"One of the world's great karstic aquifer systems, the Edwards aquifer system supplies water for more than 2 million people and for agricultural, municipal, industrial, and recreational uses. This volume reviews the current state of knowledge, current and emerging challenges to wise use of the aquifer system, and some technologies that must be adopted to address these challenges"--
In the 1950s, a series of dams was proposed along the Brazos River in north-central Texas. For John Graves, this project meant that if the stream’s regimen was thus changed, the beautiful and sometimes brutal surrounding countryside would also change, as would the lives of the people whose rugged ancestors had eked out an existence there. Graves therefore decided to visit that stretch of the river, which he had known intimately as a youth. Goodbye to a River is his account of that farewell canoe voyage. As he braves rapids and fatigue and the fickle autumn weather, he muses upon old blood feuds of the region and violent skirmishes with native tribes, and retells wild stories of courage and cowardice and deceit that shaped both the river’s people and the land during frontier times and later. Nearly half a century after its initial publication, Goodbye to a River is a true American classic, a vivid narrative about an exciting journey and a powerful tribute to a vanishing way of life and its ever-changing natural environment.
Because of its large size, topographic diversity, and southcentral position in North America, Texas has a flora of some 5,480 species in 10 natural regions and at least 77 major plant associations. Central in the state's biogeographical pattern is the Edwards Plateau, a strongly dissected tableland, distinctly bordered on the east and south by the abrupt Balcones Escarpment. This volume brings together eight studies of the Plateau originally presented at a symposium sponsored by the Southwestern Association of Naturalists. The aim is to provide an introduction to the vegetational landscape, including representative photographs, specific research about the history of vegetation patterns, and quantitative information on current structure and succession.
Over the past 300 years, settlement patterns, geography, and climate have greatly affected the ecology of the south Texas landscape. Drawing on a variety of interests and perspectives, the contributors to On the Border probe these evolving relationships in and around San Antonio, the country's ninth-largest city.Spanish, Mexican, and American settlers required open expanses of land for agriculture and ranching, displacing indigenous inhabitants. The high poverty traditionally felt by many residents, combined with San Antonio's environment, has contributed to the development of the city's unusually complex public health dilemmas. The national drive to preserve historic landmarks and landscapes has been complicated by the blight of homogenous urban sprawl. But no issue has been more contentious than that of water, particularly in a city entirely dependent on a single aquifer in a region of little rain. Managing these environmental concerns is the chief problem facing the city in the new century.
