An Application to Dam-Reservoir Projects
The use of cost-benefit analysis to evaluate the net welfare payoffs from water projects has now been an established practice for many years. One of the interesting aspects of such cost-benefit studies is that water projects involve an uncertain flow of costs and benefits, arising from the stochastic nature of streamflows. Hence a basic problem for the cost-benefit analyst is that of incorporat...
متن کاملSedimentation in an artificial lake -Lake Matahina, Bay of Plenty
