Dear VAWP members and other interested parties:

Due to popular demand, we are making recordings of our Spring 2021 webinar series accessible online to those who are unable to attend the live events. The fourth of our Spring 2021 webinar series, entitled “The Antecedent Precipitation Tool (APT)” is provided below.

Eli Wright, Timmons Group Senior Environmental Scientist, and Dr. Herman W. Hudson III (Wes), United States Army Corps of Engineers Environmental Specialist, presented on: The Antecedent Precipitation Tool (APT)

The Antecedent Precipitation Tool (APT) is an automation tool that the U.S. Army Corps of Engineers (USACE) developed following implementation of the Navigable Water Protection Rule (NWPR) in 2020. The ATP is used to facilitate the comparison of antecedent or recent rainfall conditions for a given location to the range of normal rainfall conditions that occurred during the preceding 30 years. In addition to providing a standardized methodology to evaluate normal precipitation conditions, the APT can also be used to assess the presence of drought conditions, as well as the approximate dates of the wet and dry seasons for a given location.

This webinar was hosted by Timmons Group using Zoom. Thank you, Timmons Group!
