Open Channel Flow

   Two approaches to channel design

      • Stable bed

      • Unstable bed

   Controlling channel erosion; stable bed

      • Maximum permissible velocity

      • Shear stress

   Manning’s Equation 

Influence of Channel Linings

   Channel linings (vegetation, rolled erosion – control products (RECPs), 
     turf reinforcement mattings (TRMs), hard linings)

   Manning’s Equation parameters

   When Manning’s n is constant, n ≠ f(d)

   Rock-lined channels, n = f(d, D50)

   Vegetation-lined channels, n = f(V, R, vegetation)

Stable-Bed Design

   Maximum permissible velocity designs

Unstable-Bed Designs; Stream Restoration

   Flow competence

   Sediment transport

Flow Regimes

   Subcritical flow

   Critical flow

Continuing Education Credit Information

This seminar is open to the public and provides up to 6.5 PDHs to professional engineers, professional land surveyors, and professional geologists in most states, including Pennsylvania. The Pennsylvania State Board of Professional Engineers, Land Surveyors, and Geologists does not pre-approve continuing education actives.

This seminar is approved by the Landscape Architect Continuing Education System for 6.5 HSW PDHs.

HalfMoon Education is an approved continuing education sponsor for engineers in Florida, Indiana, Louisiana, Maryland, New Jersey (Approval No. 24GP00000700), New York (NYSED Sponsor No. 35), North Carolina, and North Dakota.

The Association of State Floodplain Managers has approved this event for 6.5 CECs..

Attendance will be monitored, and attendance certificates will be available after the seminar for most individuals who complete the entire program. Attendance certificates not available at the seminar will be mailed to participants within fifteen business days.

Speakers

Albert R. Jarrett

Dr. Jarrett is Professor Emeritus of Agricultural and Biological Engineering at The Pennsylvania State University. He has over 40 years of experience teaching and researching erosion and sediment control, water management, impoundment design, drainage, and stormwater management. Dr. Jarrett has taught soil and water management to engineers and non-engineers. He has prepared engineers for careers in the USDA-Natural Resources Conservation Service (NRCS) and the engineering consulting industry, especially land development projects with both stormwater and erosion and sediment control plans as required in Pennsylvania. Basic soils and water-movement elements of soil physics have been part of his courses. Dr. Jarrett is considered one of the leading erosion control researchers and has contributed many refereed publications, textbooks, and extension fact sheets relating to stormwater management and erosion and sediment control. He is a member of the International Erosion Control Association (IECA) and a fellow in the American Society of Agricultural and Biological Engineers.
