Expand your knowledge of on-site water/wastewater management systems
by learning about the principles of soil hydrology and water flow through
the unsaturated (vadose zone) and saturated (aquifer or perched water)
continuum within the soil profile. Apply the knowledge of saturated-unsaturated
water flow to assess movement of water or wastewater applied to soil
through surface (e.g., irrigation) and subsurface (e.g., buried drip
lines) systems in the presence or absence of a shallow water table.
Learn about water balance analysis and ways to determine the drainage
component of the water balance equation by analyzing vertical drainage
through the vadose zone and lateral flow of water above a slowly permeable
layer within this zone. Become familiar with simple models to analyze
ground water mounding analysis and apply the knowledge gained to verify
and/or modify the design parameters for on-site systems.

Aziz
Amoozegar,
PhD, LSS, is a Professor of Environmental Soil Physics at North
Carolina State University. He joined NCSU in 1983 and has conducted
numerous field and laboratory research studies on the movement
of water and transport of pollutants through the vadose zone
and the upper part of aquifer in North Carolina. Prior to joining
NCSU, Aziz was a Research Associate at the University of Arizona
after receiving his MS and PhD degrees there. At U of A he conducted
laboratory studies to assess movement of pollutants through
different soils, and did mathematical modeling describing movement
of water and transport of pollutants through the vadose zone.
Aziz is the inventor of the Compact Constant Head Permeameter,
also known as the Amoozemeter, for measuring soil saturated
hydraulic conductivity in the vadose zone.

Who Will Benefit From This Course...
This short course is designed for soil science, engineering, hydrology,
geology and environmental health professionals working in site evaluation,
design, and operation of on-site water/wastewater management systems.
The site assessment principles that will be presented in this course
will greatly enhance these professionals’ understanding of soil and ground
water hydrology as related to designing septic system drainfields, spray
and drip irrigation fields, infiltration basins and other on-site systems.
