Study on Hydrologic Forecasting at the Construction Period of Datengxia Hydroproject

摘要

To provide better service of hydrologic forecasting in the construction period of Datengxia Hydroproject that is the largest one under construction on the Pearl River, this paper focuses in analysing the characteristics of the regional floods, and reviewing the hydrologic forecasting work since starting construction, and discussing the hydrologic forecasting methods of the period not only the river closure but also the initial filling. The paper presents some practical work experiences and suitable forecasting methods on the basis of the construction schedule and the river diversion schemes. The study will conducive to improve our service ability of hydrologic forecasting and provide the important technical support of safe construction during the flood season.
