Abstract
Recent calls for drainage basin classification have highlighted the advantages of such efforts, including: identification of important controls on water fluxes and pathways; guidance on basin similarities and differences that could facilitate modelling and experimental approaches; and provision of a common language to assist in the discussions of inter-basin similarities and differences at regional, national, and global scales. There are several examples of basin classification in terms of hydrograph characteristics, such as the work of Richards (1990) and Poff et al. (1997) in North America and Harris et al. (2000) in the United Kingdom. These classification schemes have often been based on streamflow response, which integrates spatial patterns in hydrological processes that control streamflow measured at the gauging station, with the goal of identifying the linkages between streamflow properties and aquatic ecology. These classification efforts may be of considerable assistance in understanding the ecological significance of flow regimes and their management in order to protect or restore fluvial systems. However, their ability to infer the nature, magnitude, and spatial and temporal distribution of intra-basin hydrologic processes based on streamflow behaviour is limited. Information on the internal hydrologic behaviour of drainage basins is particularly needed to identify inter-basin similarities and differences in terms of their response to natural and anthropogenic disturbance (e.g. climatic change, fire, insect infestation, forest management, urban development).
