Beyond dams and diversions, the author extends the cultural dimension of watercourses to take in their more ethereal property of 'flow' ... a thought-provoking thesis on a very wide-ranging subject, which deserves much greater consideration. -- Stuart Nisbet, University of Glasgow …this is an ambitious book with a big argument.[…]Commendably, Edgeworth uses the theoretical literature and theoretical perspectives critically yet effectively, i.e., actor-network theory, symmetrical archaeology, phenomenology, etc., both to think through the case studies and to support his broader argument about the utility of the concept of flow. -- Cecelia Feldman Weiss, University of Massachusetts Amherst * The New England Classical Journal *
