【摘要】：水是生命之源,生产之要,生态之基。徒骇河流域降水的年内和年际变化,以及空间分布的不均性给水资源的充分利用带来了困难。为了管理汛期多余水量,有效利用水资源,制定科学、合理的水量调控措施势在必行。虽然徒骇河流域缺少调控水量的大中型水库,但是徒骇河主干道上已建的多级闸坝为充分利用汛期雨量,发挥河道调蓄功能,提供了良好的基础设施。本研究是通过控制闸坝的运行调度来实现丰水枯用,确保雨洪资源的高效利用,并为徒骇河流域水量调控提供理论基础和参考依据。研究内容如下:(1)对徒骇河流域雨洪水特征、雨洪资源利用的可行性进行分析,选取保证率为5%、10%和20%的降水典型年;并以南刘桥闸、营子闸为分界线,将徒骇河流域划分为上、中、下游。(2)分析徒骇河流域的供需关系。徒骇河流域的水资源主要包括地表水、地下水以及引黄客水。需水量主要包括生活需水、农业需水、工业需水和生态环境需水四方面。水资源量供需分析研究表明,徒骇河流域缺水严重,供需矛盾尖锐。(3)利用MIKE11软件建立雨洪演进模拟模型,并对水动力模型(HD)和降雨径流模型(NAM)进行参数率定,并将其进行耦合。设计了闸门全开、水位控制、水位差控制闸坝调度三种模式,结合典型年的选取和闸坝调度模式,进行典型工况下雨洪演进模拟,实现水位和流量过程的可视化。(4)基于徒骇河闸坝典型工况模拟输出的流量和水位结果,结合初始调控水量等指标,计算河道可调控水量。结果表明,通过闸坝的调度运行,可以将更多的雨洪水储存在河道中。峰值河道调控水量和汛期之后河道调控水量遵循同样的规律,调控水量由多到少依次为:水位控制调度、水位差控制调度、全开调度。(5)针对当前徒骇河流域雨洪管控中存在的问题,给出管理和闸坝调控的建议,以期实现徒骇河流域闸坝自动化调度,提高雨洪资源利用效率。
[Abstract]:Water is the source of life, production, ecological basis. It is difficult to make full use of water resources due to the annual and interannual variation of precipitation and the uneven distribution of water resources. In order to manage surplus water in flood season and make effective use of water resources, it is imperative to formulate scientific and reasonable water regulation measures. Although there is a lack of large and medium-sized reservoirs for regulating and controlling water quantity in the river basin, the multistage sluice dams have been built on the main road of the Sunghai River, which provide a good infrastructure for making full use of the rainfall in flood season and giving full play to the regulation and storage function of the river channel. This study is to control the operation and dispatch of the dam to realize the utilization of abundant water and dry water, to ensure the efficient utilization of rain and flood resources, and to provide the theoretical basis and reference basis for the regulation and control of water quantity in the Sunghahe River Basin. The contents of the study are as follows: 1) the characteristics of rain and flood and the feasibility of utilization of rain and flood resources are analyzed, and the typical years of precipitation with a guaranteed rate of 5% 10% and 20% are selected, and the south Liuqiao sluice and Yingzi sluice are taken as the dividing line to divide the Sukhahe river basin into upper ones. Analysis of the supply and demand relationship of the Tuhahe River Basin. The water resources of the river basin mainly include surface water, groundwater and water from the Yellow River. Water demand mainly includes living water, agriculture water demand, industrial water demand and ecological environment water demand. The analysis of water resources supply and demand shows that the water shortage is serious, and the contradiction between supply and demand is sharp. 3) the simulation model of rain and flood evolution is established by using MIKE11 software, and the parameters of the hydrodynamic model (HDD) and the rainfall runoff model (NAM) are determined and coupled. In this paper, three modes of gate opening, water level control and water level difference control are designed. Combined with the selection of typical years and the operation mode of gate and dam, the simulation of rain and flood evolution under typical working conditions is carried out. The visualization of water level and discharge process is realized. Based on the simulated discharge and water level results of typical working conditions of the dam, combined with the initial regulating water quantity and other indexes, the adjustable water volume of the river channel is calculated. The results show that more rain and flood can be stored in the channel through the operation of the dam. The regulation of the peak river and the amount of water after flood season follow the same law. The order of the amount of regulation from more to less is: water level control, water level difference control. In allusion to the problems existing in the control of rain and flood in Tuanhai River basin, the suggestions of management and dam control are given in order to realize automatic dispatching of dam and improve the utilization efficiency of rain and flood resources in the basin.
