The challenge
There are around 400 environmental watering requirements to keep track of each year across Victoria. It is the job of the Victorian Environmental Water Holder to plan, implement and report the success of environmental water delivery.
Traditionally, assessing the performance of water delivery required complex desktop studies, which delivered binary success/fail results. However, the actual success of the environmental watering is more nuanced, in that a watering event that partially meets the flow requirements can still provide benefits and should not be considered a failure.
The Victorian Environmental Water Holder needed a tool to help them capture the nuances of water delivery and that would make their annual delivery reporting easier.
