Lunch (On your own) 12:00 – 1:00 pm
Afternoon Session 1:00 – 4:30 pm
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, RECPs, 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

Speakers
Albert 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.
