Many regulated river systems support several resource assessment schemes to share the available resource (water) among users. In Source, a resource assessment system:
- is associated with only one scenario in a project, whereas a scenario may be associated with one or more resource assessment systems;
- can only have one owner, but any given owner or water user may be affected by more than one system; and
- supports multiple account types.
There are three types of resource assessment supported in Source:
- Annual accounting - This is a custom assessment method for regulated water;
- Continuous accounting - This replicates the resource assessment system used in the Gwydir and Namoi in NSW; and
- Continuous sharing - In this system, the behaviour of a water user has as little effect as possible on other water users within that system.
You can also configure the following attributes that make up the above three systems:
- Accounts - Water users within a model are linked to accounts, that allow them to request resources;
- Usage limits - Limits the amount of resource that can be delivered to water users;
- Account type triggers - A trigger initiates or cancels certain actions for an account type; examples include dates and water levels; and
- Off allocation systems.
