摘要
对GPS水下地形测量系统进行了简要介绍 ,用其对柘溪水库水下地形进行了实测 ,并根据实测数据修正了柘溪水库库容关系曲线 .与柘溪水库历史水下地形实测资料及建库后水、沙平衡计算得到的资料相比较 ,结果表明 。
The sonic depth recording equipment interfaced with a DGPS(differential global positioning system) was used to survey the underwater area of Zhexi reservoir. The surveyed data was also used to develop topographic maps and to compute elevation storage curve. Furthermore, the loss of reservoir capacity caused by sediment accumulation since dam closure in 1962 was calculated by using three methods based on the surveyed data and the hydrological data. The results are all identical with each other.
