人工蓄水是人类生活用水、灌溉用水和能源生产用水的重要来源，是大坝建设所产生的人工蓄水，对人类文明的可持续健康和福祉至关重要。此外，大坝水库还用于娱乐、通航，并为下游山谷提供安全，抵御极端洪水和干旱。所有水库都受到沉积的影响，如果没有适当的预防和缓解措施，就会威胁到水库的可持续性。水库泥沙淤积不仅会导致水库蓄水能力的明显损失，还会影响水库重要出水口结构的进水口和底出水口的充分安全运行。本远景文件首先阐述在防止和减轻水库沉积措施方面的最新技术和主要科学进展。然后，指出了主要的研究挑战，这些挑战来自于对剩余开放性问题的评估。还讨论了研究沉积过程的新兴研究方法。
ABSTRACT Artificial water storage, originated by the construction of dams, is essential for the sustainable health and welfare of civilizations since it supplies water for human consumption, irrigation and energy production. Furthermore, dam reservoirs are used for recreation, navigation and they provide safety in the downstream valleys against extreme flood events and droughts. All reservoirs are subjected to sedimentation which, without adequate prevention and mitigation counter-measures, threatens their sustainability. As well as the evident loss of storage capacity, the adequate and safe operation of water intakes and bottom outlets belonging to the vital outlet structures can be affected by the deposition of sediments in the reservoir. This Vision Paper first addresses the state-of-the-art and the main scientific advances in terms of prevention and mitigation measures against sedimentation in reservoirs. Then, the main research challenges, which result from the assessment of what are the remaining open questions, are pointed out. The emerging research methodologies to study sedimentation processes are also discussed.
