Available in PDF, EPUB and Kindle. Book excerpt: In prehistoric times, the Santa Cruz River in what is now southern Arizona saw many ebbs, flows, and floods. It flowed on the surface, meandered across the floodplain, and occasionally carved deep channels or arroyos into valley fill. Groundwater was never far from the surface, in places outcropping to feed marshlands or ciénegas. In these wet places, arroyos would heal quickly as the river channel revegetated, the thriving vegetation trapped sediment, and the channel refilled. As readers of Requiem for the Santa Cruz learn, these aridland geomorphic processes also took place in the valley as Tucson grew from mud-walled village to modern metropolis, with one exception: historical water development and channel changes proceeded hand in glove, each taking turns reacting to the other, eventually lowering the water table and killing a unique habitat that can no longer recover or be restored. Authored by an esteemed group of scientists, Requiem for the Santa Cruz thoroughly documents this river—the premier example of historic arroyo cutting during the late nineteenth and early twentieth centuries, when large floodflows cut down through unconsolidated valley fill to form deep channels in the major valleys of the American Southwest. Each chapter provides a unique opportunity to chronicle the arroyo legacy, evaluate its causes, and consider its aftermath. Using more than a collective century of observations and collections, the authors reconstruct the circumstances of the river’s entrenchment and the groundwater mining that ultimately killed the marshlands, a veritable mesquite forest, and a birdwatcher's paradise. Today, communities everywhere face this conundrum: do we manage ephemeral rivers through urban areas for flood control, or do we attempt to restore them to some previous state of perennial naturalness? Requiem for the Santa Cruz carefully explores the legacies of channel change, groundwater depletion, flood control, and nascent attempts at river restoration to give a long-term perspective on management of rivers in arid lands. Tied together by authors who have committed their life’s work to the study of aridland rivers, this book offers a touching and scientifically grounded requiem for the Santa Cruz and every southwestern river.

Available in PDF, EPUB and Kindle. Book excerpt: "Over the millennia, the drainageway we now call the Santa Cruz River has seen many ebbs, flows, and floods. Throughout its long history, the river has meandered. It has flowed on the surface. It has carved deep fissures, and it has widened and narrowed.As readers of Requiem for the Santa Cruz learn, these are events that also have taken place in historic times. Authored by an esteemed group of scientists, Requiem for the Santa Cruz thoroughly documents this river, which flows through Tucson, Arizona, as a prime example of arroyo cutting, a process where heavy rains cut down through rock to create deep channeling. Each chapter provides a unique opportunity to chronicle the arroyo legacy, evaluate its causes, and consider its aftermath. Using more than a century of observations and collections, the authors reconstruct the physical, biological, and cultural circumstances of the river's entrenchment, widening, and subsequent partial filling. Today, communities everywhere face this conundrum: do we manageephemeral rivers through urban areas for flood control, or do we attempt to restore them to some previous state of naturalness? Requiem for the Santa Cruz carefully explores the channel-change legacy, the efficacy of attempts to stabilize it, and the nascent attempts at river restoration to give a long-term perspective on management of rivers in arid lands. Tied together by authors who have committed their life's work to the study of arid-land rivers, this book offers a touching and scientifically grounded requiem for the Santa Cruz and every southwestern river"--

Available in PDF, EPUB and Kindle. Book excerpt: Phoenix is known as the "Valley of the Sun," while Tucson is referred to as "The Old Pueblo." These nicknames epitomize the difference in the public's perception of each city. Phoenix continues to sprawl as one of America's largest and fastest-growing cities. Tucson has witnessed a slower rate of growth, and has only one quarter of Phoenix's population. This was not always the case. Prior to 1920, Tucson had a larger population. How did two cities, with such close physical proximity and similar natural environments develop so differently?Desert Cities examines the environmental circumstances that led to the starkly divergent growth of these two cities. Michael Logan traces this significant imbalance to two main factors: water resources and cultural differences. Both cities began as agricultural communities. Phoenix had the advantage of a larger water supply, the Salt River, which has four and one half times the volume of Tucson's Santa Cruz River. Because Phoenix had a larger river, it received federal assistance in the early twentieth century for the Salt River project, which provided water storage facilities. Tucson received no federal aid. Moreover, a significant cultural difference existed. Tucson, though it became a U.S. possession in 1853, always had a sizable Hispanic population. Phoenix was settled in the 1870s by Anglo pioneers who brought their visions of landscape development and commerce with them.By examining the factors of watershed, culture, ethnicity, terrain, political favoritism, economic development, and history, Desert Cities offers a comprehensive evaluation that illuminates the causes of growth disparity in two major southwestern cities and provides a model for the study of bi-city resource competition.
