This online engineering PDH course provides basic information on hydraulic performance of shallow foundations for the support of vertical-wall bridge abutments.
Scour at the base of bridge abutments during floods is a common cause of bridge failure in the United States. Shallow abutment foundations located at or near the channel banks are considered more vulnerable than other foundations because they are closer to the streambed and can significantly constrict flood flows. These types of abutments are frequently implemented for single-span bridges, and scour countermeasures are often integrated into the design to avoid placing the foundation below local scour depth.
Therefore, to protect small single-span bridge abutments built on shallow foundations from scour damage, methods for countermeasure design are needed that consider the abutment foundation and scour countermeasures as an integrated component of the bridge. The research study described in this course is designed to provide a complete picture of the flow field and local bed shear stresses on heterogeneous bed roughness in the bridge opening.
This 7 PDH online course is applicable to geotechnical engineers who are interested in improving their knowledge about scours occurring at the base of bridge abutment during floods.
This PE continuing education course is intended to provide you with the following specific knowledge and skills:
- Familiarizing with the performed literature research to determine depth and location of scour
- Understanding the proposed guidance on the hydraulic requirements for shallow abutment foundations
- Gaining a general overview of the development of a conceptual model for the increased shear in the middle of the contracted channel section
- Learning about the experimental equipment, program, and findings for several abutment riprap layouts
- Understanding the different design guidelines and requirements for riprap aprons for vertical-wall abutments with shallow foundations
In this professional engineering CEU course, you need to review the course document titled, "Hydraulic Performance of Shallow Foundations for the Support of Vertical-Wall Bridge Abutments”, which is based on the Department of Transportation document “Hydraulic Performance of Shallow Foundations for the Support of Vertical-Wall Bridge Abutments”, Publication No. FHWA-HRT-17-013.

This online engineering PDH course provides information on scour in cohesive soils and presents a study through which an erosion testing device that simulates open channel flow on a small scale was developed and tested. In addition, a recommended design approach is provided that can be used for estimating scour for a range of cohesive soils.
Scour in cohesive soils has been a challenge for engineers and designers. Unlike noncohesive soils, practical measurement techniques and well accepted guidance on the scourability of cohesive soils are severely lacking.
This course focuses on two main objectives. The first is to demonstrate a new ex situ erosion testing device (ESTD) that can mimic the near-bed flow of open channels to erode cohesive soils within a specified range of shear stresses. The second objective is to develop a method for estimating the critical shear stress and erosion rates for a limited range of cohesive soils in the context of the Hydraulic Engineering Circular 18 scour framework.
This 7 PDH online course is applicable to geotechnical and civil engineers who are interested in expanding their knowledge on the topic of scour and erosion processes in cohesive soils.
This PE continuing education course is intended to provide you with the following specific knowledge and skills:
- Familiarizing with cohesive soils and the different factors influencing their behavior
- Understanding the erosion processes in cohesive soils
- Understanding the design, operation, advantages and limitations of the ESTD
- Knowing how the log-law velocity profile is reproduced in the test channel and how boundary shear stress is measured
- Learning about the preparation of soil specimens and soil sample properties
- Learning about the factors affecting erosion and the analytical development of the recommended design relations
- Gaining an overview of future research recommendations in the field

This engineering online PDH course will provide an overview on effective maintenance considerations of tunnel systems and the associated components.
An effective maintenance program helps reduce costs, decrease the number of tunnel closures, increase public safety, and ensure adequate levels of service. To maximize efficient use of resources and minimize costs, maintenance programs should be optimized. When large-scale repairs and upgrades are implemented, these projects are typically referred to as tunnel rehabilitation.
This 2 PDH online course is applicable to civil and structural engineers, as well as design and construction personnel involved with the maintenance process of tunnel systems.
This PE continuing education course is intended to provide you with the following specific knowledge and skills:
- Understanding the fundamental causes of deterioration and corrosion in tunnels.
- Familiarization with the methods aimed at controlling groundwater seepage.
- Familiarization with the repair techniques and rehabilitation schemes.
