Abstract:
With the rapidly economic and social development and population increase, the impacts of human activities aggravate in the Haihe River Basin, resulting in significant changes in the underlying surface conditions. Based on the hydrological data in detail in the Haihe River Basin, the statistical analysis and Mann Kendall rank correlation test were used to analyze the variation rule and trend of storm flood in the Haihe River Basin under the conditions of human activities and climate changes. The results suggested that storm flood has a decreasing trend in the basin. Research results can lay the foundations for the consistency correction of flood series and provide technical support for the planning and management of flood control and drought relief in the basin.
