河北省水文系列从“63．8”洪水尤其近20年以来，发生了较大的变化，不仅系列增长了，而巨出现了连续枯水年，还出现了“96．8”特大洪水。随着国民经济的飞速发展、人类活动影响日益加剧，下垫面条件也发生了变化，所有这些因素都对水文规律起到不同程度的影响、因此，村水文设计和水文研究成果进行修订和复校以利提高我省水利水电工程的规划、设计及其管理水平。 Hebei Hydrology series has undergone major changes since the “63.8” flood, especially in the past 20 years. Not only the series has grown, but the giant continuous continuous water year has emerged, and the “96.8” extraordinary flood has also occurred. With the rapid development of the national economy, the influence of human activities is getting worse and the conditions of the underlying surfaces also changed. All of these factors have different impacts on the hydrological laws. Therefore, the hydrological design and hydrological research results are revised and reconstructed School to facilitate the improvement of water conservancy and hydropower projects in our province planning, design and management level.
