Part of: Irrigation and Drainage: Saving a Threatened Resource—In Search of Solutions


As engineers, we tend to focus on the technical aspects of cloud seeding, and may neglect important social aspects or potential side effects. Often people in the target area are more concerned with the problems associated with weather modification. This paper examines and discusses some of the objections to an experimental propane cloud seeding project in northern California. Topics discussed are potential flooding, increased snow removal costs, erosion, depriving downwind people of water, changes in plant and animal communities, and increased smog.
