NGWA Short Course Focuses on Infiltration and Recharge
The National Ground Water Association is offering the short course, “Induced Infiltration and Artificial Recharge,” Dec. 9 in New Orleans, La.
The course provides an introduction to the theory and methods used to artificially recharge aquifers through induced infiltration by wells and leakage from ponds and lagoons. Topics covered include:
- Vertical and horizontal permeability
- Scales of anisotropy and the effect on infiltration
- Flow-net construction
- Transient seepage rates from lagoons.
Case studies of artificial recharge facilities in California, Florida, and Ohio will be presented. Participants will learn, among other things, how to estimate induced infiltration from a line source (river) to wells in hands-on problem sessions, the rate of rise and decline of hydraulic heads from a recharge lagoon, and the impacts of partial well and riverbed penetration.
The course assumes knowledge and experience using Darcy’s law, the Theis equation, image well theory, and various field methods to measure in situ values of vertical and horizontal hydraulic conductivity. It is recommended that participants have a bachelor's degree in geology or civil/environmental engineering with coursework dealing with groundwater hydrology or hydrogeology.
The course instructor is Scott Bair, Ph.D, a professor in the Department of Geological Sciences, Ohio State University, teaching water resources, hydrogeology, hydrogeologic field methods, and numerical modeling.
