基于DEM的水位～容积关系计算及误差分析

Stage-Capacity Curve Calculation and Error Analysis Based on Digital Elevation Model

通过理论推导,提出基于数字高程模型计算水位～容积关系的方法,并进行初步误差分析.通过实例验算,表明在地形测量数据允许的条件下,基于数字高程模型计算水位～容积关系的方法对高差明显的地区和地势平坦的平原地区均适用.

This article proposes a new method to calculate relationship between stage and capacity based on DEM and conducts error analysis.Through experiment calculation,it was verified that under the topographic survey data permit conditions,it is adaptability for plain region and large height difference region.
