A specialized utility was added to the Accounting system to allow users to create an alternative mechanism to track water exchanged between accounts. In this approach, the user tracks the exchange with rules that reference specifically named slots on data objects. This utility, called the Data Object Exchange Builder, helps to create this type of exchange by adding slots to a data object and creating supplies on the workspace. The rules must be defined by the user and no support is provided as to what the rules do or how they are written.

More information on this utility can be found in the Data Object Exchange Overview section.

A new method was added to the Diversion Account’s Return Flow Calculation category. The Variable Efficiency Return Flow method computes the returnFlow by multiplying the Diversion by the minimum of the Max Efficiency or the ratio of Depletion Requested to Diversion. For more information on this method, see Variable Efficiency Return Flow.

A new category, Return Flow Route or Split, was added to the Diversion Account. This category has two methods: Simple Lag and Split and Route. The default Simple Lag method (Simple Lag) uses the existing approach where the return flow can be lagged by an integer number of timesteps and no splitting of return flows is allowed. The Split and Route method (Split and Route) allows you to split the return flows to multiple supplies and then route those return flows using linear routing coefficients. Note, the Split and Route method cannot be used by a diversion account in a computational subbasin that performs a water rights allocation using the prior appropriation method and water rights solver.
