This book examines the intricate web linking water science and society using diverse philosophical lenses. Highlighting the tensions within the threads of this web, we spotlight major conceptual tightropes that water researchers tread daily. To effectively navigate these delicate threads, a healthy tension in the encompassing web is necessary. Drawing inspiration from Freuds examination of tensions in Society and Its Discontents, we illuminate the tension-filled paradoxes inherent to water science, emphasizing the challenges in keeping these paradoxical threads taut enough to ensure a navigable and sustainable bond with society. Central to our narrative is the escalating societal urge to quantify and manage water—something interwoven throughout every environmental layer, including the fabric of our being. An excessive focus on management may alienate users from their water realities, jeopardizing the vital threads that sustainability tether water science and society. Consequently, this book explores compelling and inescapable tensions that resist tidy universal resolution, such as: the language of water science, including its mathematical reductions (i.e., models); the effect of waters commodification on its science; hydrology intersection with colonialism; and other concerns that reveal distortions in our hydrology. We aim to aid water professionals in recognizing and fine-tuning the paradoxes intrinsic to their work. To underscore the interwoven complexity of contemporary hydrology, Hydrology and Its Discontents guides readers into the tempestuous depths of water research, all the while urging a recalibration of perspectives and motivations.
