Closure to 'How to Select a Reference Basin in the Ungauged Regions' by Wensheng Wang, Shixiong Hu, Yueqing Li, and Shuyou Cao

摘要

The writers are very grateful to Fadoua Houssa, Guillaume Lamothe, and Musandji Fuamba from Canada for comment on the original paper. Their discussions and suggestions are good for optimal selecting of a reference basin in the hydrologic analogy method. Hydrologic analogy is an important method for long-term hydrologic prediction and hydrologic calculation in ungauged basins. The key point of hydrologic analogy is how to select a reference basin. The original paper systematically discusses four popular methods to select a reference basin in China, which include (1) grey analysis, (2) fuzzy analysis, (3) projection pursuit (PP), and (4) set pair analysis. Through a case study in a small basin in Hebei Province, North China, the four methods are applied to select a reference basin. In the original paper the advantages and disadvantages of these methods are explored. The results indicate that all these four methods could be used in selecting a reference basin. It will depend on the familiarity and the experiences of the users with a specific method (as presented in the original paper).
