项目摘要

In order to investigate ecohydraulic properties of overgrown vegetation on floodplain, field studies and flood flow analysis were performed in three test reaches of vegetated river channel. The test reaches were chosen so that effects of river restoration and artificial discharge control on vegetation overgrowth were individually evaluated. In addition to the probe measurements of flood flow and vegetation behaviors, aerial photographic surveying was carried out by using a radio control mini-helicopter (falcon-PARS). Decades-long vegetation dynamics were successfully analyzed by hydrodynamic and ecological models, which were verified through comparison with the field data collected after several flood events. It was found how river restoration and discharge control affect ecohydrodynamics of vegetated river reach. The result is to provide a guideline for a sustainable river management strategy with minimum labor and cost.

为了研究植被过度植被对洪泛区的生态水解特性，在植被河道的三个测试范围内进行了现场研究和洪水流量分析。选择了测试范围，以便分别评估河流恢复和人工排放控制对植被过度生长的影响。除了对洪水流和植被行为的探测测量外，还使用无线电控制迷你螺旋体（Falcon-Pars）进行了航空照相测量。通过流体动力和生态模型成功分析了长达数十年的植被动力学，这些模型通过与几次洪水事件后收集的现场数据进行了比较来验证。发现河流的恢复和排放控制如何影响植被河流的生态水力动力学。结果是为具有最低劳动力和成本的可持续河流管理战略提供指南。
