Flow-MER Fridays: Series 2

Webinar 3: Characterising environmental flows using hydrology

Friday, 12th March 2021: 10.30am – 11:30am

Presenters: Dr. Kris Taniguchi-Quan and Dr. Eric Stein, Southern California Coastal Water Research Project with Gavin Pryde, Commonwealth Environmental Water Holder

The talk will provide an overview of the functional flows approach for the establishment of environmental flow requirements aimed at protecting multiple ecological endpoints and evaluating catchment conditions.

It will further discuss the integration of this approach in the Basin-wide modelling being undertaken in the Flow-MER project.

Gavin Pryde from the Commonwealth Environmental Water Holder will talk about how environmental water requirements based on some of these concepts are used by water managers to inform planning and delivery.

Gavin Pryde

Gavin has worked in a range of natural resource and water management areas since leaving the University of New England in 1991. During this time, he spent 16 years with the NSW government undertaking a range of waterway restoration programs before moving into the water management space. He has spent the last 12 years with the MDBA and Commonwealth Environmental Water Holder working on an number of water management program areas.
