Abstract
In this paper, we use the directional information transmission index which is based on information entropy to investigate the spatial nonuniformity of rainfall in the Huaihe River basin in China, and propose methods of information transfer function, information distance and information area which are employed to determine the area where a rain gauge is capable of representing. The analysis also involves transformation of the rainfall field from discrete state to continuous state.
