ABSTRACT

Global climate change is known to trigger local and regional hydrologic variations such as changes in precipitation patterns, increased surface temperatures, variations in the streamflow and the occurrence of frequent floods and droughts which in turn affect the built environment. Apt and efficient water management is paramount as climate change can considerably affect the water supply-demand balance. Focusing on reservoir management, the vulnerability to floods and droughts, the effect on energy production, the ability to cope with the agricultural and drinking water demand and the impact on ecological flow need to be reconsidered. The objectives of this paper are to review and identify the impacts of climate change on reservoir hydrology, discuss the related uncertainties and conclude and recommend the ways of adapting to the change. Under reservoir operation, the emphasis is on the consequent need for closer attention of the planners and reservoir operators. Variations in precipitation patterns affect hydropower generation and become a reason for aggravated floods and droughts. Changed evaporation volumes affect the irrigation and drinking water supplies considerably. Several possible approaches are discussed emphasizing long-term basin-wide water resource management. The recommendation is to stress more on the ways of reducing climate change impacts in future studies.

摘要

众所周知，全球气候变化会引发局部和区域水文变化，例如降水模式的变化、地表温度的升高、水流的变化以及频繁的洪水和干旱的发生，这些反过来又会影响建筑环境。由于气候变化会极大地影响水的供需平衡，因此恰当而有效的水管理至关重要。需要重新考虑水库管理、洪水和干旱的脆弱性、对能源生产的影响、应对农业和饮用水需求的能力以及对生态流量的影响。本文的目的是回顾和识别气候变化对水库水文的影响，讨论相关的不确定性，总结和推荐适应变化的方法。在水库运营中，重点是需要规划者和水库运营商的密切关注。降水模式的变化会影响水力发电，并成为水旱灾害加剧的原因。蒸发量的变化极大地影响了灌溉和饮用水的供应。讨论了几种可能的方法，强调长期的流域范围内的水资源管理。建议是在未来的研究中更多地强调减少气候变化影响的方法。蒸发量的变化极大地影响了灌溉和饮用水的供应。讨论了几种可能的方法，强调长期的流域范围内的水资源管理。建议是在未来的研究中更多地强调减少气候变化影响的方法。蒸发量的变化极大地影响了灌溉和饮用水的供应。讨论了几种可能的方法，强调长期的流域范围内的水资源管理。建议是在未来的研究中更多地强调减少气候变化影响的方法。
