Study on Selection of Typical Year with Water and Sediment Based on Fuzzy Clustering Iterative Model

Abstract

In order to reasonably and effectively select the typical year with water and sediment from numerous data, an analysis method of fuzzy clustering iterative model was proposed. Based on the example of Jinji hydrologic station, this paper calculates the model and compares it with the the traditional frequency method. Result shows that it was typical in terms of total amount and distribution of flow and sediment to use this method, and the subjectivity of index weight and classification standard of water and sediment is avoided by using this model. So the method is objective and rational.
