摘要河流是一个具有沉积和侵蚀交替模式的动力系统。从河流管理的角度来看，沉积和侵蚀都可能产生负面影响。泥沙平衡是在河流管理中采取有效处理泥沙动力学措施的最有价值的工具。拟定沉积物预算既费时又复杂，但非常有益，因为它大大增加了我们对河流系统功能行为和人类影响的了解。本文的主要目的是为河流管理者提供支持泥沙收支研究的论据。这是通过举例说明的好处，从斯海尔德河和莱茵河的河流管理的渠道泥沙预算。我们提出了10个理由，制定泥沙预算的河流管理：泥沙预算有助于：（1）在明显混乱的数据中创建秩序，（2）识别形态问题，（3）找到问题的智能解决方案，（4）制定研究议程和监测策略，（5）优化疏浚和营养策略，（6）协调流域规模的河流管理，（7）评估人类干预的后果，（8）改进数值模型，（9）向社会解释河流管理，（10）培训未来的河流管理者。
ABSTRACT Rivers are dynamical systems with alternating patterns of sedimentation and erosion. Both sedimentation and erosion may have negative consequences from a perspective of river management. A sediment budget is a most valuable tool for taking measures in river management that deal with sediment dynamics effectively. Drawing-up a sediment budget is time consuming and complicated, but very rewarding in that it strongly increases our understanding of the functional behaviour of a river system and the human impact thereon. The main goal of this article is to provide river managers with arguments in favour of sediment budget studies. This is done by illustrating the benefits of channel sediment budgets for river management using examples from the rivers Scheldt and Rhine. We present 10 reasons for drawing-up sediment budgets for river management: sediment budgets help to: (1) create order in the apparent chaos of data, (2) identify morphological problems, (3) find smart solutions to problems, (4) set research agendas and monitoring strategies, (5) optimize dredging and nourishment strategies, (6) coordinate river management on the basin scale, (7) assess consequences of human interventions, (8) improve numerical models, (9) explain river management to society and (10) train future generations of river managers.
