Abstract
The hydrological and meteorological hydro-meteorological support is one important part of the hydropower construction. Accidents caused by flood and rainstorm during construction will be reduced effectively with the help of reliable hydrological and meteorological forecast which also provides critical technical support for flood prevention and construction organization of projects under construction. Based on the practice of the hydro-meteorological support during the construction period of Three Gorges and Jinsha River cascade hydropower station, this article discussed the methods to support and serve hydro meteorology of large-scale cascade hydropower station construction. Meanwhile, this paper also builds up a hydro-meteorology supportive system for hydro-power station under construction which is led by a hydropower development company and associated by local professional institutions. And this research can also be utilized as a reference for other large-scale hydro-power station construction and to support the hydro-meteorology safeguard during the operation period.
Highlights
As the infrastructure, hydropower project is becoming more and more important in the national economy, and it is very important to the economic benefit
To carry out the support service of hydro meteorological during the construction period, to provide timely and reliable hydrological and meteorological forecast and warning information for engineering construction, accidents triggered by heavy rain and floods can be effectively reduced[2]
Hydrological and meteorological support services for large-scale water conservancy projects should need to carry out such works as hydrological and meteorological forecasting and warning, sediment monitoring, station maintenance, technical analysis, information release, emergency management, and data compilation
Summary
Hydropower project is becoming more and more important in the national economy, and it is very important to the economic benefit. To carry out the support service of hydro meteorological during the construction period, to provide timely and reliable hydrological and meteorological forecast and warning information for engineering construction, accidents triggered by heavy rain and floods can be effectively reduced[2]. It is to provide important technical support for the safety of the flood season in the construction period, and it is the accumulating basic data for the analysis of climate change in the operation period of the power station[3]
