天然河流建库后下游的河床演变,与生产实践关系密切,是一个重要而又极为复杂的问题。随着四化建设的进展,河流综合开发日益增多,要求较全面地回答这个问题也就越来越显得迫切了。但是,从目前看来,对问题的研究还有待于继续深入。笔者根据航道工程建设的需要,通过柘林水库下游河段等实例的调查研究,对在少沙河流上兴建蓄水式水库以后下游的河床演变,获得一些初步认识,下面扼要介绍,并着重从日调节波的特性和影响方面探讨。
The river bed evolution downstream of the natural river after reservoir construction is closely related to production practice is an important and extremely complicated issue. With the progress of the four modernizations and the increasing comprehensive development of rivers, it is more and more urgent to demand a more comprehensive answer to this question. However, at present, the research on the issue needs to be further deepened. According to the needs of the construction of waterway project, through the investigation and research of the lower reaches of Zhelin Reservoir, some preliminary understandings are given to the riverbed evolution after the construction of water storage reservoir in Shaosha River. The following is a brief introduction, Discussion on the Characteristics and Effects of Daily Regulating Waves.
