Abstract:In the introduction, the usefulness of economic analysis in the valuation of sediment management options is demonstrated for five different stages of the planning process: (i) policy formulation, (ii) the initial search for valid options, (iii) the predesign stage, (iv) determining the scope of the appraisal, and (v) monitoring the performance of completed projects. In the second section of the paper a scheme for classifying the economic and social effects of sediment-related effects on-site and off-site is designed and used to show how the social worth of a sediment management option can be estimated. The treatment of irreversibility, flexibility, externality and uncertainty in benefit-cost estimation is discussed in the third section of the paper, which concludes with a summary of the major points developed.
Keywords:Economic analysis  Sediment management  Planning  Environmental effects  Social  effects  Diseconomy
