: Sum of Account adjustment due to adjustment triggers (exclude spill adjustment). Post Exit Phase. An example is to use adjustment trigger to subtract evaporation loss from account.

Account Balance

Account Balance = account balance from end of previous time step + increased allocation - usage -adjustment by triggers

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.

     If "Water Available While Spillable" is enabled, 

     Available water = Account balance + Carryover Water; which means all water in these two account balance are available for use

    Otherwise, 

    Available water = Account balance + Carryover Water - spillable Water; which means some water (spillable water component) are reserved and not available for use

Available Water in Account Balance: This is available water that can be used in allocation account balance.

Available Water in Carryover: This is available water that can be used in carryover account balance (exclude non available spillable water). 

Carryover

carryover = carryover balance from end of previous time step - usage - spill reduction - adjustment by triggers

Carryover Allocated: This is the water carried over from last water year and is allocated to an account in new water year. For the total amount of water carried over from last water year,  how much can be allocated is defined by modeller in "Carryover" column in Available Resource Versus Allocation ( ARA ) table.

Carryover Next Year Trigger Total: Water that can be carried over from account balance to next water year due to carry over trigger at the end of current water year

Carryover Scalar: This is the parameter defined by modeller in "Carryover" column in ARA table. It represents allocation percentage of carryover water.

Carryover Start of Water Year: Total amount of water carried over from last water year to start of a new water year

Change in Allocation: Difference in allocation volume for current time step compared to last time step. Allocation level may change after each reassessment.

Change in Allocation Percent : Difference in allocation percentage for current time step compared to last time step. 

Change in Allocation Percent = ( Change in Allocation / Entitlement )*100%

Effective Allocation: Total percentage of allocated carry over water (exclude spill) and allocation

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

Max WDD: Maximum amount of without debit diversion

Number of Shares: Annual volumteric entitlements

Off Allocation Usage Today: Off allocation water used for current time step

Off Allocation Usage Water Year: Accumulative off allocation water usage from start of water year to current time step

Order/Use Debit: Water debited from accounts for current time-step

Spill Reduction: Spill deducted from accounts for current time step

Spill reduction water year: Accumulative spill reduction from start of water year to current time step

Spillable water: Water in accounts that can be deducted for spill

Spillable water is calculated using one of two methods:

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

Total Allocation Water Year: 

Total Commitment:  Only available at account type, account host and system level.

Total Usage Carryover Water Year: Accumulative usage from carryover accounts from start of water year to current time step

Total Usage From All Paths Water Year: Accumulative usage from both allocation accounts and carryover accounts from start of water year to current time step

Total Usage Water Year: Same as total usage from all paths water year ???

Total Water accounts: Sum of remaining water from all accounts from start of water year to current time step

Transferred Water Use: Water usage that has been transferred to different account/account type due to transfer trigger

Truncated CarryOver: Truncated carryover water due to maximum effective allocation cap
