[email protected] ABSTRACT This essay traces the development of the physical and cultural infrastructure of colonial flood control in the Indus valley. Reconstructing investigations into the causes of a series of floods illustrates the conflict between the idiosyncratic, local knowledge-based, approach of generalists and the reductionist, technologi- cal mentality of engineers. Repeated attempts to protect towns from the Indus River illustrate the growing dominance during the second half of the nineteenth century of an engineering mentality, despite its practical shortcomings.
