Besides, the water level, flow and temperature in some stations recorded a different degree of coseismic response. The configurations of these responses included sudden rise, sudden drop and slow-change type. The duration of these responses varied.

In recent years, affected by changes of climate and watershed underlying surface conditions, and the influence of water storage operation on cascade hydropower stations in Jinsha River, river water and sediment characteristics also had a series of new changes. Therefore, it is necessary to analyze the characteristics of water and sediment in the reservoir section of the proposed Baihetan hydropower station at present. This paper is starting from this demand, based on the existing data, in Baihetan Hydropower Station Reservoir area of the object. In addition to focusing on the main stream reach, the analysis of the tributary of the reservoir is also included, and by choosing the Baihetan reservoir area located in a storage library control station, outbound control station and tributary control station, using the methods of hydrological mathematical statistics and comparative analysis, taking Baihetan reservoir reach as the object to summarize the basic characteristics of the river water and sediment analysis over the years and adopting conventional hydrological mathematical statistics method and comparative analysis method, the coming water and sediment characteristics in Baihetan reservoir reach over the years have been systematically analyzed, finding out the specific time node of water sediment characteristics and analyzing the causes of change. In conclusion, with current commonly used hydrological statistics method and comparative analysis method, this paper used the existing hydrological data to make systematic analysis on river water and sediment characteristics, laying good foundation for optimizing the operation and management methods of Baihetan reservoir, comparing the change influences and predicting the change trend of water and sediment characteristics after the operation of Baihetan reservoir.","PeriodicalId":349946,"journal":{"name":"Journal of Water Resources Research","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133704484","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

So far, there is no single index or test method can objectively and independently describe the reliability of rainfall forecast results. In order to provide more reference information for the hydrological and meteorological coupling forecast, a complete set of evaluation indexes for precipitation forecast was established by studying with the existing rainfall forecast accuracy assessment methods and the evaluation indexes used in flood prediction. The Qingjiang river basin was chosen as a case study to compare four different meteorological forecast models’ performance in rainfall forecast by using the established indexes.
