"Undercurrents of Urban Modernism: Water, Architecture, and Landscape in California and the American West" conducts an art-historical analysis of historic waterworks buildings in order to examine cultural values pertinent to aesthetiteics in relationships between water, architecture and landscape in the 19th and early 20th centuries. Visual study of architectural style, ornamental iconography, and landscape features reveals cultural values related to water, water systems, landscape/land use, and urban development. Part 1 introduces a historiography of ideas of "West" and "landscape" to provide a context for defining ways in which water and landscape were conceived in the United States during turn-of-the-century urban development in the American West. Part 2 provides a historical context for California waterworks with a discussion of major U.S. city waterworks from 1799 to 1893 in Philadelphia, Louisville, New York, and New Orleans. Primary architectural styles discussed are Greek Revival, Egyptian Revival, and Roman Revival. Part 3 presents the dissertation's central object of study: waterworks and hydropower architecture for the greater San Francisco Bay Area between 1860 and 1939. From substations to dams, architects who designed waterworks structures drew from historical revival, academic eclecticism, and structural design traditions. The specific waterworks structures anchoring inquiry in this chapter are two round, peripteral, neoclassical water temples built for San Francisco's water supply to mark key underground aqueduct features. I analyze these two temples--the Sunol Water Temple from 1910 and the Pulgas Water Temple from 1939--in formal terms as well as from within broader urban and historical contexts. Part 4 culminates the dissertation with a case study of two dams whose aesthetic features were obscured by unneeded buttresssing when concerns for dam safety arose after a Southern California dam failure had killed several hundred people in 1928. I inquire into a cultural ambivalence stemming that seems to stem from historical conflicts determining the relative aesthetics of "use" and "beauty" in utilitarian waterworks structures. The overall questions in this dissertation inquire into ways in which aesthetic aspects of architectural design of waterworks structures expressed cultural values regarding water, architecture, and landscape in California between 1860 and 1939. / text

The settlement history of the Vredefort Dome can be described as a process of cultural development. The Vaal River hydrosphere, which was for many years a prestigious settlement site, initially attracted large scale game and later livestock farmers. The drifts were a central part of a network of early strategic communication routes and outspans. From 1838, pioneer settlement, farm occupation and agricultural development followed, and the area eventually entered an agriculture-mining era. Gold-mining stimulated the regional economy and also played a significant role in the development of towns in the area. The Vaal River did not play a significant role from a mining perspective, but featured more prominently in the development of villages and, in a sense, served as a political boundary. The location of the water source often determined where people settled permanently. It also decided the position of the house and yard. From the outset, riparian dwellers attempted to manipulate the flow of the river by creating dams and utilising water for irrigation and domestic purposes. Drought conditions also left historical traces; water management projects upstream transformed the Vaal River into a steadily flowing stream, which led to the economic and cultural segregation of north and south. Man's fear associated with drought (too little water), floods (too much water), meteorology (the necessity of water), and the role of the supernatural (divining water) and superstition (the water snake stories) were expressed in the interaction between people and this water environment. A wide variety of people with distinct cultures lived alongside each other in the area. Western and African cultural goods, as well as customs and beliefs, were mutually adopted by these different cultural groups as a result of this contact. The way land has been used in the Dome area has evolved over the years. The culling of game made way for the permanent establishment of the livestocktravelling farmer. Hereafter prolonged drought conditions destroyed pastures and, consequently, large areas of land were ploughed for agricultural use. Agriculture, which is more labour intensive and needs more water for irrigation, was replaced by game farming, which is less labour intensive and requires less water This world heritage site has drawn global interest and ecotourism has attracted visitors to the Vaal River area. The riparian dwellers, however, remain victims of up-stream industrial and sewage pollution; in future, they are likely to fall prey to acid mine water pollution, with disastrous consequences. / PhD (History), North-West University, Vaal Triangle Campus, 2013

The St. Lawrence Seaway and Power Project, built cooperatively between 1954 and 1959 by Canada and the United States, is the largest navigable inland waterway in the world and the largest borderlands project ever undertaken jointly by two countries. This thesis combines diplomatic, political, and environmental history to chart the course of domestic and international negotiations, particularly in the 1945-1954 period, that resulted in the bilateral 1954 agreement to build the seaway. The focus is on the Canadian federal government and to a lesser extent the U.S. federal government, as well as involved state and provincial governments and their public power utilities. These negotiations are extremely revealing in terms of the history of Canadian-American relations, and this thesis also examines issues connected to North American attitudes toward water resources, state-building, high modernism, and technology in the early Cold War period. After a number of failed attempts at a cooperative waterway, in the late 1940s the Liberal government of Louis St. Laurent began to explore the possibility of an all-Canadian seaway, and backed by widespread public support, had adopted this as policy by 1952. The drive for an all-Canadian seaway stemmed from various forms of nationalism which framed the St. Lawrence as an exclusively “Canadian” resource that was intimately tied to Canadian identity. However, the Truman administration and different American interests deemed a unilateral Canadian waterway to be an economic and national security threat to the United States, and delayed the requisite power licenses needed for Canada to undertake the transborder St. Lawrence project. Canada partly contributed to this situation by repeatedly making vague offers to leave the door open for American involvement in the hopes that this would expedite the hydro aspect of the project. The Eisenhower administration also stalled Ottawa’s efforts to “go it alone” until American participation was finally sanctioned by Congress in 1954 and the requisite licenses were granted. The St. Laurent government then reluctantly acquiesced to the American desire for a joint endeavour in order to maintain harmonious Canada-U.S. relations, although Canada did extract key concessions from Washington about the shape and placement of the project.
