The ruins of the La Colle Falls Hydro Dam encompass two very distinct topographies: the physical landscape of the vast Canadian Northwest, and the complex emotional terrain of the urban mythology of the city of Prince Albert, Saskatchewan. In 1912 the city embarked on the ambitious project, building a dam and shipping lock on the North Saskatchewan River to supply the city with cheap and plentiful hydroelectric power and create a navigable inland shipping route from Winnipeg to Edmonton. The people of the community believed that it was poised to become a new commercial centre of the west, a key manufacturing and industrial metropolis. Instead, the project became an enormous and ruinous financial debacle that embarrassed the residents and crippled the urban growth of the city for nearly a century. Its failure, and the consequent suffering it brought permeate local legend to this day. The solution to this negative residual memory exists in the hydro dam’s own genesis: the spiritual and functional significance of the North Saskatchewan River as a site of traditional Aboriginal healing and a crucial regional amenity. Unable to bridle the waters of the North Saskatchewan, the dam instead comprises a dramatic visual testimony to the effects of an enormous work of construction on the panoramic Saskatchewan landscape, and an ideal setting to address the interface of man, structure, and the human body in the natural world. This thesis uses the ruins of the dam as a physical armature on which to construct a spa complex, an architectural insertion that will complete the dam, and present a positive alternative ending to its story. The spa is viewed as a place of intimate physical contact and remedial personal reflection that acknowledges the dramatic landscapes surrounding it, engages the senses, and simultaneously heals the bodies of the patrons while reconciling the latent negative historical memory of the original hydro dam project.

This dissertation is a qualitative examination of how the anti-dam movements, with so many disadvantages, are able to pursue their goals in a hybrid democratic political system in Thailand. This dissertation tries to prove that the extra-bureaucratic influence, which emerges from the anti-dam movements are gaining their foothold in the dam politics of Thailand and become a major cause in increase in pluralism in the fragmented authoritarian regime of Thailand. There are two major arguments in the dissertation: Firstly, FA framework, which has already been proved applicable to China by Lieberthal and Oksenberg in 1988 and by Metha in 2008 is also applicable to Thailand. Second argument is that the success of anti-dam movement should not be judged simply by the ability to cancel the project. If we only consider the ability to cancel the project, we may either overestimate or underestimate the ability of anti-dam movement. However, it does not mean that the ability to cancel the dam project does not count at all or should be excluded completely because it still proves the short-term success, which means that the project is cancelled as that moment. In sum, the ¡§success¡¨ of the anti-dam movement mentioned in this dissertation is the ability to transform the state¡¦s decision-making process for the dam project into the direction of more pluralism and less of authoritarianism so that individuals and groups both inside and outside the traditional arenas of policymaking have increasing role in the policy process. Thus the ability to cancel the dam project is an additional indicator not the main one. This view is illustrated through the four case studies: Bhumibol Dam, Nam Choan Dam, Pak Mun Dam, and Kaeng Sua Ten Dam.

In this study, alternative solution of Kayraktepe Dam is investigated. Kayraktepe Dam was planned more than 30 years ago, but due to various reasons the construction could not be realized. In this study, an alternative feasible formulation was developed. Former Kayraktepe Dam was planned for multiple objectives: flood control, energy generation and water supply for irrigation. The newly developed formulation was designed to meet these objects as well.

The lower Trinity River in Texas flows 180 river kilometers from Livingston Dam to Trinity Bay. Like many sandy coastal rivers the lower Trinity is geomorphically active. Within this 180-km reach, the river exhibits three styles of channel geometry and kinematic behavior that have been characterized using aerial photographs spanning the past 60 years, as well as bathymetric surveys and field work completed over the past 5 years. The three channel zones are connected to spatial change in properties of the sediment transport field. The upstream zone is defined by channel-bed incision, relatively small and coarse-grained bars, and relatively low rates of lateral channel migration. These properties of the upstream zone are connected to the discharge of water with effectively no bed-material load from Livingston Dam. Eventually the channel flow scours enough sediment from the channel bed and sidewalls to reestablish the predicted transport capacity for sand in the river, marking the transition to the central zone. This zone is defined by the largest bars and channel bends with the highest rates of lateral migration that persist downstream until the transport of sand and gravel is influenced by the backwater hydraulics connected with the shoreline at Trinity Bay. This downstream river zone is characterized by very small point bars, the deepest flows at most discharges, and lower rates of channel migration. Studying the connections and transitions between these three river zones leads to a more complete understanding of the coevolution of river geometry and profile, channel kinematics, and downstream change in sediment transport in the coastal zone. / text

This is a slide show of selected photographs from the Hoover Dam Ethnographic Study.

This presentation is was given at the Great Basin Conference in 2006 in Las Vegas, Nevada. This talk presents key findings from the report- Ha`tata (The Backbone of the River): American Indian Ethnographic Studies Regarding the Hoover Dam Bypass Project (Stoffle et al. 2000). This talk highlights the pilgrimage trails to Sugarloaf Mountain.

Baihetan Dam is sited on the lower reaches of the Jinsha River in the southwest of China between the boarders of Sichuan and Yunnan province. The dam is scheduled to be taken into operation in the year of 2020 with an installed generation capacity of 14 GW which will put Baihetan Dam on the map as the third largest hydropower station in the world considering installed power output. In comparison, the world’s biggest dam Three Gorges has an installed generation capacity of 22,5 GW. To ensure a sufficient safety evaluation in terms of erosion (scour) formation at the bottom of the plunge pool, pressure simulations in the plunge pool floor in an experimental model at the Department of Hydraulic Engineering in Tsinghua University, Beijing, China has been performed. Data from two experiments with two different outflow configurations has been obtained and analyzed together with three earlier performed experiments on the same experimental model. The results from outflow configuration one had an incomplete data set and could not be compared to the other experiments. The results retrieved from the other experiments however showed the importance of a spillway design with nappe splitters and nappe blocks implemented and the value of a sufficient water cushion in the plunge pool. All four outflow configurations with nappe splitters or nappe blocks implemented held a hydrodynamic pressure below the recommended maximum pressure value of 15 cm water head (experimental model scale) stated by the East Asian Investigation and Design Institute, whilst the one configuration with no nappe splitters or nappe blocks exceeded the value. The design of outflow configuration two is four nappe splitters implemented in two spillways and two nappe blocks in two spillways. In this thesis, this configuration has proven to be the most suitable one in terms of maximum pressure minimization and pressure distribution at the plunge pool floor.
