WWA WebinarsWWA Webinars

In 2012, WWA began offering a series of occasional webinars to present research by WWA team members, as well as work by others relevant to WWA's stakeholders. Below are the upcoming webinars, and the links to the presentations and audio and/or video from past webinars.

Upcoming Webinars

Exploring the Use of Multiobjective Evolutionary Algorithms (MOEAs) for Long-term Planning by Front Range, Colorado Water Managers
Rebecca Smith
Western Water Assessment and Civil and Environmental Engineering, University of Colorado Boulder

Many promising tools and methods developed in water resources systems analysis research have seen little uptake outside of academia. This may be due to a lack of effective communication about the research to water managers, or it may be because the tools are not ultimately useful or usable in practice. Current predominant research frameworks do not provide insight into these issues or facilitate the incorporation of industry needs into research agendas. We developed a structured process to address this disconnect called the Participatory Framework for Assessment and Improvement of Tools (ParFAIT). We applied ParFAIT specifically to Multiobjective Evolutionary Algorithm (MOEA)-assisted optimization. MOEAs are bottom-up decision support tools that researchers have proven can increase learning and improve outcomes in academic water resources planning studies, but which have seen very limited uptake in real-world water management. This presentation describes our application of ParFAIT during which we worked with Front Range, Colorado, water utilities to co-produce an MOEA testbed, evaluated the tool’s potential to enhance utilities’ long term planning processes, and applied statistical methods to advance the usefulness of MOEA results.

WWA/NIDIS Webinar: Decision Making in the Face of Drought by Western Range Livestock Producers
William R. Travis and Trisha Shrum
Western Water Assessment and Earth Lab University of Colorado Boulder

Ranchers make a large number of time-sensitive decisions each year and can vary their choices in the face of drought throughout the production cycle. Ranchers’ drought decisions may also be affected by USDA’s new Pasture Rangeland and Forest insurance program, a rainfall-index product meant to compensate for added feed costs during drought. We use multiple ranch decision models to simulate the effectiveness of drought adaptations under different rainfall and forage conditions, and with or without range insurance. The results include annual profit and end-of-year net worth after drought responses on a typical Great Plains-Rocky Mountain cow/calf ranch. The simulations illuminate the role of adaptation costs, insurance, and drought early warning in the decision-making process. We also examine alternative drought indices and the effect of drought on cattle markets, both of which feed back to rancher decisions.

WWA/NIDIS Webinar: Evaporative Demand Drought Index (EDDI): Tracking the “Atmospheric Demand” Side of Drought for Monitoring and Early Warning
Imtiaz Rangwala, Mike Hobbins, and Jeff Lukas for the EDDI Team*

EDDI is a drought indicator that examines changes in the atmospheric evaporative demand to indicate the spatial extent and severity of drought over multiple timescales. In this webinar, we will describe the physical basis of EDDI and summarize some early results that demonstrate its potential and added value in early warning and ongoing monitoring of drought. We will also describe the various resources available from the EDDI tool, and share insights gained from our engagement with a diverse set of stakeholders on its effectiveness and usability.

October 23, 2015
WWA & NOAA PSD El Niño panel discussion and webinar

What does the current strong El Niño event mean for this coming snowpack and runoff season in Colorado? WWA and the NOAA ESRL Physical Science Division (PSD) are convening a panel of experts to discuss what El Niño is and what it does, past El Niño impacts across Colorado, and what kind of weather we might expect this fall, winter and spring. After an overview of a 2-page briefing document to be released the same day, the panelists will make brief remarks, followed by questions from the audience.

Panel includes Jeff Lukas (WWA), Klaus Wolter (WWA and NOAA PSD), Nezette Rydell (NOAA NWS) and Marty Hoerling (NOAA PSD).
