Antecedent Precipitation Tool Workshop
The 2020 Navigable Waters Protection Rule is the latest update to the definition of what is a jurisdictional Waters of the US. A significant part of this definition requires the user to limit their wetland delineation work to typical rainfall years. This presents several immediate problems.

We can establish acceptable “normal” ranges within the 30th and 70th percentiles (i.e. 1 standard deviation) from 30 years of local weather data. We can also model wet and dry conditions and calculate the respective hydrological changes to the site as a function of their deviation from “typical.” In addition we will cover the use of USGS StreamStats web application, including the Probability of Streamflow Permanence (PROSPER) tool.
- What are the local weather patterns for the study area?
- What constitutes a wet, dry and normal year for the site?
- How do I know if the current year is typical?
- How do I schedule seasonal work for upcoming wetland delineations?
- What happens if I need to work in a dry or wet year?
These are just a few of the questions that have come out of the new regulations. Fortunately, we have answers to all these questions and more.
Utilizing peer reviewed wetland hydrological design software, we can extrapolate local wet, dry and typical years.
If this sounds a bit scary and more math than you ever expected to have to do for a wetland delineation, don’t fret. Our training will guide you through the process in easy to follow steps resulting in a highly accurate and defensible data analysis. The workshop will show you where and how to access the free NOAA, NRCS and USGS data sets and how to input them into the software. From there we will walk you thought the analysis and modeling of various site scenarios.
The workshop is being offered in an on-demand format. You can log in any time and watch the presentations and work on the assignments. There is not a specific time you need to start the class, and it is available anytime day or night. The class will remain active in your account for 120 days after your start the class.

You will need to download and install the water budget software onto a Windows based PC. The software is provided as part of the class free of charge. It is not currently compatible with Mac or Android (i.e. Chromebooks). We are available help you install the software and you will need admin access to your PC to install. This may require support from your company IT department.
