Why we did it

Environmental water managers, like the Commonweath and Victorian Environmental Water Holders are tasked with delivering scarce water resources to the environment. These organisations set environmental watering objectives, which involve delivering water at specific volumes, durations, and at specific times, to meet the needs of species and environmental processes.

Assessing the success of environmental water delivery in meeting objectives has historically been a complex task, requiring extensive consultantation.

The Victorian Environmental Water Holder approached Truii to develop a reporting tool that would make save them time and allow them to communicate the impacts of their environmental watering program.

What we delivered

Truii created eFlow Projector, a web-based reporting application for environmental water managers to assess the performance of environmental watering objectives. It allows them to better plan upcoming watering strategies and to report on their outcomes.

eFlow Projector reports the success (including partial success) of watering events, the success of the individual components of events, and the relative contribution of delivered water to those events. It can be applied anywhere that has daily streamflow data.

The web app uses Truii’s core API to load spatial data, render visualisations and manage users.

eFlow Projector has evolved significantly since the original bespoke client app we created for the Victorian Environmental Water Holder. It has since been developed further and is available to any organisation via subscription.

Key features

• Reports partial success of environmental watering objectives both annually and long-term.
  Dynamic visual reporting interface.
• Considers different prevailing climatic conditions (the water requirements during drought year are often different to those in a wet year).
• Allows the prevailing climatic condition to change throughout the year.
• Quantifies the relative contribution of environmental water delivery to the success of an environmental watering event.
