摘要
库容是水库的一项重要指标,但在高山峡谷中的水库库容与水位高程呈现非确定关系性.本文对此类水库的库容与水位高程建立了水位-库容函数模型,首先,利用机载激光雷达和多波束水深测量系统采集的库区数字高程模型(DEM)数据和获取的水库各高程面面积,计算对应的库容;其次,使用Matlab工具将水位-库容函数模型根据实际情况分高程段进行多项式拟合建模、筛选和分析等,获得具有较高精度的水位-库容函数模型,对水库的安全运行管理具有一定的实用意义.
Abstract
Storage capacity is an important index of reservoir,and it is uncertain for the relationship between storage capacity and water level in alpine canyon reservoirs.So the water level-storage capacity function model is established in this paper for such reservoirs.Firstly,the DEM data of the reservoir area collected by airborne LiDAR and multi-beam bathymetry system,as well as the area of each vertical surface of the reservoir obtained are used to calculate the corresponding storage capacity.Then Matlab tools are used to model,sceen and analyze the water level-storage capacity model according to the real situation to get a high-precision water level-storage capacity model.The model has important practical significance for the safe operation and management of the reservoir.
