Waterways and canal-building in medieval England
A book centring on late Anglo-Saxon and Anglo-Norman canals may come as a surprise; it is generally assumed that no such things existed. Persuasive evidence has, however, been unearthed independently by several scholars, and has stimulated this first serious study of improved waterways in England between the eleventh and fourteenth centuries. England is naturally well-endowed with a network of navigable rivers, especially the easterly systems draining into the Thames, Wash, and Humber. The central middle ages saw innovative and extensive development of this network, including the digging of canals bypassing difficult stretches of rivers, or linking rivers to important production centres. The eleventh and twelfth centuries seem to have been the high point for this dynamic approach to water-transport: after 1200, the improvement of roads and bridges increasingly diverted resources away from the canals, many of which stagnated with the reassertion of natural drainage patterns. This new perspective has an important bearing on the economy, landscape, settlement patterns, and inter-regional contacts of medieval England.

The St. Lawrence Seaway and Power Project
The culmination of a century-long dream to link the Great Lakes interior industrial hubs to the Atlantic Ocean, the St. Lawrence Seaway and Power Project stands as one of the largest and most important public works’ initiatives of the twentieth century. Seen as vital to North American commerce and strategic in advancing America’s position on the world stage, the billion dollar seaway and power dam were also a phenomenal feat of engineering involving an unprecedented level of cooperation between Canadian and American agencies and the unrelenting efforts of workers on both sides of the border. Dubbed the greatest construction show on earth, the largest waterway and hydro dam project ever jointly built by two nations consisted of seven locks, the widening of various canals, the taming of rapids, and the erection of the 3216-foot long, 195.5-foot high Robert Moses – Robert H. Saunders Power Dam. In this book, Claire Puccia Parham reveals the human side of the project in the words of its engineers, laborers, and carpenters. Drawing on firsthand accounts, she provides a vivid portrait of the lives of the men who built the seaway and the women who accompanied them. On the fiftieth anniversary of the dedication of the power dam and waterway, this book is a fitting tribute to the hard work and dedication of the project’s 22,000 workers.

Rivers lost, rivers regained : rethinking city-river relations
\"Rivers Lost, Rivers Regained discusses how cities have gained control and exerted power over rivers and waterways far upstream and downstream; how rivers and floodplains in cityscapes have been transformed by urbanization and industrialization; how urban rivers have been represented in cultural manifestations, such as novels and songs; and discusses more recent strategies to redefine and recreate the place of the river within the urban setting\"-- Provided by publisher.

RAILROADS AND AMERICAN ECONOMIC GROWTH
This article examines the historical impact of railroads on the U.S. economy, with a focus on quantifying the aggregate impact on the agricultural sector in 1890. Expansion of the railroad network may have affected all counties directly or indirectly—an econometric challenge that arises in many empirical settings. However, the total impact on each county is captured by changes in that county’s “market access,” a reduced-form expression derived from general equilibrium trade theory. We measure counties’ market access by constructing a network database of railroads and waterways and calculating lowest-cost county-to-county freight routes. We estimate that county agricultural land values increased substantially with increases in county market access, as the railroad network expanded from 1870 to 1890. Removing all railroads in 1890 is estimated to decrease the total value of U.S. agricultural land by 60%, with limited potential for mitigating these losses through feasible extensions to the canal network or improvements to country roads.
