Hydric Soils Online Training Series

Module 8: Landform and Landscapes – Problematic Landscapes and Parent Materials
Module Description

The module focuses on problematic landscapes and parent materials.  Most hydric soils exhibit certain common morphological characteristics that allow you to identify them as a soil that meets the hydric soil definition. Problem soils are hydric soils that do not exhibit these common hydric soil morphologies. The lack of a morphological indicator despite the soil developing anaerobic conditions in the upper part can be caused by many things including problematic parent material, certain environmental conditions, and the replenishment of iron oxides or new sediments in the upper part of the soil. For some problem soils, alternate morphologies that can only be used in specific problematic situations have been developed. For those problematic situations where an indicator has not been identified, alternative methods of identifying the soil as hydric must be employed. These techniques are outlined in chapter 5 of the Corps of Engineers Regional Supplements.

Target Audience

Wetland field practitioners who need expertise in hydric soils and seek to understand how hydric soils are formed and how to recognize and interpret the information they provide when observed in the field.

Module Learning Objectives

By taking part in this online training, participants should be able to:

  • Identify common morphological characteristics that identify soils that meet the hydric soil definition.
  • Understand that some hydric soils do not exhibit these common hydric soil morphologies.
  • Understand that soil developing anaerobic conditions in the upper part can be caused by many things including problematic parent material, environmental conditions, or the replenishment of iron oxides or new sediments in the upper part of the soil.
  • Identify alternate morphologies that can be used in specific problematic situations.
  • Know where to locate these techniques in the U.S. Army Corps of Engineers’ Regional Supplements.

Link to Online Quiz

To complete this module, use the following link to access the module quiz on ClassMarker.  Once you complete and submit the quiz, it will be automatically graded and you will receive your quiz score and the correct answers.  Passing the quiz will also qualify participants to download a Certificate of Completion that the participant can submit themselves to accrediting organizations for continuing education credits.

To Take the Quiz and Receive a Certificates of Completion for this Module

Participants who both view the module presentation and complete the module quiz are eligible for an ASWM Certificate of Completion for 0.5 hours of training.

Using the ClassMarker online system, ASWM will ask you to certify that you completed viewing the entire hydric soils training module video presentation.

You will need to develop a username and password in ClassMarker. Once you click on the quiz link, you will be prompted again to provide your name and email address, which will be used to process your certificate.

To receive your certificate you must BOTH:

  1. Certify that you completed viewing of the video presentation.  Answering “no” will result in no certificate being issued.
  2. Complete all 5 quiz questions, getting three or more of the questions correct.  You will be provided three attempts to take the quiz for the module.  If at the end of your third attempt you have not been able to get three or more correct, you will not be eligible to receive a certificate.

You will be prompted to download your Certificate of Participation from ClassMarker after you complete the quiz.

Once you download your certificate, you can then submit the certificate to the accrediting organization of your choice to potentially receive continuing education units/credits.
