Decision analysis applied to ground water exploration Aginah, Benedict Anekwe


An outline of the essential steps needed in ground water exploration is given. Since drilling for ground water involves a lot of uncertainty, the main concepts of Bayesian decision theory are briefly reviewed. Three models for analyzing ground water decision problems are developed with an emphasis on the well-owner's utility or desirability to actually venture to invest on a water-drilling project. Finally, use of the decision models is Illustrated by applications to a) Ryder Lake District (in British Columbia) - an area where water supply is a problem, with the only source being from underground; and to b) Inches Creek study area where approximately 4500 gallons per minute of ground water is needed for salmon enhancement facilities.
