摘要

Small Hydropower Projects (SHPP), i.e., those with capacities of 1000 kW or less, have great potential for elevating the standard of living and contributing to the economic growth of isolated rural communities in developing countries. However, construction and operation of a SHPP can result in adverse environmental impacts that should be considered in the initial stages of site selection and development. Environmental concerns can be factored into a site selection process both at the prefeasibility and feasibility stages. The prefeasibility study is the process by which a large number of potential sites is reduced to a much smaller number of candidate sites based on coarse-grained engineering, socioeconomic, and environmental criteria. Although many of the factors determining the suitability of a given site at the prefeasibility stage involve basic engineering or economic questions (e.g., availability of water and demonstrated need for power), four fundamental environmental issues that should be addressed are discussed in this report. The feasibility study is the final stage of site selection, where a relatively small number of candidate SHPP sites are examined in greater detail and the best are selected for development. Potential environmental impacts of SHPP's are discussed, and a checklist of environmental data that should be collected in order to judge the significance of the projected impacts is provided. Finally, recommendations are made as to the necessary training and capabilities of the personnel involved in the site selection studies and the general procedures by which the studies may be conducted.
