Hydrology Tools for Wetland Restoration And Determination (000025)


This course is intended to provide multi agency participants with the knowledge they need to select the right hydrology tools for making a wetland determination in accordance with the requirements of the National Food Security Act Manual (NFSAM). Tools presented may also be used in wetland work hydrology studies.  Participants will learn how to use the seven major tools to perform hydrology studies, and review agency work done by consultants. Tools presented include onsite field indicators, and offsite tools including remote sensing, observation wells, stream-flow and lake gage data, runoff volumes, scope effect equations and the use of DRAINMOD and SPAW software.


Upon completion of this training, participants will be able to:

  • Select and use the tools that best fits site conditions and available data;
  • Use appropriate methodology to make hydrology analysis for wetlands;
  • Accurately document factors needed to delineate wetland hydrology in NFSAM;
  • Describe tools used for complex conditions where the hydrology soil, or vegetation is disturbed;
  • Use the tools to plan hydrology restoration and evaluate its success;
  • Analyze the major components of the wetland water budget; and
  • Demonstrate effective use of the seven major hydrology tools.
