For the past twenty years, the understanding that impervious surface cover as the main causal factor for the ‘flashier’ runoff response of urbanized watersheds, has been the major focus of integrated water-land planning. Such a view however, ignores other processes by which flashy runoff response may be induced through urbanization. Better understanding of specific runoff production processes and broader views of green infrastructure planning are needed.
I recently read an article that posed an interesting question: does the wealth of data that we are now able to collect about every aspect of life make the development of explanatory models and theories moot? All theories and models are reductionist representations of complex real life that are meant to help us understand how things work. But, says the author of this article, in the age of the Petabyte, explanations of why we do the things we do are becoming less important. More important are the development of tools and methodologies that extract the patterns, show the statistical correlations, and find the relationships between all the data that we are collecting.
