Science notes: Natural Hydrographs in Regulated Rivers: Conference video now available, plus public comments sought on DISB’s review of BDCP governance, and more!

Natural Hydrographs in Regulated Rivers: Video of the conference now available!  Last month, the Delta Science Program and the UC Davis Center for Aquatic Biology and Aquaculture held a seminar on natural hydrographs in regulated rivers.  The power point presentations were posted in last week’s science news, and now the video of the conference is available from UC Davis:  Click here to view the video of the presentations from UC Davis.

The power points are hereOpening, by Peter Goodwin; A ‘Natural Hydrograph’ for Regulating Rivers, by Professor Geoff Petts, University of Westminster; What do we mean by “natural functional flow” in a regulated and modified system? by Chris Enright, Delta Science Program; Linking Landscape and Hydrologic Regime: clues from history about resilient rivers, by Robin Grossinger, Alison Whipple, and Erin Beller; Herbold presentation; Ecological Response to the Unregulated Spring Flow Regime in California’s Sierra Nevada, by Sarah Yarnell, Carson Jeffres, Ryan Peek,  and Joshua Viers; Examples of Managed Flow Regimes –Possible Models for the Delta?, by Cliff Dahm, University of New Mexico

Public comments sought on the Delta Independent Science Board’s draft memo regarding Chapter 7 of the BDCP.  The memo is posted here and is available for public comment until Feb. 25, 2013. Please send comments to joanne.vinton@deltacouncil.ca.gov

Panel Releases Long-term Operations Biological Opinion Actions Review: The Delta Science Program has posted an article summarizing the results of the review of the coordinated operations of the SWP and CVP.  This year’s review focused on National Marine Fisheries Service (NMFS) Clear Creek RPA actions and the Spring 2012 Delta Operations action.  Click here to read the article.

New Evapotranspiration Maps Provide Crucial Information for Water Managers: The USGS mapped long-term average evapotranspiration rates across the continental United States.  “Since evapotranspiration consumes more than half of the precipitation that happens every year, knowing the evapotranspiration rates in different regions of the country is a solid leap forward in enabling water managers and policy makers to know how much water is available for use in their specific region,” said Bill Werkheiser, associate director for water at the USGS. “Just as importantly,” he added, “this knowledge will help them better plan for the water availability challenges that will occur as our climate changes since transpiration rates vary widely depending on factors such as temperature, humidity, precipitation, soil type, and wind.”  Click here for more from the USGS.
