The Without Development Model is a hydrological model of a river system without any representation of water infrastructure (e.g. storages, weirs), water extraction, water management and operating rules in the system. It includes runoff for headwater catchments, local runoff of residual catchments, flow routing along river reaches, and transmissions losses. The Without development model is derived from the full model of the system, which is calibrated using observed data.

Note: Source software (available from ewater.org.au) is required to view and run the model(s) within.
