Texas Section Webinar Hosted by Houston Branch

The Houston Branch is hosting the webinar being presented by the Texas Section.  $15 meeting reistration includes the webinar and boxed lunch.  

Overview:

Atlas 14 is a National Weather Service (NWS) effort to update precipitation frequency estimates for the entire country. Volumes 1 (Southwest) through 10 (Northeast) were completed from 2006 to 2015. As of 2017, Volume 11 for Texas had not yet been completed. The last state-wide Texas estimate was released by the United States Geological Survey in 2004 (Asquith) using a period of record of rainfall observation from about 1940 to 1998, depending upon the gauge.

On September 27, 2018, the NWS, under the National Oceanic and Atmospheric Administration (NOAA), released the web version of Volume 11 (Version 2.0), covering all of Texas. The Atlas 14 estimate is based on rainfall observations that range from as early as 1880 to 2017 (including Hurricane Harvey), depending upon the gauge. The web version of Atlas 14, Volume 11 allows a user to click anywhere in Texas and obtain point precipitation frequency estimates for rain events ranging from 5-minute durations to 60-day durations and with recurrence intervals ranging from 1 year to 1,000 years.

The webinar will provide a high-level overview of how the new frequency estimates were derived, discuss the significant changes in rain events sizes (particularly the 1% annual chance, 24-hour duration event which is often used to design flood mitigation facilities), and provide some discussion regarding the cost and design implications.

He recently served on Urban Land Institute (ULI) National Technical Assistance Panel for the municipality of Toa Baja, Puerto Rico, which was subject to catastrophic flooding during Hurricane Maria. He was an expert contributor to and reviewer of the ULI report Harvesting the Value of Water: Stormwater, Green Infrastructure, and Real Estate (May 2017).
